[0040] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0041] At present, the RF channel of a network supporting non-independent networking (E-UTRAN New Radio Dual Connectivity, ENDC) or uplink carrier aggregation (UpLink Carrier Aggregation) usually only includes an RF power amplifier and a transmit filter. The RF signal output from the RF power amplifier is filtered by the transmit filter and then output through the antenna. At this time, since the input tolerance power of the transmit filter is limited, the power of the RF signal output from the RF power amplifier needs to be lower than the input tolerance power of the transmit filter, thereby limiting the output power of the antenna.

[0042] Based on the above problems, an embodiment of the present application provides a radio frequency circuit. Figure 1 A schematic diagram of the structure of a radio frequency circuit provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the radio frequency circuit may include:

[0043] RF signal output terminal 10;

[0044] The signal distributor 11 comprises a first input terminal 110 and a plurality of first output terminals 111, wherein the first input terminal 110 is connected to the RF signal output terminal 10; the signal distributor 11 is used to distribute the output power of the RF signal output terminal 10 received through the first input terminal 110 to the plurality of first output terminals 111 for output;

[0045] A plurality of RF branches 12, each of the plurality of RF branches 12 having a first end 120 and a second end 121, each of the RF branches 12 including a target function module 123, the first end 120 of each RF branch 12 being connected to a plurality of first output ends 111; the target function module 123 having a target tolerance power value, the target tolerance power value of each target function module 123 in the plurality of RF branches 12 being the same or different;

[0046] An antenna unit 13, the antenna unit 13 is connected to the second end 121 of each radio frequency branch 12;

[0047] The output power of the RF signal output terminal 10 is greater than the target withstand power value of any target functional module 123 in the plurality of RF branches 12 .

[0048] It should be noted that, in the embodiment of the present application, the RF signal output terminal 10 may be a port in the RF circuit connected to a RF signal output module, and is used to output the RF signal of the RF signal output module through the RF signal output terminal 10 .

[0049] It should be noted that, in the embodiment of the present application, the signal distributor may be a device capable of distributing the radio frequency signal output by the radio frequency signal output terminal 10, and may be an antenna switching switch, etc.

[0050] It should be noted that, in the embodiment of the present application, the antenna unit 13 can be a radiator, which can convert the radio frequency signal into electromagnetic waves and radiate them in a specific direction in space; and the antenna unit 13 can be a communication antenna, a broadcasting antenna, a television antenna or a radar antenna, etc., and the number of antenna units 13 can be one or more.

[0051] It should be noted that, in the embodiment of the present application, the target functional module 123 can be used to process the radio frequency signal output by the signal distributor 11, and the target functional module 123 can be a filter or a low noise amplifier or other device.

[0052] It should be noted that in the embodiment of the present application, the RF signal output terminal 10 can output an electrical signal of a certain power and transmit it to the signal distributor 11 through the first input terminal 110. The signal distributor 11 can distribute the power of the received output electrical signal to multiple first output terminals 111 for output. The multiple first output terminals 111 can transmit part of the power of the electrical signal allocated to their own output through the first terminal 120 to the target functional module 123 in the RF branch 12. After the target functional module 123 processes part of the power of the electrical signal, the processed part of the power of the electrical signal is transmitted to the antenna unit 13 through the second terminal 121, and the processed electrical signal is transmitted via the antenna unit 13.

[0053] It should be noted that in the embodiment of the present application, the target functional module 123 on each RF branch 12 can have its own target tolerance power value. Since the output power of the RF signal output terminal 10 is greater than the target tolerance power value of each target functional module 123, the power of the output electrical signal of the RF signal output terminal 10 can be distributed to multiple first output terminals 111 through the signal distributor 11, and then the target functional module 123 can withstand part of the power of the distributed electrical signal.

[0054] It should be noted that in the embodiment of the present application, when the signal distributor 11 distributes the power of the output electrical signal, it can distribute the power of the output electrical signal evenly to each RF branch 12 according to the number of multiple RF branches 12, or it can distribute the power of the output electrical signal according to different target tolerance power values ​​of different target functional modules 123 on different RF branches 12; the distribution method can be determined according to actual conditions, and the embodiment of the present application is not limited here.

