Detailed Description
In radio frequency power control, it is often involved in outputting or inputting radio frequency power between different channels. For example, the electronic device is connected with directional antennas in different directions, and signals can be hopefully transmitted in different directions in a time-sharing way so as to realize low-cost coverage; alternatively, the electronic device may need to receive incoming signals in an indeterminate direction, switch between different directional receive antennas to take advantage of the directional antenna gain being higher than the omni-directional antenna gain, etc.
In the related art, the output of radio frequency power between two or more channels is achieved by a radio frequency switch. The scheme has the following defects: the radio frequency power can only be output in a time-sharing way among different channels, and when one channel is selected to output the radio frequency power, other channels are not output by the radio frequency power; this is not possible in cases where a certain power allocation between different channels is desired.
Based on this, in embodiments of the present application, a phase shift value is configured for each phase shifter in the power control network; wherein the power control network comprises at least one power control module; each of the at least one power control module comprises a power divider, a phase shifter and a bridge; the input end of the power divider is used for inputting radio frequency power, the first output end of the power divider is connected to the first input end of the bridge through the phase shifter, and the second output end of the power divider is connected to the second input end of the bridge; the configured phase shift value is used for controlling the radio frequency power output by two output channels of the bridge connected with the corresponding phase shifter. In the scheme, by configuring the phase shift value for each phase shifter in the power control network, the two paths of output channels of the bridge connected with the corresponding phase shifter can be controlled to output radio frequency power simultaneously, the magnitude of the radio frequency power output by the corresponding two paths of output channels can be controlled, and the flexibility of radio frequency power control is improved.
The present application is described in further detail below with reference to the accompanying drawings and examples.
The embodiment of the application provides a power control method which is applied to a processor or electronic equipment comprising a power control network. The power control method is to perform power control for a power control network, referring to fig. 1, the method includes:
Step 101: a phase shift value is configured for each phase shifter in the power control network.
Wherein the power control network comprises at least one power control module; each of the at least one power control module comprises a power divider, a phase shifter and a bridge; the input end of the power divider is used for inputting radio frequency power, the first output end of the power divider is connected to the first input end of the bridge through the phase shifter, and the second output end of the power divider is connected to the second input end of the bridge;
the configured phase shift value is used for controlling the radio frequency power output by two output channels of the bridge connected with the corresponding phase shifter.
Here, a corresponding phase shift value is configured for each phase shifter in the power control network. It should be noted that the power control network may include one power control module, or may include at least two cascaded power control modules. When at least two cascaded power control modules are included in the power control network, the phase shift values configured for each phase shifter in the power control network may be the same or different. The corresponding phase shift value of each phase shifter is determined by the number of channels needing to output radio frequency power and the radio frequency power of each channel of output channel.
Each power control module in the power control network includes at least a power divider, a phase shifter, and a bridge. The power divider is used for dividing the input radio frequency power into two paths of equal radio frequency power for output, that is, the power divider is a two-way power divider in the embodiment of the application. The phase shifter is used for controlling the radio frequency power output by two paths of output channels of the correspondingly connected bridge based on the configured phase shift value; the phase shifter may be an analog phase shifter or a digital phase shifter. The bridge in each power control module may be a three decibel (dB) bridge, and the 3dB bridge may have the function of co-frequency combining, which may also be referred to as a co-frequency combiner.
In one embodiment, the phase shifter is a digital phase shifter.
Here, the phase shifters in the power control network are all digital phase shifters. Wherein the digital phase shifter supports configuration or modification of the phase shift value by a computer program or computer instructions, and the switching speed of the phase shift value of the phase shifter is less than 1 microsecond. Therefore, the phase shift value of the phase shifter can be quickly and accurately configured or changed, so that the radio frequency power output by each output channel of the bridge connected with the phase shifter can be quickly and flexibly controlled.
As shown in fig. 2, the power control module 2 includes a power divider 21, a phase shifter 22, and a bridge 23; the power divider 21 is a two-power divider and comprises an input end, a first output end and a second output end; the bridge 23 includes a first input terminal, a second input terminal, a first output channel, and a second output channel.
