Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a radio frequency system and communication equipment. Background Art

[0002] With the development of communication technology, communication equipment is being used more and more. Communication equipment uses a low-noise amplifier to perform low-noise amplification processing on the received radio frequency signal to achieve reception and processing of the radio frequency signal. Since the low-noise amplifier is an active device, it needs to be powered to work properly.

[0003] However, during the communication process, signal reception actually occupies a large proportion of the time, and related technologies often use a constant voltage to power the low-noise amplifier, resulting in high power consumption of the communication equipment. Summary of the invention

[0004] Based on this, it is necessary to provide a radio frequency system and communication equipment that can reduce power consumption.

[0005] In a first aspect, an embodiment of the present application provides a radio frequency system, including:

[0006] At least two transceiver circuits, each of which comprises a power amplifier module and a low noise amplifier module;

[0007] At least two power supply modules, including at least one target power supply module, the target power supply module is respectively connected to the target power amplification module and the target low-noise amplification module, and the target power supply module is used to provide power supply voltage to the target power amplification module and the target low-noise amplification module in a time-sharing manner; wherein the target power amplification module and the target low-noise amplification module correspond to different transceiver circuits;

[0008] A control module is connected to each of the power modules and is used to control the target power module to provide a supply voltage according to the gain information of the target low-noise amplifier module when the RF system operates in a single connection mode, so as to power the target low-noise amplifier module, and to control the supply voltage of the remaining power modules to support any one of the transceiver circuits to simultaneously transmit and receive RF signals.

[0009] In a second aspect, an embodiment of the present application provides a communication device, wherein the communication device includes the radio frequency system as described above.

[0010] The above-mentioned radio frequency system and communication equipment control the supply voltage of the target power supply module according to the gain information of the target low-noise amplification module through the control module. Therefore, in the process of supporting the reception of radio frequency signals through the transceiver circuit where the target low-noise amplification module is located, the supply voltage provided by the target power supply module to the target low-noise amplification module can be dynamically adjusted according to the gain information of the target low-noise amplification module. Compared with the use of a constant voltage to power the target low-noise amplification module in the related art, that is, regardless of whether the gain of the target low-noise amplification module is large or small, a fixed voltage is used to power the target low-noise amplification module. This embodiment can reduce the power consumption of the radio frequency system. In addition, since the target power supply module can provide the supply voltage to the target power amplification module and the target low-noise amplification module in a time-sharing manner, the target power amplification module and the target low-noise amplification module reuse the target power supply module, and there is no need to set up a power supply module separately for the target power amplification module and the target low-noise amplification module, thereby reducing the cost.

[0031] The radio frequency system involved in the embodiment of the present application can be applied to a communication device with a communication function, and the communication device can be a handheld device, a vehicle-mounted device, a wearable device, a computing device, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE) (e.g., a mobile phone), a mobile station (MS), etc. For the convenience of description, the above-mentioned devices are collectively referred to as communication devices.

[0032] In one embodiment, Figure 1 As shown, a radio frequency system is provided, which includes at least two transceiver circuits 10 , at least two power modules 20 and a control module 30 .

[0033] Each transceiver circuit 10 includes a power amplifier module and a low noise amplifier module. The power amplifier module is used to support power amplification processing of the first RF signal. Exemplarily, the power amplifier module includes a power amplifier (Poweramplifier, PA). The low noise amplifier module is used to support low noise amplification processing of the second RF signal. Among them, the frequency bands of the first RF signal and the second RF signal can be the same or different, and can be set according to actual application requirements, and are not limited too much here. Exemplarily, the low noise amplifier module includes a low noise amplifier (Low noiseamplifier, LNA). The number of transceiver circuits 10 can be 2, 3, 4 or other values ​​greater than 2, and can be set according to factors such as communication requirements, and are not limited here.

