Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In one embodiment, as shown in fig. 1, a power capacity boosting method is provided, comprising:
step S110, the first power division and phase modulation module obtains an original transmitting signal, divides the original transmitting signal into a preset number of sub transmitting signals, and sends the preset number of sub transmitting signals to the transmitting ports of the duplexers with the same preset number respectively.
The first power division phase modulation module is a functional module with power distribution and phase adjustment functions, and comprises a power distribution part and a phase adjustment part, wherein the power distribution part can be realized by a power distributor, and can be electric bridges of various types, such as a 3dB electric bridge, a 5dB electric bridge and the like, and can also be power distribution network structures of various types, such as a Wilkinson power distributor and the like. After the original transmitting signal is obtained, power distribution is carried out on the original transmitting signal according to a preset circuit, the original transmitting signal is divided into a preset number of sub transmitting signals, each sub transmitting signal shares the power of the original transmitting signal, and the power corresponding to each sub transmitting signal can be the same or different. Further, phase adjustment is performed on different sub-transmitting signals according to different requirements, for example, different microstrip line lengths are arranged in the channel to change the phase of the sub-transmitting signals, and phase modulation is performed on the sub-transmitting signals. Specifically, the power division phase modulation module can perform power distribution first and then phase modulation, can perform phase modulation first and then power distribution, and can also achieve the phase modulation function by using the power distribution circuit.
Furthermore, after the original transmitting signal is divided into a preset number of sub transmitting signals by the first power division and phase modulation module, the sub transmitting signals correspond to the duplexers one by one, and different sub transmitting signals are respectively input into different duplexer transmitting ports and then output from antenna ports corresponding to the duplexers.
Step S120, the second power division phase modulation module obtains a preset number of sub transmission signals from the antenna ports of the preset number of duplexers, and combines the preset number of sub transmission signals into one transmission signal for output.
When a signal enters from an input port of the power division phase modulation module, the power distribution circuit divides one path of original signal into multiple paths of sub-signals and outputs the sub-signals from different ports; when a plurality of different signals are input from different ports of the power division phase modulation module, the power distribution circuit can synthesize multiple paths of signals into one path of signal, namely, the input end of the power division phase modulation module signal is changed, and the second power division phase modulation module has the function of combining when the signals are input from the multiple paths of output ends.
Specifically, the second power division phase modulation module obtains corresponding output sub-transmission signals from antenna ports of different duplexers, and then synthesizes different sub-signals into one signal under the action of the power distribution circuit. In particular, the sub-transmitting signals are not necessarily acquired simultaneously, and the sub-transmitting signals may be acquired at different times, and then corresponding time delays are set according to the time of acquiring the sub-transmitting signals, so as to ensure that the sub-transmitting signals output by all duplexers are combined at the same time. Further, if the first power division phase modulation module performs phase modulation on the sub-transmission signals in the process of dividing the original transmission signals into the preset number of sub-transmission signals, corresponding processing is performed on the sub-transmission signal input ports corresponding to the second power division phase modulation module, the phases of the sub-transmission signals are adjusted, and the sub-transmission signals are adjusted to be signals with the same phase. In particular, the power of the transmission signal synthesized by the second power division phase modulation module is the same as the power of the original transmission signal obtained by the first power division phase modulation module, without considering signal loss. The first power division phase modulation module and the second power division phase modulation module have functions of power distribution and phase adjustment, and circuits for realizing the power distribution function and the phase adjustment in the first power division phase modulation module and the second power division phase modulation module can be the same or different.
Furthermore, the first power division phase modulation module, the duplexer and the second power division phase modulation module are arranged in a transmitting channel of the base station and used for carrying out shunting and combining on a transmitting signal so as to ensure that the low-power duplexer can meet the requirement that the high-power base station transmits a high-power signal.
In this embodiment, the original transmitting signal is divided into a preset number of sub transmitting signals by the first power division and phase modulation module, and the power of the original transmitting signal is dispersed into each sub transmitting signal, so that the power of the transmitting sub signal input into each duplexer is small, and the power requirement of a single duplexer is met, each sub signal can be input into a corresponding duplexer and output from the corresponding duplexer, and the sub transmitting signals output by each duplexer are obtained by the second power division and phase modulation module, and are recombined into a transmitting signal for output. The original transmitting signal is subjected to shunting, phase modulation and combining operation through the power division and phase modulation module, the power of the original transmitting signal is shared by the plurality of duplexers, and the sub-signals are transmitted respectively, so that the low-power duplexer can be applied to a high-power base station, and the application range of the low-power duplexer is enlarged.