The input end of the power divider 21 is used for inputting radio frequency power, the first output end of the power divider 21 is connected with the input end of the phase shifter 22, and the output end of the phase shifter 22 is connected with the first input end of the bridge 23; a second output of the power divider 21 is directly connected to a second input of the bridge 23. The first output channel of the bridge 23 is the first output channel of the power control module 2 (OUT 1 in fig. 2), and the second output channel of the bridge 23 is the second output channel of the power control module 2 (OUT 2 in fig. 2).
The phase shift value configured for the phase shifter 22 in the power control module 2 is used for controlling the radio frequency power output by two output channels of the bridge 23 connected with the phase shifter 22. That is, the phase shifter 22 controls the bridge 23 to output the radio frequency power which is not zero only through one of the output channels based on the configured phase shift value; alternatively, phase shifter 22 controls the two output channels of bridge 23 to simultaneously output radio frequency power that is not zero based on the configured phase shift values.
The working principle of the power control module 2 is as follows:
in the case of inputting radio frequency power to the power control module 2, the radio frequency power is input from the input terminal of the power divider 21; the power divider 21 outputs a first radio frequency power at a first output terminal and a second radio frequency power at a second output terminal based on the input radio frequency power; the phase of the first radio frequency power is adjusted by the phase shifter 22 and then the first radio frequency power is input to a first input end of the bridge 23, and the second radio frequency power is directly input to a second input end of the bridge 23; the bridge 23 outputs a third radio frequency power at a first output channel (OUT 1) of the bridge 23 and a fourth radio frequency power at a second output channel (OUT 2) of the bridge 23 based on the input first radio frequency power and the second radio frequency power.
It should be noted that, the third rf power or the fourth rf power output by the bridge 23 is zero, or neither the third rf power nor the fourth rf power is zero.
In an ideal case, i.e. without considering the path loss and the insertion loss of the device, the sum of the first rf power and the second rf power input to the bridge 23 is equal to the sum of the third rf power and the fourth rf power output from the bridge 23.
In one embodiment, the phase shift value is configured to be equal to an odd multiple of 90, and the bridge connected to the corresponding phase shifter is controlled to output radio frequency power through only one output channel.
Here, the phase shift value of the phase shifter in any power control module is configured to be odd multiple of 90, so that the radio frequency power output by one output channel of the bridge connected with the phase shifter can be controlled to be zero, and the radio frequency power output by the other output channel is not zero, so that the power control module outputs the radio frequency power which is not zero only through one output channel. Therefore, switching output of the radio frequency power among different channels can be realized, and flexible switching of the radio frequency power can be realized.
For example, in the case where the phase shift value of the phase shifter 22 is configured to be positive 90 degrees (+90°), the first radio frequency power and the second radio frequency power of the input bridge 23 are completely cancelled by the power due to the opposite phase (180 degrees out of phase) in the second output channel of the bridge 23, and the power is superimposed by the same phase in the first output channel of the bridge 23, so that, in an ideal case, the fourth radio frequency power output by the second output channel of the bridge 23 is zero, and the third radio frequency power output by the first output channel of the bridge 23 is equal to the sum of the first radio frequency power and the second radio frequency power. That is, the radio frequency power input to the power divider 21 is output from the first output channel (OUT 1) of the bridge 23.
For another example, in the case where the phase shift value of the phase shifter 22 is configured to +270°, the first rf power and the second rf power of the input bridge 23 are completely cancelled by the opposite phases of the first output channel of the bridge 23, and the second output channel of the bridge 23 is superimposed by the same phases of the power, so that, in an ideal case, the third rf power output by the first output channel of the bridge 23 is zero and the fourth rf power output by the second output channel of the bridge 23 is equal to the sum of the first rf power and the second rf power. That is, the radio frequency power input to the power divider 21 is output from the second output channel (OUT 2) of the bridge 23.
For another example, in the case where the phase shift value of the phase shifter 22 is configured to be minus 90 degrees (-90 °), the first rf power and the second rf power of the input bridge 23 are completely cancelled by the opposite phase in the first output channel of the bridge 23 and the power is superimposed by the same phase in the second output channel of the bridge 23, so that, in an ideal case, the third rf power output from the first output channel of the bridge 23 is zero and the fourth rf power output from the second output channel of the bridge 23 is equal to the sum of the first rf power and the second rf power. That is, the radio frequency power input to the power divider 21 is output from the second output channel (OUT 2) of the bridge 23.