[0055] It should be noted that in the embodiments of the present application, reference is made to Figure 1 Since the plurality of first output terminals 111 can be connected to the plurality of first terminals 120 in a one-to-one correspondence, the number of the first output terminals 111 can be the same as the number of the RF branches 12 .

[0056] In the embodiment of the present application, the output power allocated to any one of the multiple RF branches 12 may be less than or equal to the target tolerance power value corresponding to the target functional module 123 on the RF branch 12 .

[0057] It should be noted that in the embodiment of the present application, the signal distributor 11 can distribute the power of the output electrical signal according to the target tolerance power value corresponding to the target functional module 123 on the RF branch 12. For example, the target tolerance power value corresponding to the target functional module 123 on the RF branch 12 is M. The signal distributor 11 can distribute the part of the power A in the output electrical signal that is equal to M to the RF branch 12, or, it can distribute the part of the power B in the output electrical signal that is less than M to the RF branch 12.

[0058] In the related art, since the output power of the RF signal output terminal 10 needs to be processed by the target functional module 123 before being emitted through the antenna unit 13, but the output power of the RF signal output terminal 10 is greater than the target tolerance power value of the target functional module 123, the target functional module 123 is at risk of being damaged.

[0059] Based on this, the present application can distribute the power of the output electrical signal of the RF signal output terminal 10 to multiple RF branches 12 through the signal distributor 11 and process it through the target function module 123. At this time, the output power allocated to each RF branch 12 can be less than or equal to the target tolerance power value corresponding to the target function module 123 on the RF branch 12.

[0060] It can be understood that the present application can avoid the problem of limiting the output power of the RF signal output terminal 10 due to the low target tolerance power value of the target functional module 123 itself by setting a signal distributor 11 between the RF branch 12 and the RF signal output terminal 10, thereby increasing the transmission power upper limit of the antenna unit 13.

[0061] In an optional embodiment of the present application, Figure 2 As shown, the radio frequency branch may also include:

[0062] The signal combiner 14 includes a plurality of second output terminals 141 and a plurality of second input terminals 142; the plurality of second input terminals 142 are correspondingly connected to the second terminals 121 of the plurality of RF branches 12, and the plurality of second output terminals 141 are connected to the antenna unit 13; the signal combiner 14 is used to distribute the output power received through the plurality of second input terminals 142 to the plurality of second output terminals 141 for output;

[0063] The target output power of a target second output end 141 among the plurality of second output ends 141 is greater than the target withstand power value of any target functional module 123 among the plurality of RF branches 12 .

[0064] It should be noted that in an embodiment of the present application, the signal combiner 14 can be located between multiple RF branches 12 and the antenna unit 13, and the multiple RF branches 12 can transmit part of the power of the processed electrical signals through multiple second ends 121 and the corresponding transmissions connected to the multiple second ends 121 to the signal combiner 14, and the signal combiner 14 can distribute part of the power of the received multiple processed electrical signals to the multiple second output ends 141 for output.

[0065] It should be noted that in the embodiment of the present application, if there is only one antenna unit 13, the signal combiner 14 will combine part of the power of the multiple processed electrical signals received and send it to the antenna unit 13 through multiple second output terminals 141 for radiation; if there are multiple antenna units 13, the signal combiner 14 will combine part of the power of the multiple processed electrical signals received and send the combined power to one of the multiple antenna units 13 for radiation through multiple second output terminals 141, or send the combined power to a group of antenna units 13 in the multiple antenna units 13 for radiation, that is, the antenna unit 13 with a better RF environment can be selected to radiate the combined power according to the different RF environments in which the multiple antenna units 13 are located to obtain a better radiation effect; the number of antenna units 13 and the way of redistributing the signal combiner 14 can be determined according to actual conditions, and the embodiment of the present application is not limited here.