As shown in fig. 2, in one embodiment, there is provided a power capacity boosting method, including:
step S210, the second power division and phase modulation module obtains an original receiving signal, divides the original receiving signal into a preset number of sub receiving signals, and sends the preset number of sub receiving signals to the antenna ports of the duplexers with the same preset number respectively.
The second power division phase modulation module is used for synthesizing the sub transmitting signals into a path of transmitting signals to be sent to the antenna, plays a role of combining and is equivalent to a combiner; for the received signal, the second power division and phase modulation module is used for acquiring the received signal and dividing the received signal into a preset number of sub-received signals, which is equivalent to a power divider.
Specifically, the second power division phase modulation module divides the original receiving signal into a preset number of sub-signals, and sends each path of sub-receiving signal to the antenna port of the duplexer in a one-to-one correspondence with the duplexer, so that the sub-receiving signal is output from the receiving port of the duplexer. The transmitting signal is input from the transmitting port of the duplexer, the antenna port is output, the receiving signal is input from the antenna port, and the receiving signal is output from the receiving port, so that the transmitting signal and the receiving signal are effectively separated.
In step S220, the third power division and phase modulation module obtains a preset number of sub-received signals from the receiving ports of the preset number of duplexers, and synthesizes the preset number of sub-received signals into a received signal for output.
The third power division phase modulation module also has the functions of power distribution and phase adjustment, and the circuits for realizing the power distribution function and the phase adjustment in the second power division phase modulation module and the third power division phase modulation module can be the same or different. The third power division module is connected with the receiving ports corresponding to the duplexers, respectively obtains corresponding sub-receiving signals from each duplexer receiving port, and combines the sub-receiving signals with preset number into one path of receiving signal to be output. Specifically, when the original received signal is divided into a preset number of sub-received signals by the second power division and phase modulation module, if the phases of the sub-received signals are different due to the power distribution circuit, the phase modulation module of the third power division and phase modulation module is designed reasonably, and the sub-received signals entering the third power division and phase modulation module are adjusted into sub-received signals with the same phase and then combined.
Furthermore, the second power division phase modulation module, the preset number of duplexers and the third power division module form a signal receiving channel, and the signal transmitting channel and the signal receiving channel share the second power division phase modulation module, so that the first power division phase modulation module, the second power division phase modulation module, the third power division phase modulation module and the preset number of duplexers form a structure similar to a duplexer, and a received signal can be isolated from a transmitted signal.
In this embodiment, the power of the original received signal is dispersed to each sub-received signal through the second power division phase modulation module, so that the power of the received sub-signals input into each duplexer is relatively low, the power requirement of a single duplexer is met, each sub-signal can be input into a corresponding duplexer and output from the duplexer, and then each sub-signal is synthesized into one received signal by using the third power division phase modulation module. By means of the operation of shunting, phase modulation and combining of the received signals, the low-power duplexer can be applied to a high-power base station, and the application scene of the low-power duplexer is enlarged.
In one embodiment, the amplitude ratio and the phase ratio between the sub received signals are the same as the amplitude ratio and the phase ratio between the sub transmitted signals, respectively.
Specifically, the second power dividing and phase modulating module is used for combining the sub-transmitting signals and splitting the receiving signals, and for the same power dividing and phase modulating module, the amplitude ratio and the phase ratio between the multiple paths of signals to be combined should be the same as those between the multiple paths of signals to be divided. Therefore, the sub transmission signals divided by the first power division phase modulation module and the sub reception signals divided by the second power division phase modulation module have the same amplitude ratio and phase ratio. Further, before the sub received signal or the sub transmitted signal is input to the duplexer, the amplitude ratio and the phase ratio are not particularly required, and the power of the sub signal may be randomly distributed.
As shown in fig. 3, in an embodiment, step S110 further includes:
step S110A, determining the preset number of duplexers according to the rated power of the current base station, the rated power of the duplexers, and the type of the power division and phase modulation module.