For another example, in the case where the phase shift value of the phase shifter 22 is configured to be-270 °, the first rf power and the second rf power of the input bridge 23 are completely cancelled by the opposite phase in the second output channel of the bridge 23, and the power is superimposed by the same phase in the first output channel of the bridge 23, so that in an ideal case, the fourth rf power output by the second output channel of the bridge 23 is zero, and the third rf power output by the first output channel of the bridge 23 is equal to the sum of the first rf power and the second rf power. That is, the radio frequency power input to the power divider 21 is output from the first output channel (OUT 1) of the bridge 23.
In one embodiment, the phase shift value is not equal to an odd multiple of 90, and the phase shift value is used for controlling two output channels of the bridge connected with the corresponding phase shifter to output radio frequency power simultaneously.
Here, the phase shift value of the phase shifter in any power control module is configured to be not equal to odd multiple of 90, so that two paths of output channels of the bridge connected with the phase shifter can be controlled to simultaneously output radio frequency power which is not zero, and the power control module can simultaneously output radio frequency power through the two paths of output channels. Therefore, different output channels can be controlled according to actual demands to simultaneously output the same or different radio frequency power, and the flexibility and diversity of radio frequency power control can be improved to meet the demands of users.
For example, in the case where the phase shift value of the phase shifter 22 is configured to be (+90+m) degrees and M is not 0, the first rf power and the second rf power of the input bridge 23 are not completely cancelled by the phase difference of 180 degrees in the second output channel of the bridge 23, and therefore, the third rf power output by the first output channel of the bridge 23 is not zero and the fourth rf power output by the second output channel of the bridge 23 is also not zero. That is, the radio frequency power input to the power divider 21 is simultaneously output from the first output channel and the second output channel of the bridge 23. Wherein, (+90+M) is greater than or equal to 0 and less than or equal to 360.
For another example, in the case where the phase shift value of the phase shifter 22 is configured to (-90+m) degrees and M is not 0, the first rf power and the second rf power of the input bridge 23 are not completely cancelled by the phase difference of 180 degrees in the first output channel of the bridge 23, and therefore, the third rf power output by the first output channel of the bridge 23 is not zero and the fourth rf power output by the second output channel of the bridge 23 is not zero. That is, the radio frequency power input to the power divider 21 is simultaneously output from the first output channel and the second output channel of the bridge 23. Wherein (-90+M) is greater than or equal to 0 and less than or equal to 360.
In order to obtain enough output channels for switching selection of radio frequency power, in an embodiment, the power control network includes N cascaded power control modules, where N is an integer greater than or equal to 2.
Here, in the case where the power control network includes N cascaded power control modules, one path of output channel of the power control module of the front stage is connected to the input of the power control module of the rear stage in every two cascaded power control modules.
In the case where N is greater than or equal to 3, the number of power control modules in the same stage may be 1 or 2. When the number of the power control modules of the same stage is 1, only one output channel of the power control module of the front stage is connected with the power control module of the rear stage; when the number of the power control modules of the same stage is 2, each output channel of the power control module of the front stage is correspondingly connected with the power control module of the rear stage.
For example, in case N is equal to 3, the power control network may include 3 stages of power control modules connected in a cascade manner. At this time, the number of the power control modules of each stage is 1, and only one output channel of the power control module of the front stage is connected with the power control module of the rear stage in every two cascaded power control modules.
For another example, in the case where N is equal to 3, the power control network may also include 2 stages of power control modules connected in a cascade manner. The first stage power control module has only one power control module, and the second stage power control module comprises two power control modules. At this time, each output channel of the first-stage power control module is correspondingly connected with a second-stage power control module.
It should be noted that, when the power control network includes N cascaded power control modules, the power control network includes n+1 output channels. In practical application, the phase shift value of the phase shifter in each power control module in the N power control modules can be configured according to the number of channels for outputting radio frequency power and the magnitude of radio frequency power of each output channel. The working principles of the N power control modules are described above with reference to the working principles of the power control module 2, and are not repeated here.
The power control method in the embodiments of the present application will be described in detail below by taking an example in which the power control network includes one or two power control modules.
