Description

The present invention relates to a distribution synthesizer that distributes an input signal and synthesizes the distributed signal.

When supplying a transmission signal to a transmission antenna, the process of amplifying each transmission signal distributed by the distributor, synthesizing it with a synthesizer, and inputting the combined signal to the transmission antenna is generally performed. It has been.

During the above processing, if there is a phase difference in each path from the branch point where distribution is performed to the synthesis point where synthesis is performed, power loss of the transmission signal occurs during synthesis. If the synthesizer is, for example, a hybrid type, the power loss will appear in the form of an output to the dummy load.

To solve this problem, when using a hybrid synthesizer, monitor the output to the dummy load and adjust the phase shift amount of the phase shifter inserted in each path so that the output is minimized. The method is known (see Patent Documents 1 to 4).

Then, as a general search method for searching for the amount of phase shift that minimizes the output, the phase shifter is made to perform phase shift little by little, and the output is increased or decreased before and after the phase shift is executed. A method of searching for the minimum amount of phase shift can be considered.

However, when the general search method described in the section of background technology is used, when the loss signal representing the output is minute, the increase / decrease in the output due to the phase shift of the minute phase shift amount is small. It is difficult to find the amount of phase shift that minimizes the output.

<First mobile phone>
The first embodiment is an embodiment relating to a distribution synthesizer that distributes an input signal, amplifies each distributed signal, and synthesizes each amplified signal.
[Configuration and operation]
FIG. 1 is a conceptual diagram showing a configuration of a distribution / synthesis device 101, which is an example of the distribution / synthesis device of the first embodiment.

The distribution synthesizer 101 includes a distributor 111, a phase shifter 121, amplifiers 131 and 132, a hybrid synthesizer 141, a directional coupler 161 and a resistor 151.

The distributor 111 outputs the distributed signal obtained by distributing the input signal input to the terminal a to the terminals b and c.

The phase shifter 121 shifts the phase of the distribution signal input from the terminal b according to the instruction from the control unit 171 and outputs the phase shift distribution signal, which is the distribution signal after the phase shift, to the amplifier 131.

The amplifier 131 outputs the amplified phase shift distribution signal obtained by amplifying the phase shift distribution signal input from the phase shifter 121 to the terminal d of the hybrid type synthesizer 141.

The amplifier 132 outputs an amplified distribution signal obtained by amplifying the distribution signal input from the terminal c of the distributor 111 to the terminal e of the hybrid synthesizer 141. The amplification factor of the amplifier 132 is equal to that of the amplifier 131.

The hybrid type synthesizer 141 outputs a post-synthesis signal synthesized from the amplified phase shift distribution signal input to the terminal d and the amplified and distributed signal input to the terminal e to the terminal f. The hybrid synthesizer 141 also outputs a loss signal generated by the phase difference between the amplified phase shift distribution signal and the amplified distribution signal to the terminal g. The signal level of the loss signal represents the power loss that occurs when the amplified phase shift distribution signal and the amplification distribution signal are combined by the hybrid synthesizer 141. Here, the signal level is a value representing any of electric power, voltage, and current.

The loss signal is guided to ground via the resistor 151.

The directional coupler 161 separates the partial loss signal that is a part of the loss signal and sends it to the control unit 171. The signal level of the partial loss signal is proportional to the amplitude of the loss signal. Therefore, the signal level represents the power loss that occurs when the amplified phase shift distribution signal and the amplification distribution signal are combined by the hybrid synthesizer 141.

The control unit 171 detects the signal level of the partial loss signal sent from the directional coupler 161.

The control unit 171 also controls the phase shift amount of the phase shift distribution signal with respect to the distribution signal to the phase shifter 121 by sending control information to the phase shifter 121.

The control unit 171 derives the phase shift amount that minimizes the power of the loss signal by the method described later by the control. Then, the control unit 171 causes the phase shifter 121 to perform the phase shift of the derived phase shift amount.