In particular, the nominal power of a base station affects the range of signal coverage of the base station, and thus the power of its transmitted signal is determined for a particular base station. The duplexer also has a fixed rated power and basically does not change in the using process, so that if a single small-power duplexer cannot bear a high-power signal, a plurality of small-power duplexers need to be combined for use. The power division phase modulation modules have different circuit principles and different numbers of distributed sub-signals. For example, a 3dB bridge can divide a signal into two signals, and an N-order Wilkinson power divider can divide a signal into N paths. The number of the duplexers is determined by combining the rated power of the base station, the rated power of the used duplexer and the type of the power division and phase modulation module, so that the power of a signal entering each duplexer cannot exceed the rated power of the duplexer, and the duplexer is prevented from being damaged.
In one embodiment, step S120 includes: the second power division phase modulation module respectively inputs the preset number of sub-signals into corresponding channels according to the phase conditions of the preset number of sub-signals output by the duplexer, so as to adjust the preset number of sub-signals into sub-signals with the same phase, and synthesize the preset number of sub-signals with the same phase into a path of transmission signal for output.
The first power division phase modulation module and the second power division phase modulation module respectively comprise a phase regulator and a power divider. The power divider is used for dividing power, and the phase adjuster is used for adjusting phase. The phase adjustment is usually performed using a microstrip line as a phase adjuster, the microstrip line being a microwave transmission line composed of a single conductor strip supported on a dielectric substrate. The microstrip line length adjusting device can transmit signals and has the function of directionally transmitting the signals, different influences are caused to the signals by different microstrip line lengths, and the signal phase can be adjusted by adjusting the microstrip line length. The connection relation between the microstrip lines with different lengths corresponding to the power division phase modulation module and the duplexer is preset, so that the phase offset and the transmission channel of different sub-signals are determined according to the length of the microstrip lines.
Specifically, different sub-signals correspond to different transmission channels, and if the first power division and phase modulation module performs phase modulation on the sub-transmission signals, the length of the microstrip line is increased in a transmission channel of a certain path of sub-transmitting signals, the phase of the corresponding sub-transmitting signals is adjusted, the phase of the sub-transmitting signal is not changed by the duplexer, so that according to the distribution condition of the microstrip line in the first power division phase modulation module, the antenna port of the duplexer to which different sub transmitting signals are input is connected with the corresponding microstrip line in the second power division phase modulation module to ensure that the different sub transmitting signals are subjected to phase adjustment through different transmission channels, and adjusting the sub-transmitting signals with changed phases to initial phases or adjusting the phases of the sub-transmitting signals without changed phases to the same phases as the sub-transmitting signals with changed phases, so that all the sub-transmitting signals are adjusted to the same phase signals. If the first power division phase modulation module is used to divide the original transmission signal into two paths of sub transmission signals, the microstrip line corresponding to the transmission channel of the first sub transmission signal is added, the phase of the first sub transmission signal is adjusted to be 45 degrees, the phase of the second sub transmission signal is 0 degree, when the first sub transmission signal and the second sub transmission signal are output from the antenna port of the duplexer, the transmission channel of each path of signal is limited by the microstrip line in advance, the length of the microstrip line is added in the channel corresponding to the second sub transmission signal in advance, so that the phase of the second sub transmission signal is adjusted to be 45 degrees and is in phase with the first sub transmission signal, and loss caused by different phases in the process of synthesizing the first sub transmission signal and the second sub transmission signal is avoided.
Furthermore, because the original transmission signal is divided into a plurality of sub-signals with the same or different powers by the first power division phase modulation module, under the condition of not considering signal loss, in order to enable the sub-signals to be re-synthesized into the signal with the same power as the original transmission signal in the second power division phase modulation module, the phase adjuster in the second power division phase modulation module corresponds to the phase adjuster in the first power division phase modulation module, and the power divider in the second power division phase modulation module corresponds to the power divider in the first power division phase modulation module, so that the multi-path sub-signals with different phases can be adjusted into the sub-signals with the same phase, and the input multi-path signals can be received for combining.
In this embodiment, the length of the microstrip line in the first power division and phase modulation module is preset to determine the transmission channels and phase offsets of different sub-transmission signals, and meanwhile, the length of the microstrip line of the corresponding transmission channel of the second power division and phase modulation module is set according to the first power division and phase modulation module, so that the phases of the sub-signals when entering the second power division and phase modulation module for combining are the same.