Application example one
When the power control network comprises one power control module, as shown in fig. 2, the power control network comprises a power control module 2. The phase shifter 22 in the power control network is configured with a phase shift value such that the power control network outputs radio frequency power that is not zero only through one of the output channels, or simultaneously outputs radio frequency power that is not zero through both of the output channels.
In one embodiment, where the phase shift value of phase shifter 22 is configured to be an odd multiple of 90 °, the power control network outputs a radio frequency power other than zero through OUT1 or OUT 2.
As described above, in the case where the phase shift value of the phase shifter 22 is configured to +90°, the radio frequency power input to the power divider 21 is output from the first output channel (OUT 1) of the bridge 23, and at this time, the power control network outputs only the radio frequency power that is not zero through OUT 1.
In the case where the phase shift value of the phase shifter 22 is configured to +270°, the radio frequency power input to the power divider 21 is output from the second output channel (OUT 2) of the bridge 23, and at this time, the power control network outputs only the radio frequency power which is not zero through OUT 2.
In the case where the phase shift value of the phase shifter 22 is configured to-90 °, the radio frequency power input to the power divider 21 is output from the second output channel of the bridge 23, and at this time, the power control network outputs only the radio frequency power which is not zero through OUT 2.
In the case where the phase shift value of the phase shifter 22 is configured to-270 °, the radio frequency power input to the power divider 21 is output from the first output channel (OUT 1) of the bridge 23, and at this time, the power control network outputs only the radio frequency power that is not zero through OUT 1.
In one embodiment, where the phase shift value of phase shifter 22 is configured to be an odd multiple of 90 °, the power control network outputs non-zero radio frequency power through two output channels (OUT 1 and OUT 2).
As described above, in the case where the phase shift value of the phase shifter 22 is configured to (+90+m) degrees and M is not 0, the radio frequency power input to the power divider 21 is simultaneously output from the first output channel and the second output channel of the bridge 23, and at this time, the power control network simultaneously outputs the radio frequency power other than zero through OUT1 and OUT 2. Wherein, (+90+M) is greater than or equal to 0 and less than or equal to 360.
In the case where the phase shift value of the phase shifter 22 is configured to (-90+m) degrees and M is not 0, the radio frequency power input to the power divider 21 is simultaneously output from the first output channel and the second output channel of the bridge 23, and at this time, the power control network simultaneously outputs the radio frequency power which is not zero through OUT1 and OUT 2. Wherein (-90+M) is greater than or equal to 0 and less than or equal to 360.
Application example two
When the power control network includes two power control modules, as shown in fig. 3, the power control network includes a first power control module 31 and a second power control module 32 in cascade, the first power control module 31 includes a first power divider, a first phase shifter, and a first bridge, and the second power control module 32 includes a second power divider, a second phase shifter, and a second bridge.
The input end of the first power divider is used for inputting radio frequency power, the first output end of the first power divider is connected with the input end of the first phase shifter, and the output end of the first phase shifter is connected with the first input end of the first bridge; the second output end of the first power divider is directly connected with the second input end of the first bridge. The second output channel of the first bridge is the third output channel of the power control network (OUT 3 in fig. 3).
The first output channel of the first bridge is connected with the input end of the second power divider, the first output end of the second power divider is directly connected with the first input end of the second bridge, the second output end of the second power divider is connected with the input end of the second phase shifter, and the output end of the second phase shifter is connected with the second input end of the second bridge; the first output channel of the second bridge is the first output channel of the power control network (OUT 1 in fig. 3) and the second output channel of the second bridge is the second output channel of the power control network (OUT 2 in fig. 3).
The power control network in fig. 3 operates as follows:
in the case of inputting radio frequency power to the power control network, the radio frequency power is input from the input terminal of the first power divider in the first power control module 31; the first power divider outputs fifth radio frequency power at a first output end and outputs sixth radio frequency power at a second output end based on the input radio frequency power; the fifth radio frequency power is input to the first input end of the first bridge after the phase of the fifth radio frequency power is adjusted by the first phase shifter, and the sixth radio frequency power is directly input to the second input end of the first bridge; the first bridge outputs a seventh radio frequency power at a first output channel of the first bridge and outputs an eighth radio frequency power at a second output channel of the first bridge based on the fifth radio frequency power and the sixth radio frequency power. The eighth radio frequency power is the radio frequency power output by the third output channel (OUT 3) of the power control network.