FIG. 2 shows the relationship between the phase difference between the amplified phase shift distribution signal input to the terminal d of the hybrid synthesizer 141 and the amplified phase distribution signal input to the terminal e and the signal level of the partial loss signal. It is an image diagram to represent. The signal level on the vertical axis shown in FIG. 2 is a value representing any of power, voltage, and current of the partial loss signal. The phase difference on the horizontal axis shown in FIG. 2 is the phase difference between the amplified phase shift distribution signal and the amplified phase distribution signal. Here, in the following description, when the phase of the phase shift distribution signal is ahead of the phase of the distribution signal, it is considered that the phase is advanced.

The signal level has a shape symmetrical with respect to the vertical axis representing 0 phase difference. The reason for such a shape is that the signal level depends on the absolute value of the phase difference.

The signal level is minimized when the phase difference is 0. Then, the signal level when the phase difference is provided in the direction in which the phase advances by a predetermined phase difference from the phase difference 0 is equal to the signal level when the same phase difference is provided in the direction in which the phase is delayed. Further, the slope of the increase in the signal level due to the increase in the phase difference increases with the increase in the phase difference.

FIG. 3 is a diagram for explaining a method of obtaining a phase shift amount at which the phase difference becomes 0 when the relationship between the phase difference and the signal level is shown in FIG. Here, the phase shift amount is the phase shift amount of the distribution signal performed by the phase shifter 121 shown in FIG. 1 from the zero point preset in the phase shifter 121. The phase shift amount has a positive direction in which the phase of the phase shift distribution signal is advanced with respect to the phase of the distribution signal.

There are two phase shift amounts, the phase shift amount Φ _L and the phase shift amount Φ H, at which the signal level reaches the threshold value P _th2 . The phase shift amount Φ _L is a case where the phase of the phase shift distribution signal is delayed with respect to the phase of the distribution signal. Further, the phase shift amount Φ _H is a case where the phase of the phase shift distribution signal is advanced with respect to the phase of the distribution signal.

As described above, the signal level when a predetermined phase difference is provided in the positive direction from the phase difference 0 is equal to the signal level when the same phase difference is provided in the negative direction. Therefore, the average of the phase shift amount Φ _L and the phase shift amount Φ _H is the phase shift amount Φ ₀ , which is the phase shift amount at which the phase difference becomes 0. That is, the phase shift amount Φ _{0 at which the phase difference becomes 0 is} Φ ₀ = (Φ _L + Φ _H ) / 2.

Therefore, the phase shift amount Φ ₀ can be obtained by finding the phase shift amount Φ _L and the phase shift amount Φ _H by searching.

Although FIG. 1 shows a case where the phase shifter 121 is installed outside the amplifier 131, the phase shifter 121 may be installed on the input side inside the amplifier 131.
[Processing flow example]
FIG. 4 shows a process performed by the control unit 171 shown in FIG. 1 for deriving the phase shift amount Φ ₀ , which is the phase shift amount of 0, and causing the phase shifter 121 to execute the phase shift of the phase shift amount Φ ₀ . It is a conceptual diagram which shows the processing flow example of.

The control unit 171 starts the process shown in FIG. 4, for example, by inputting start information from the outside.

Then, the control unit 171 sets the integration number i, which represents the integration execution number of the phase shift, to 0 as the process of S101. Further, the control unit 171 sets the integrated phase shift amount Φ _i to 0 as the same process. Here, the integrated phase shift amount Φ _i is an integrated value of the phase shift amount when the phase shift of the integration number i is executed. It is assumed that the control unit 171 includes a storage unit that stores the total number of times i, the integrated phase shift amount Φ _i , and the phase shift amounts Φ _L , Φ _H , Φ ₀ , and the like.

Next, the control unit 171 increases the number of integrations i by 1 as the process of S102.