In one embodiment, step S220 includes: the third power division phase modulation module respectively adjusts the sub-receiving signals with the preset number into sub-receiving signals with the same phase according to the phase conditions of the sub-receiving signals with the preset number, and synthesizes the sub-receiving signals with the preset number and the same phase into one receiving signal to be output.
Specifically, the second power division phase modulation module and the third power division phase modulation module both include a phase adjuster and a power divider, and a circuit for implementing a power distribution function and a circuit for implementing a phase adjustment in the second power division phase modulation module and the third power division phase modulation module may be the same or different. The second power division phase modulation module for obtaining the original receiving signal and the second power division phase modulation module for combining the sub transmitting signals are the same module.
The principle that the second power division phase modulation module carries out power distribution and phase adjustment on the original receiving signal is the same as the process and the principle that the first power division phase modulation module carries out power distribution and phase adjustment on the original transmitting signal, and the principle that the third power division phase modulation module carries out phase adjustment and power synthesis on the sub-receiving signal to output the synthesized receiving signal is the same as the principle that the second power division phase modulation module carries out phase adjustment and power synthesis on the sub-transmitting signal to output the synthesized receiving signal.
In this embodiment, the length of the microstrip line in the second power division and phase modulation module is preset to determine the transmission channels and the phase offsets of different sub-received signals, and meanwhile, the length of the microstrip line of the transmission channel corresponding to the third power division and phase modulation module is set according to the second power division and phase modulation module, so that the phases of the sub-received signals when entering the third power division and phase modulation module for combining are the same.
In one embodiment, as shown in fig. 4, a power capacity improving apparatus is provided, which includes a first power division and phase modulation module 410, a predetermined number of duplexers 420, a second power division and phase modulation module 430, and a third power division and phase modulation module 440;
the first power division phase modulation module 410 is connected to a transmitting port of the duplexer, and is configured to divide an original transmitting signal into a preset number of sub transmitting signals;
the second power division and phase modulation module 430 is connected to the antenna port of the duplexer, and is configured to combine a preset number of sub transmit signals into one transmit signal, and divide an original receive signal into a preset number of sub receive signals;
the third power division and phase modulation module 440 is connected to the receiving port of the duplexer, and is configured to combine a preset number of sub-received signals into one received signal.
The duplexer is a different-frequency duplex radio station, has the function of isolating transmitted and received signals, ensures that the receiving and transmitting can work normally at the same time, consists of two groups of band elimination filters with different frequencies, and prevents the transmission of the local transmitted signals to a receiver, and is a low-power duplexer, such as a sound meter duplexer, a sound body wave duplexer and the like. Specifically, the power capacity boosting device is disposed in a base station signal transmission channel, where the transmission channel includes a first power division and phase modulation module 410, a second power division and phase modulation module 430, and a preset number of duplexers 420, and the reception channel includes a second power division and phase modulation module 430, a preset number of duplexers 420, and a third power division and phase modulation module 440. Further, the first power dividing and phase modulating module 410 obtains an original transmitting signal, divides the original transmitting signal into a first transmitting signal, a second transmitting signal, …, and an nth transmitting signal, the divided first transmitting signal, second transmitting signal, …, and nth transmitting signal are respectively inputted from the transmitting ports of the first duplexer, the second duplexer …, and the nth duplexer, and then outputted from the corresponding antenna ports, phase modulation is performed at the second power dividing and phase modulating module 430, and in-phase combining is completed, the original receiving signal is outputted from the second power dividing and phase modulating module 430, and then divided into a first receiving signal, a second receiving signal, …, and an nth receiving signal, and then the divided first receiving signal, second receiving signal, …, and nth receiving signal are respectively inputted from the antenna ports of the first duplexer, the second duplexer …, and the nth duplexer, and then outputted from the receiving ports, and performing phase modulation on the third power division phase modulation module 440 and completing an in-phase combining path, wherein N is an integer, and the specific numerical value is determined in advance according to the rated power of the duplexer and the base station and the first power division phase modulation module. The amplitude ratio and phase ratio between the N transmit signals is the same as the amplitude ratio and phase ratio between the N receive signals.
Further, in order to ensure that the signal is divided into multiple paths and then can be re-combined into one path of signal, after the first power division phase modulation module 410 divides the original transmission signal into N paths of sub-transmission signals, the second power division phase modulation module 430 must have N input ports to receive the N paths of sub-transmission signals, so as to perform phase modulation and combination on the N paths of sub-transmission signals. Therefore, the first power division phase modulation module 410 is the same as the second power division phase modulation module 430, and similarly, the second power division phase modulation module 430 is the same as the third power division phase modulation module 440. The predetermined number of duplexers are the same duplexer.