[0066] It can be understood that since the target tolerance power value of a single target functional module 123 itself is low, it will limit the output power of the RF signal output terminal 10. In this application, the power of the output electrical signal is first distributed to multiple target functional modules 123 through the signal distributor 11, and then part of the power of the multiple processed electrical signals is combined through the signal combiner 14, and output to the antenna unit 13 through the target second output terminal 141, so that the antenna unit 13 can radiate the combined power, thereby not being limited by the target tolerance power value of the target functional module 123 itself, and can increase the maximum transmission power of the antenna unit 13.

[0067] An embodiment of the present application provides a radio frequency circuit, which includes: a radio frequency signal output terminal; a signal distributor, including a first input terminal and multiple first output terminals, the first input terminal being connected to the radio frequency signal output terminal; the signal distributor, which is used to distribute the output power of the radio frequency signal output terminal received through the first input terminal to multiple first output terminals for output; multiple radio frequency branches, each of the multiple radio frequency branches having a first terminal and a second terminal, each radio frequency branch including a target functional module, the first terminal of each radio frequency branch being connected to the multiple first output terminals; the target functional module having a target tolerance power value, the target tolerance power value of each target functional module in the multiple radio frequency branches being the same or different; an antenna unit, the antenna unit being connected to the second terminal of each radio frequency branch; wherein the output power of the radio frequency signal output terminal is greater than the target tolerance power value of any target functional module in the multiple radio frequency branches; by adopting the above implementation scheme, the present application can avoid the problem of limiting the output power of the radio frequency signal output terminal due to the low target tolerance power value of the target functional module itself by setting a signal distributor between the radio frequency branch and the radio frequency signal output terminal, thereby increasing the upper limit of the transmission power of the antenna unit.

[0068] Based on the above embodiment, in another embodiment of the present application, a radio frequency device is provided. Figure 3 A schematic diagram of the structure of a radio frequency device provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the radio frequency device 3 includes:

[0069] Radio frequency signal output module 30;

[0070] The signal distribution module 31 includes a first input terminal and a plurality of first output terminals, wherein the first input terminal is connected to the RF signal output module 30; the signal distribution module 31 is used to distribute the output power of the RF signal output module 30 received through the first input terminal to the plurality of first output terminals for output;

[0071] A plurality of RF processing modules 32, each of the plurality of RF processing modules 32 having a first end and a second end, each of the RF processing modules 32 including a target function module, the first end of each of the RF processing modules being connected to the plurality of first output ends; the target function module having a target tolerance power value, the target tolerance power value of each of the plurality of RF processing modules being the same or different;

[0072] An antenna module 33, wherein the antenna module 33 is connected to the second end of each RF processing module 32;

[0073] The output power of the RF signal output module 30 is greater than the target tolerance power value of any target functional module in the plurality of RF processing modules 32 .

[0074] It should be noted that in the embodiment of the present application, the RF signal output module 30 can output an electrical signal to the signal distribution module 31 through the first input terminal, and the signal distribution module 31 distributes the power of the received output electrical signal, and distributes part of the power of multiple electrical signals to multiple first output terminals for transmission to multiple RF processing modules 32. After receiving part of the power of multiple electrical signals, the multiple RF processing modules 32 can process part of the power through the target function module set on the RF processing module 32, and transmit the multiple processed partial powers to the antenna module 33 through the second terminal for transmission.

[0075] In an embodiment of the present application, the target functional module is a filter, and the filtering frequency band of each target functional module is different; or, the target functional module is a duplexer / multiplexer.

[0076] In the embodiment of the present application, each filter can be used to filter the output power of the received radio frequency signal output module based on the corresponding filtering frequency band to obtain the filtered output power.

[0077] It should be noted that in the embodiment of the present application, if the target functional module is a filter, since the target functional module, i.e., the filter, is set on each RF processing module in the RF processing module 32, after the multiple RF processing modules 32 receive the multiple partial electrical signals output by the signal distribution module through the multiple first output terminals, the filter on each RF processing module 32 can filter the partial electrical signals received on the RF processing module 32 based on its own filtering frequency band, that is, each RF processing module 32 will correspond to a filtered partial electrical signal, and multiple filtered partial electrical signals corresponding to the multiple RF processing modules 32 will be obtained.