The seventh radio frequency power output by the first output channel of the first bridge is input to the input end of the second power divider in the second power control module 32, the second power divider outputs the ninth radio frequency power at the first output end and the tenth radio frequency power at the second output end based on the input seventh radio frequency power; the ninth radio frequency power output by the second power divider is directly input to the first input end of the second bridge, and the tenth radio frequency power output by the second power divider is input to the second input end of the second bridge after the phase of the tenth radio frequency power is adjusted by the second phase shifter; the second bridge outputs eleventh radio frequency power at a first output channel (OUT 1) of the second bridge and twelfth radio frequency power at a second output channel (OUT 2) of the second bridge based on the ninth radio frequency power and tenth radio frequency power inputted.
It should be noted that, the seventh rf power or the eighth rf power output by the first bridge is zero, or neither the seventh rf power nor the eighth rf power is zero. In an ideal case, the sum of the fifth rf power and the sixth rf power input to the first bridge is equal to the sum of the seventh rf power and the eighth rf power output from the first bridge.
Either the eleventh or twelfth rf power output by the second bridge is zero, or neither the eleventh nor twelfth rf power is zero. In an ideal case, the sum of the ninth rf power and the tenth rf power input to the second bridge is equal to the sum of the eleventh rf power and the twelfth rf power output from the second bridge.
In an embodiment, the power control network outputs radio frequency power through OUT1, OUT2 or OU3 that is not zero, with the phase shift values of the first and second phase shifters each configured as an odd multiple of 90 °.
For example, in the case where the phase shift values of the first phase shifter and the second phase shifter are both configured to +90°, the fifth radio frequency power and the sixth radio frequency power inputted to the first bridge are completely cancelled by the power due to the opposite phases in the second output channel (OUT 3) of the first bridge, and the power is superimposed by the same phases in the first output channel (OUT 3) of the first bridge, so that, in an ideal case, the eighth radio frequency power outputted by the second output channel (OUT 3) of the first bridge is zero, and the seventh radio frequency power outputted by the first output channel of the first bridge is equal to the sum of the fifth radio frequency power and the sixth radio frequency power. Similarly, the ninth rf power and the tenth rf power input to the second bridge are completely offset by the opposite phases in the first output channel of the second bridge, and the powers are superimposed by the same phases in the second output channel of the second bridge, so that in an ideal case, the eleventh rf power output by the first output channel (OUT 1) of the second bridge is zero, and the twelfth rf power output by the second output channel (OUT 2) of the second bridge is equal to the sum of the ninth rf power and the tenth rf power.
That is, the radio frequency power input to the first power divider is input to the second power divider from the first output channel of the first bridge, and the radio frequency power input to the second power divider is output from the second output channel of the second bridge. At this time, the radio frequency power input to the power control network is output only at the second output channel (OUT 2) of the second bridge, i.e., the power control network outputs radio frequency power which is not zero only through OUT 2.
For example, in the case where the phase shift value of the first phase shifter is configured to be-90 °, the fifth rf power and the sixth rf power inputted by the first bridge are completely cancelled by the power due to the opposite phase in the first output channel of the first bridge, and the power is superimposed due to the same phase in the second output channel (OUT 3) of the first bridge, so that in an ideal case, the eighth rf power outputted by the first output channel of the first bridge is zero, and the seventh rf power outputted by the second output channel (OUT 3) of the first bridge is equal to the sum of the fifth rf power and the sixth rf power. Because the eighth radio frequency power output by the first output channel of the first bridge is zero, the radio frequency power input into the second bridge is zero, and at this time, the phase shift value of the second phase shifter is configured to be any value, and the radio frequency power output by each of the two output channels of the second bridge is zero. That is, in case the phase shift value of the first phase shifter is configured to-90 °, the radio frequency power input to the power control network is output only at the second output channel (OUT 3) of the first bridge, i.e. the power control network outputs radio frequency power not zero only through OUT 3.