Then, the control unit 171 further causes the phase shifter 121 to shift the phase in the positive direction by the phase shift amount ΔΦ as the same process. Here, the phase shift amount ΔΦ is a preset value as the phase shift amount in which the phase shifter 121 shifts the phase at one time. The phase shift amount ΔΦ is a sufficiently small value with respect to each of the phase shift amounts Φ _L , Φ ₀ , and Φ _H. When the control unit 171 causes the phase shifter 121 to perform the phase shift, the control unit 121 sends a control signal for causing the phase shifter 121 to perform the phase shift, and then the phase shifter 121 shifts the phase by the control signal. Shall wait for a time to complete the execution of.

Then, the control unit 171 further increases the integrated phase shift amount Φ _i by ΔΦ in the same process.

Next, as the process of S103, the control unit 171 determines whether the absolute value of the difference between the signal level Pi and the signal level _{Pi -1} is larger than the threshold value P _th1 . Here, the signal level Pi is a value representing the above-mentioned signal level after the phase shift of the integration number _i is performed. Further, the threshold value P _th1 is a threshold value for the absolute value of the difference between the signal level _Pi and the signal level _Pi-1 preset for the processing of S103.

When the determination result by the process of S103 is no, the control unit 171 performs the process of S104.

On the other hand, if the determination result by the process of S103 is yes, the control unit 171 performs the process of S102 again.

If the difference between the signal level _Pi and the signal level _Pi-1 is very small, the determination result related to the determination of the processing of S104 described below may be inaccurate. In order to avoid the possibility, the process of S103 is performed to shift the position of the integrated phase shift amount _Φi for determining S104 to a position where the difference is large to some extent.

When the processing of S104 is performed, the control unit 171 determines whether the signal level Pi is larger than the signal level _{Pi -1} as the processing. When the signal level P _i is larger than the signal level P _i-1 , it means that the signal level is increased by performing the phase shift of + ΔΦ once from the number of integrations i-1.

[effect]
In the distribution synthesizer of the present embodiment, the control unit obtains the phase shift amount of the demultiplexing phase shift amplification signal at which the signal level of the signal representing the power loss from the hybrid type synthesizer becomes a predetermined value. Here, the demultiplexing phase shift amplification signal is a demultiplexing amplification signal obtained by amplifying a signal that has undergone phase shift by a phase shifter.

As described in the section of the problem to be solved by the invention, it may be difficult when the signal level is low. However, when the control unit performs the processing, the threshold value can be set sufficiently large, so that there is little adverse effect due to the small signal level. Therefore, the distribution synthesizer can perform phase shift that can suppress the lost power even when the signal level of the signal representing the lost power is small.
<Second embodiment>
The second embodiment is an embodiment relating to a distribution synthesizer including a plurality of hybrid synthesizers.
[Configuration and operation]
FIG. 5 is a conceptual diagram showing the configuration of the distribution / synthesis device 101, which is an example of the distribution / synthesis device of the second embodiment.

The distribution synthesizer 101 includes a distributor 111, n-1 phase shifters 121 to 12 (n-1), and n amplifiers 131 to 13n. The distribution synthesizer 101 further includes hybrid synthesizers 141 to 14 (n-1), which are n-1 hybrid synthesizers, and resistors 151 to 15 (n-1), which are n-1 resistors. And a control unit 171.

The distributor 111 distributes the input signal to n distribution signals.

Each of the phase shifters 121 to 12 (n-1) (each phase shifter) shifts the phase to the input distribution signal according to the control information from the control unit 171 and is the distribution signal after the phase shift. The phase shift distribution signal is output to the corresponding amplifier 131 to 13 (n-1).

On the other hand, the distribution signal is directly input to the amplifier 13n from the distributor 111.

Each of the amplifiers 131 to 13 (n-1) (each amplifier) amplifies the input signal, and the amplified signal, which is the amplified signal, is combined with the corresponding hybrid type synthesizer (hybrid type synthesizer 141 to 14). Output to one of the input terminals (upper side in FIG. 5) of each of (n-1).

The amplifier 13n amplifies the input signal, and outputs the amplified signal, which is the amplified signal, to the input terminal of the other side (lower side in FIG. 5) of the hybrid type synthesizer 14 (n-1).