[0078] In an optional embodiment of the present application, the radio frequency device 3 further includes a signal merging module, and the antenna module 33 includes a plurality of sub-antenna modules, wherein:

[0079] The signal merging module includes a plurality of second output terminals and a plurality of second input terminals; the plurality of second input terminals are correspondingly connected to the second terminals of the plurality of RF processing modules 32, and the plurality of second output terminals are correspondingly connected to the plurality of sub-antenna modules; the signal merging module is used to distribute the output power received through the plurality of second input terminals to the plurality of second output terminals for output;

[0080] At least two of the multiple sub-antenna modules are located at different positions, and the signal combining module is used to determine a distribution method for output powers received by the multiple second input ends according to the radio frequency environment of the sub-antenna modules.

[0081] It should be noted that in the embodiment of the present application, the signal merging module can be located between multiple RF processing modules 32 and the antenna module 33. After the multiple RF processing modules 32 transmit the multiple processed partial powers to the signal merging module, the signal merging module can merge the received multiple processed partial powers and redistribute them to multiple second output terminals for output.

[0082] It should be noted that in an embodiment of the present application, the antenna positions of multiple sub-antenna modules may be different, and thus, the RF environment of each sub-antenna module may be different. Therefore, when the signal merging module redistributes the processed power, it can distribute the processed power according to the antenna positions of the multiple sub-antenna modules and the RF environment in which the multiple sub-antenna modules are located, and try to transmit the processed output power through the optimal sub-antenna module.

[0083] In an optional embodiment of the present application, the transmission distances between at least two of the multiple sub-antenna modules and the signal merging module are different; wherein, when the radio frequency environments of the antenna positions of the multiple sub-antenna modules are the same, the signal merging module is used to merge the output powers received by the multiple second input ends and emit them through the first sub-antenna module; the first sub-antenna module is the sub-antenna module among the multiple sub-antenna modules having the shortest electrical signal transmission distance from the signal merging module.

[0084] It should be noted that in the embodiment of the present application, the antenna position of each sub-antenna module may be different. Therefore, the transmission distance between each sub-antenna module and the signal combining module may be different, and the processed power needs to be further allocated according to the RF environment in which each sub-antenna module is located.

[0085] Specifically, when the RF environments of the antenna positions of multiple sub-antenna modules are the same, since the longer the transmission distance, the greater the power loss, the processed power can be emitted through the first sub-antenna module among the multiple sub-antenna modules that is shortest from the signal merging module; when the RF environments of the antenna positions of multiple sub-antenna modules are different, it is necessary to further measure the differences between the RF environments of each sub-antenna module and the power loss caused by the transmission distance between each sub-antenna module and the signal merging module, and then determine the second sub-antenna module with the best signal transmission environment from the multiple sub-antenna modules, and then emit the processed power through the second sub-antenna module; the method of selecting the sub-antenna module that transmits the processed power from the multiple sub-antenna modules can be determined according to actual conditions, and the embodiments of the present application are not limited here.

[0086] In an optional embodiment of the present application, the RF signal output module 30 includes multiple RF signal output terminals, and the number of first input terminals is multiple; the multiple RF signal output terminals are correspondingly connected to the multiple first input terminals; wherein the transmission distances between the multiple first output terminals and the multiple RF processing modules are different; the signal distribution module is used to determine the distribution method of the output power of the received multiple RF signal output terminals according to the line power loss over the transmission distance between the multiple first output terminals and the multiple RF processing modules, and the target tolerance power value of each target functional module in the multiple RF processing modules.

[0087] It should be noted that in the embodiment of the present application, since the transmission distance between the signal distribution module 31 and each RF processing module 32 is different, when the signal distribution module 31 distributes the power of the received electrical signal to different RF processing modules 32, it can distribute the power of the received electrical signal according to the line power loss on each transmission line and the target tolerance power value of the target functional module in each RF processing module 32; the distribution method can be determined according to actual conditions, and the embodiment of the present application is not limited here.