In particular, the transmitting channel and the receiving channel share the second power division phase modulation module 430, the first power division phase modulation module 410, the second power division phase modulation module 430, the third power division phase modulation module 440, and the predetermined number of duplexers 420 form a structure similar to a duplexer, and the transmitting and receiving of the high-power signal are realized by using a low-power duplexer.
In this embodiment, a power capacity improving apparatus is provided, where three identical power dividing and phase modulating modules and a preset number of duplexers are used to perform splitting, phase modulating, and combining on an original transmitting signal and an original receiving signal, so that a low-power capacity duplexer can be applied in a scenario of a high-power base station, the power capacity of the whole apparatus is improved, and the application range of the low-power capacity duplexer is significantly expanded.
As shown in fig. 4A, in one embodiment, the first power division phase modulation module 410 includes a power divider 410A and a phase adjuster 410B, and a signal output port of the power divider 410A is connected to an input port of the phase adjuster 410B;
the power divider 410A is configured to divide power of an original transmission signal to generate a preset number of sub transmission signals; the phase adjuster 410B is used to adjust the phase of each sub transmission signal.
Specifically, the first power division and phase modulation module 410 includes a power divider 410A and a phase adjuster 410B, and a signal output port of the power divider 410A is connected to an input port of the phase adjuster 410B. The power divider 410A can divide a signal into multiple signals, and has an input port and multiple output ports. The process of the first power division phase modulation module 410 dividing the original transmission signal into multiple sub-signals is as follows: the original transmitting signal is divided into a plurality of sub-signals by the power divider 410A and output from different output ports, the plurality of sub-signals are respectively input to the input ports of the phase adjuster 410B according to the connection relationship between the power divider 410A and the phase adjuster 410B, the phase of the sub-signals is adjusted by utilizing microstrip lines in the transmission channels corresponding to the input ports of the phase adjuster 410B, and a preset number of sub-transmitting signals with different phases are output. Specifically, the output port of the power divider 410A corresponds to any one of the input ports of the phase adjuster 410B. Further, the second power division phase modulation module 430 and the third power division phase modulation module 440 also include a power divider and a phase adjuster, and the power divider and the phase adjuster have the same connection relationship with the first power division phase modulation module, but the types of the power dividers of different power division phase modulation modules may be the same or different, and the types of the phase adjusters may be the same or different.
The phase modulation of the multi-path signal by the second power division phase modulation module 430 or the third power division phase modulation module 440 is performed, and the process of combining the multi-path signal into one path of signal output is as follows: the preset number of sub-signals are respectively input into the corresponding transmission channels from the output ports of the phase adjuster, so that the preset number of sub-signals are adjusted into sub-signals with the same phase by the phase adjuster and are output from the corresponding input ports, each path of sub-signals are respectively input into the power divider from the corresponding output port of the power divider according to the connection relation between the phase adjuster and the power divider, and the preset number of sub-signals with the same phase are combined into one path of signal output by the principle that the power divider inputs the signals from the output ports to be combined.
Specifically, for example, the power divider in the first power division phase modulation module 410 is different from the power divider in the second power division phase modulation module 430. If the power divider in the first power division and phase modulation module 410 is a wilkinson power divider, one circuit can be divided into four circuits, the corresponding phase adjuster has four input ports, and the power divider in the second power division and phase modulation module 430 is a bridge, and can combine four signals into one signal. After an original transmission signal enters the wilkinson power divider of the first power division and phase modulation module 410, the original transmission signal is divided into four paths of sub-transmission signals, and the sub-transmission signals enter the phase regulators respectively from the four input ports, enter the four duplexers respectively after being phase-modulated by the phase regulators, and enter the channels of the corresponding phase regulators in the second power division and phase modulation module 430 respectively from the port outputs of the four duplexers, so that the four paths of sub-transmission signals are adjusted into sub-transmission signals with the same phase, and then the four paths of sub-transmission signals are combined into one path of transmission signal output through the bridge in the second power division and phase modulation module 430.