Each of the hybrid type synthesizers 142 to 14 (n-1) is a composite signal obtained by synthesizing two input signals from one (upper side in FIG. 5) output terminal of the hybrid type synthesizers 141 to 14 (n-1). -2) Output to the other (lower side in FIG. 5) input terminal.

On the other hand, the hybrid type synthesizer 141 outputs the synthesized signal obtained by synthesizing the two input signals to the antenna 181.

A loss signal is output from the output terminal of the other side (lower side in FIG. 5) of each hybrid type synthesizer. The loss signal is due to the phase difference between the signal input to the input terminal of one (upper side in FIG. 5) and the signal input to the input terminal of the other (lower side in FIG. 5) of each hybrid synthesizer. It happens.

The loss signal output from each hybrid is guided to ground through each corresponding resistance (each of the resistances 151 to 15 (n-1)).

Each of the directional couplers 161 to 16 (n-1) (each directional coupler) sends each of the partial loss signals obtained by branching a part of each of the loss signals to the control unit 171. The signal level of the partial loss signal is proportional to the signal level of the loss signal.

The control unit 171 sends a control signal for causing each phase shifter to perform phase shift from the signal level of the partial loss signal input from each directional coupler. The control unit 171 causes each phase shifter to perform phase shift so that the power of each loss signal is minimized by sending the control signal.

In that case, the control unit 171 first causes the phase shifter 12 (n-1) to shift the phase so that the signal level of the partial loss signal from the hybrid synthesizer 14 (n-1) is minimized. .. The signal level of the partial loss signal is proportional to the signal level of the loss signal. Therefore, the power of the loss signal can be minimized by performing the phase shift so that the signal level of the partial loss signal is minimized.

Next, the control unit 171 causes the phase shifter 12 (n-2) to perform phase shift so that the partial loss signal from the hybrid synthesizer 14 (n-2) is minimized.

In this way, the control unit 171 causes the phase shifter 121 to perform phase shift in the same manner.

The control unit 171 causes the phase shift in each of the phase shifters to be performed by the same method as that described in the first embodiment.

As described above, the control unit 171 adjusts the phase shift amount of each phase shifter so that each loss signal output from each hybrid type combiner is minimized.

Although FIG. 5 shows a case where each phase shifter is installed outside the amplifier, each phase shifter may be installed on the input side inside each corresponding phase shifter.
[effect]
The distribution / synthesis device of the present embodiment adjusts the phase of each distribution signal by the same method as the method of the first embodiment in the distribution / synthesis device that amplifies each distribution signal that distributes the input signal into three or more. Therefore, the distribution / synthesis device has the same effect as that of the first embodiment in the distribution / synthesis device that distributes, amplifies, and synthesizes the input signal into three or more.
<Third embodiment>
The above explanation has described an example in which a hybrid synthesizer is used as the synthesizer. However, a transformer type synthesizer may be used. Next, a case where a transformer type is used for the synthesizer will be described.
[Configuration and operation]
FIG. 6 is a conceptual diagram showing the configuration of the distribution synthesizer 102, which is an example of the distribution synthesis device of the third embodiment using the transformer type as the synthesizer.

The distribution synthesizer 101 includes a distributor 111, a phase shifter 121, amplifiers 131 and 132, a transformer type synthesizer 142a, and a directional coupler 162a.

The distributor 111 distributes the input signal input to the terminal a, and outputs the distributed signal, which is the input signal after distribution, to the terminals b and c.

The phase shifter 121 shifts the phase of the distribution signal input from the terminal b according to the instruction from the control unit 172, and outputs the phase shift distribution signal, which is the signal after the phase shift, to the amplifier 131.

The amplifier 131 outputs the amplified phase shift distribution signal obtained by amplifying the phase shift distribution signal input from the phase shifter 121 to the terminal d of the transformer type synthesizer 142a.