[0088] Specifically, when the signal distribution module 31 distributes the power of the electrical signal to the RF processing module 32, it can distribute the maximum power to the RF processing module 32 as much as possible according to the target tolerance power value of the target functional module in the RF processing module 32, that is, the power value of the partial power distributed to the RF processing module 32 is equal to the target tolerance power value of the target functional module. At this time, since there is a transmission distance between the RF processing module 32 and the signal distribution module 31, and thus there is a line power loss, assuming that the target tolerance power value of the RF processing module 32 is N, and the line power loss is O, the signal distribution module 31 can distribute a partial power of N+O to the RF processing module 32. When this partial power is transmitted from the signal distribution module 31 to the RF processing module 32, the remaining power value is just equal to the target tolerance power value of the RF processing module 32, thereby being able to increase the maximum transmission power on the transmission branch; in addition, when the signal distribution module 31 distributes power to the RF processing module 32, it can also distribute a partial power less than N+O.

[0089] The embodiment of the present application provides a radio frequency device, which includes: a radio frequency signal output module; a signal distribution module, including a first input end and a plurality of first output ends, the first input end being connected to the radio frequency signal output module; the signal distribution module is used to distribute the output power of the radio frequency signal output module received through the first input end to the plurality of first output ends for output; a plurality of radio frequency processing modules, each of the plurality of radio frequency processing modules having a first end and a second end, each of the radio frequency processing modules including a target function module, the first end of each of the radio frequency processing modules being connected to the plurality of first output ends; the target function module The group has a target tolerance power value, and the target tolerance power value of each target functional module in the multiple RF processing modules is the same or different; an antenna module, the antenna module is connected to the second end of each RF processing module; wherein the output power of the RF signal output module is greater than the target tolerance power value of any one of the target functional modules in the multiple RF processing modules; adopting the above-mentioned implementation scheme, the present application can avoid the problem of limiting the output power of the RF signal output end due to the low target tolerance power value of the target functional module itself by setting a signal distributor between the RF branch and the RF signal output end, thereby increasing the upper limit of the transmission power of the antenna module.

[0090] Based on the above embodiment, in another embodiment of the present application, Figure 4 As shown, Figure 4 A schematic diagram of the composition structure of another radio frequency device provided in an embodiment of the present application, the radio frequency device may include:

[0091] A first RF power amplifier 40 and a second power amplifier 41;

[0092] Antenna switching switch 42 and antenna switching switch 43;

[0093] Transmit filter 44 and transmit filter 45;

[0094] A first antenna 46 and a second antenna 47 .

[0095] It should be noted that in the embodiments of the present application, the first RF power amplifier 40 and the second power amplifier 41 correspond to the RF signal output terminal 10 in the first embodiment, or the RF signal output module 30 in the second embodiment; the antenna switching switch 42 corresponds to the signal distributor 11 in the first embodiment, or the signal distribution module 31 in the second embodiment, and the antenna switching switch 43 corresponds to the signal combiner 14 in the first embodiment, or the signal combining module 34 in the second embodiment; the transmitting filter 44 and the transmitting filter 45 correspond to the RF branch 12 in the first embodiment, or the RF processing module 32 in the second embodiment; the first antenna 46 and the second antenna 47 correspond to the antenna unit 13 in the first embodiment, or the antenna module 33 in the second embodiment.

[0096] Specifically, the first RF power amplifier 40 / the second power amplifier 41 outputs RF power to the antenna switching switch 42. Since the RF power output by the first RF power amplifier 40 / the second power amplifier 41 is greater than the maximum tolerable power value that the transmit filter 44 / the transmit filter 45 can withstand, the antenna switching switch 42 divides the RF power output by the first RF power amplifier 40 / the second power amplifier 41, and a part of the RF power enters the transmit filter 44, and the other part of the RF power enters the transmit filter 45. After the RF power is filtered by the transmit filter 44 and the transmit filter 45, the transmit filter 44 and the transmit filter 45 transmit the processed RF power to the antenna switching switch 43, and then the antenna switching switch 43 combines the received RF power output by the transmit filter 44 and the transmit filter 45, and transmits it through the first antenna 46 / the second antenna 47.

[0097] It can be understood that, through the technical solution of the present application, the RF power transmitted to the transmitting filter can be reduced, thereby significantly improving the output power of the entire RF channel while ensuring that the transmitting filter is not burned.