For example, in the case that the phase shift value of the first phase shifter is configured to +90°, and the phase shift value of the second phase shifter is configured to-90 °, the eighth radio frequency power output by the second output channel (OUT 3) of the first bridge is zero, and the seventh radio frequency power output by the first output channel of the first bridge is equal to the sum of the fifth radio frequency power and the sixth radio frequency power; the seventh radio frequency power output by the first bridge is input to the input end of the second power divider; the second power divider outputs ninth radio frequency power at the first output end and tenth radio frequency power at the second output end based on the seventh radio frequency power; since the phase shift value of the second phase shifter is configured to be-90 °, the ninth radio frequency power input by the second bridge and the tenth radio frequency power are completely cancelled by the power due to the opposite phase in the second output channel (OUT 2) of the second bridge, and the power is superimposed due to the same phase in the first output channel (OUT 1) of the second bridge, so that in an ideal case, the twelfth radio frequency power output by the second output channel (OUT 2) of the second bridge is zero, and the eleventh radio frequency power output by the first output channel (OUT 1) of the second bridge is equal to the sum of the ninth radio frequency power and the tenth radio frequency power. That is, the radio frequency power input to the power control network is output only at the first output channel (OUT 1) of the second bridge, i.e., the power control network outputs radio frequency power that is not zero only through OUT 1.
In an embodiment, the power control network outputs the radio frequency power of non-zero through at least two output channels OUT1, OUT2 and OU3 in case the phase shift values of the first phase shifter and the second phase shifter are each configured to be not equal to an odd multiple of 90 °.
For example, in the case where the phase shift value of the first phase shifter is configured to (+90+m) °, and M is not 0, the eighth radio frequency power output by the second output channel (OUT 3) of the first bridge is not zero and the seventh radio frequency power output by the first output channel of the first bridge is also not zero since the second output channel of the first bridge is not completely canceled due to the phase difference being not equal to 180 degrees. In the case where the phase shift value of the first phase shifter is configured to (-90+m) °, and M is not 0, the first output channel of the first bridge is not completely canceled due to the phase difference being not equal to 180 degrees, and therefore, the eighth radio frequency power output by the first output channel of the first bridge is not zero, and the seventh radio frequency power output by the second output channel (OUT 3) of the first bridge is also not zero.
As described above, in the case where the phase shift value of the second phase shifter is configured to +90°, the eleventh radio frequency power output from the first output channel (OUT 1) of the second bridge is zero; the twelfth radio frequency power output by the second output channel (OUT 2) of the second bridge is zero in case the phase shift value of the second phase shifter is configured to-90 deg.. Therefore, in the case where the phase shift value of the first phase shifter is configured to (+90+m) ° or (-90+m) °, and M is not 0, the radio frequency power input to the power control network simultaneously outputs the radio frequency power other than zero through at least two output channels.
Wherein, in the case that the phase shift value of the first phase shifter is configured to (+90+m) ° or (-90+m) ° and the phase shift value of the second phase shifter is configured to +90°, the radio frequency power input to the power control network is output at the second output channel (OUT 3) of the first bridge and the second output channel (OUT 2) of the second bridge, that is, the power control network outputs the radio frequency power which is not zero through OUT2 and OU 3.
In the case where the phase shift value of the first phase shifter is configured to (+90+M) ° or (-90+M) ° and the phase shift value of the second phase shifter is configured to-90 °, the radio frequency power input to the power control network is output at the second output channel (OUT 3) of the first bridge and the first output channel (OUT 1) of the second bridge, that is, the power control network outputs the radio frequency power that is not zero through OUT1 and OU3.
In the case where the phase shift value of the first phase shifter is configured to (+90+m) ° or (-90+m) °, and the phase shift value of the second phase shifter is configured to (+90+m) ° or (-90+m) °, the radio frequency power input to the power control network is output at the second output channel (OUT 3) of the first bridge, the first output channel (OUT 1) of the second bridge, and the second output channel (OUT 2) of the second bridge, that is, the power control network outputs the radio frequency power that is not zero through OUT1, OUT2, and OU 3.

In the scheme, by configuring the phase shift value for each phase shifter in the power control network, the two paths of output channels of the bridge connected with the corresponding phase shifter can be controlled to output radio frequency power simultaneously, the magnitude of the radio frequency power output by the corresponding two paths of output channels can be controlled, and the flexibility of radio frequency power control is improved.