As shown in fig. 5, in a specific embodiment, a case where the power boosting device includes two duplexers is taken as an example. An original transmission signal is divided into a first transmission signal TX1 and a second transmission signal TX2 after passing through a first power division phase modulation module 510, then the first transmission signal TX1 and the second transmission signal TX2 enter from transmission ports of a first duplexer 540 and a second duplexer 550 respectively, and then the first transmission signal TX1 and the second transmission signal TX2 are output from antenna ports of the first duplexer 540 and the second duplexer 550 respectively, and a second power division phase modulation module 520 phase modulates the first transmission signal TX1 and the second transmission signal TX2 and completes in-phase combining.
Further, before entering the second power division and phase modulation module 520, the first transmission signal TX1 and the second transmission signal TX2 have an amplitude ratio of 1:2, and the phase of TX1 lags behind the phase of TX2 by 50 degrees, and after entering the second power division and phase modulation module 520, the two transmission signals are combined into one signal after being modulated into signals with the same phase by the phase modulation and combination of the second power division and phase modulation module 520.
The received signal is divided into a first path of received signal RX1 and a second path of received signal RX2 after passing through the second power division phase modulation module 520, then enters through the antenna ports of the first duplexer 540 and the second duplexer 550 respectively, and is then output by the receiving ports of the first duplexer 540 and the second duplexer 550 respectively, and the third power division phase modulation module 530 phase-modulates the first path of received signal RX1 and the second path of received signal RX2 and completes in-phase combining; further, before entering the second power division phase modulation module, the amplitude ratio of the first path of received signal RX1 and the second path of received signal RX2 is 1:2, and the phase of RX1 lags behind the phase of RX2 by 50 degrees; after the two paths of received signals enter the second power dividing and phase modulating module, the two paths of received signals are subjected to in-phase combining and output under the phase modulating and combining effects of the second power dividing and phase modulating module. The amplitude ratio between the two paths of received signals is related to the phase ratio and the power division phase modulation module.
As shown in fig. 6, in a specific embodiment, the power division and phase modulation module includes a power divider and a phase adjuster, and taking the power divider as a 3dB bridge as an example, the power boosting apparatus includes: a first bridge 610, a second bridge 620, a third bridge 630, a first duplexer 640, and a second duplexer 650.
The first bridge 610, the second bridge 620 and the third bridge 630 are all 3dB bridges, the 3dB bridge is a commonly used power distribution device, and can divide a signal into two paths of signals, and the two paths of output signals of the 3dB bridge have the same amplitude and a phase difference of 90 degrees, and have a phase adjustment function, so that the power division phase modulation module can be directly realized by the 3dB bridge without adding a phase adjuster.
Specifically, the transmission signal is divided into a first transmission signal TX1 and a second transmission signal TX2 after passing through the first bridge 610, and then the first duplexer 640 and the second duplexer 650 output the signals to the second bridge 620, and the second bridge 620 phase-modulates the first transmission signal TX1 and the second transmission signal TX2 and completes in-phase combining.
Further, before the first transmit signal TX1 and the second transmit signal TX2 enter the second bridge 620, under the action of the first bridge 610, the amplitudes of the first transmit signal TX1 and the second transmit signal TX2 are identical, and the phase of TX1 lags the phase of TX2 by 90 degrees, after entering the second bridge 620, because the first bridge 610 and the second bridge 620 are the same bridge, the signal generated by the action of the first bridge 610 enters the second bridge 620, and under the opposite action of the second bridge 620, the signal becomes the same signal again, and then the second bridge 620 combines the two signals with the same phase into one signal to be output.
The received signal is divided into a first received signal RX1 and a second received signal RX2 by the second bridge 620, and then outputted to the third bridge 630 by the first duplexer 640 and the second duplexer 650, respectively, and the third bridge 630 phase-modulates the first received signal RX1 and the second received signal RX2 and completes in-phase combining.
Specifically, before the first received signal RX1 and the second received signal RX2 enter the third bridge 630, the amplitudes of the first received signal RX1 and the second received signal RX2 are consistent, and the phase of RX1 lags behind the phase of RX2 by 90 degrees; after entering the third bridge 630, because the second bridge 620 and the third bridge 630 are the same bridge, the signal generated by the action of the second bridge 620 is input into the third bridge 630, and becomes the signal with the same phase again under the opposite action of the third bridge 620, and then the third bridge 730 combines the two signals with the same phase into one signal for output.