The amplifier 132 outputs the amplified distribution signal obtained by amplifying the distribution signal input from the terminal c of the distributor 111 to the terminal e of the transformer type synthesizer 142a. The amplification factor of the amplifier 132 is equal to that of the amplifier 131.

The transformer type synthesizer 142a outputs the combined signal synthesized from the amplified phase shift distribution signal input to the terminal d and the amplified and distributed signal input to the terminal e to the terminal f.

The transformer type synthesizer 142a also outputs the reflected signal of the amplified phase shift distribution signal from the terminal d to the output terminal of the amplifier 131.

The reflected signal is a loss signal representing the power loss during synthesis in the transformer type synthesizer 142a.

The reflected signal is generated according to the magnitude of the phase difference when there is a phase difference between the amplified phase distribution signal and the amplification distribution signal. When the phase difference is 0, the signal level of the reflected signal is minimized.

The directional coupler 162a outputs a partially reflected signal that is a part of the reflected signal to the control unit 172. The signal level of the partially reflected signal is proportional to the signal level of the reflected signal. The signal level is one of voltage, current and power. The signal level of the partially reflected signal represents the power of the loss signal.

The control unit 172 causes the phase shifter 121 to shift the phase so that the signal level of the partially reflected signal input from the directional coupler 162a is minimized.

The method of causing the phase shifter 121 to shift the phase so that the control unit 172 minimizes the signal level of the partially reflected signal is such that the control unit 171 shown in FIG. 1 minimizes the loss signal described above. This is the same as the method of causing the phase transfer device 121 to perform phase transfer.

Although FIG. 6 shows a case where the directional directional coupler 162a is provided outside the amplification unit 131, the amplification unit 131 may include a reflection meter. In that case, the phase shifter 121 may be phased so that the signal level of the output signal from the reflection meter is minimized.
[effect]
In the distribution synthesizer of the present embodiment, when a transformer type synthesizer is used, the phase shift of the distribution amplification synthesis signal that minimizes the signal level of the reflected signal representing the power loss at the time of synthesis is performed. The distribution synthesis apparatus performs the phase transfer by the same method as the phase transfer method in the first embodiment and the second embodiment. Therefore, the distribution synthesizer can perform phase shift to minimize the power of the loss signal even when the signal level of the signal representing the power loss at the time of synthesis is small when the transformer type synthesizer is used.

In the above description of the embodiment, the case where the processing performed for each distributed signal is amplification by an amplifier has been described. However, the process may be something other than amplification. Further, in that case, the processing contents of each processing may be the same.

FIG. 7 is a conceptual diagram showing the configuration of the distribution / synthesis device 101x, which is the minimum configuration of the distribution / synthesis device of the embodiment.

The distribution synthesis device 101x includes a distribution unit 111x, a phase shift unit 121x, a synthesis unit 141x, and a control unit 171x.

The distribution unit 111x distributes the first distribution signal and the second distribution signal from the input signal.

The phase shift unit 121x performs phase shift of at least one of the first distribution signal and the second distribution signal.

The synthesizing unit 141x synthesizes the first distributed signal subjected to the first processing and the second distributed signal subjected to the second processing.

The control unit 171x derives a first phase shift amount that minimizes a value representing at least one of power, voltage, and current related to the loss that occurs during the synthesis. The control unit 171x derives the derivation of the second phase shift amount and the third phase shift amount adjacent to each other with the first phase shift amount in between, and the second phase shift amount is equal to a predetermined threshold value. The first phase shift amount is derived from the phase shift amount and the third phase shift amount. Then, the control unit 171x causes the phase shifter to perform the phase shift according to the first phase shift amount.

As described in the section of the problem to be solved by the invention, it may be difficult to search by the general search method described in the section of background technology when the value is small. However, since the distribution synthesizer 101x can set the threshold value to a sufficiently large value, there is little adverse effect due to the small value. Therefore, the distribution synthesizer 101x can perform phase shift that can suppress the loss even when the value is small.

Therefore, the distribution synthesizer 101x exhibits the effects described in the section [Effects of the Invention] by the above configuration.