[0034] Exemplarily, the power module 20 includes a power supply and a DC-DC converter (DC-DC converter, DCDC). The number of power modules 20 can be 2, 3, 4 or other values ​​greater than 2, and can be specifically set according to factors such as the power supply demand of the RF system and the specific structure of the RF system, which is not limited here. Among them, at least two power modules 20 include at least one target power module 201. The number of target power modules 201 is less than or equal to the number of power modules 20. Among them, the target power module 201 is connected to the target power amplifier module 101 and the target low-noise amplifier module 102 respectively. The target power module 201 is used to provide power supply voltage to the target power amplifier module 101 and the target low-noise amplifier module 102 in time sharing. Among them, the target power amplifier module 101 is a power amplifier module in any transceiver circuit 10 in the RF system, and the target low-noise amplifier module 102 is a low-noise amplifier module in any transceiver circuit 10 in the RF system, and the target power amplifier module 101 and the target low-noise amplifier module 102 correspond to different transceiver circuits 10.

[0035] When the number of target power modules 201 is less than the transceiver circuit 10, the remaining low noise amplifier modules and the remaining power amplifier modules that are not connected to the target power modules 201 can be connected to the remaining power modules 20 respectively to be powered by the remaining power modules 20. For example, Figure 1 The radio frequency system shown includes two transceiver circuits 10 and three power modules 20, and the three power modules 20 are respectively taken as examples of a target power module 201, a first remaining power module 202 and a second remaining power module 203, wherein the target power module 201 is connected to the target low-noise amplification module 102 and the target power amplification module 101, the first remaining power module 202 is connected to the low-noise amplification module 103 in the transceiver circuit 10 where the target power amplification module 101 is located, and the second remaining power module 203 is connected to the power amplification module 104 in the transceiver circuit 10 where the target low-noise amplification module 102 is located, wherein the target power module 201 can respectively supply power to the target low-noise amplification module 102 and the target power amplification module 101, the first remaining power module 202 can supply power to the low-noise amplification module 103, and the second remaining power module 203 can supply power to the power amplification module 104.

[0036] It should be noted that the above is only an exemplary description and should not be understood as a specific limitation of the present application on the transceiver circuit 10, the power module 20, and the connection relationship between the transceiver circuit 10 and the power module 20 of the RF system. For example, the same remaining power module 20 can be respectively connected to the low-noise amplifier module and the power amplifier module of the same transceiver circuit 10. In actual applications, it can be set according to specific scenarios and application requirements, and no excessive limitations are made here.

[0037] The control module 30 is connected to each power module 20. The control module 30 is used to control the target power module 201 to provide a power supply voltage according to the gain information of the target low-noise amplifier module 102 when the RF system is operating in a single connection mode, so as to power the target low-noise amplifier module 102, and to control the power supply voltage of the remaining power modules 20 to support any transceiver circuit 10 to simultaneously receive and transmit RF signals. The single connection mode refers to a working mode in which any transceiver circuit 10 in the RF system simultaneously receives and transmits RF signals, or it can be understood as a single transceiver circuit 10 in the RF system operating in a frequency division duplexing mode.

[0038] The gain information is used to indicate the gain size of the target low-noise amplification module 102. When the transceiver circuit 10 in which the target low-noise amplification module 102 is located operates in FDD mode, the power supply voltage provided by the target power supply module 201 to the target low-noise amplification module 102 changes dynamically with the gain information of the target low-noise amplification module 102. Exemplarily, the power supply voltage provided by the target power supply module 201 to the target low-noise amplification module 102 is positively correlated with the gain information of the target low-noise amplification module 102; that is, the greater the gain of the target low-noise amplification module 102, the greater the power supply voltage provided by the target power supply module 201 to the target low-noise amplification module 102; the smaller the gain of the target low-noise amplification module 102, the smaller the power supply voltage provided by the target power supply module 201 to the target low-noise amplification module 102. In an embodiment of the present application, this is referred to as a receiving APT (Average Power Tracking) mode.

[0039] In this embodiment, the power supply voltage of the target power supply module 201 is controlled according to the gain information of the target low-noise amplification module 102. Therefore, in the process of supporting the reception of radio frequency signals through the transceiver circuit 10 where the target low-noise amplification module 102 is located, the power supply voltage provided by the target power supply module 201 to the target low-noise amplification module 102 can be dynamically adjusted according to the gain information of the target low-noise amplification module 102. Compared with the use of a constant voltage to power the target low-noise amplification module 102 in the related art, that is, regardless of whether the gain of the target low-noise amplification module 102 is large or small, a fixed voltage is used to power the target low-noise amplification module 102. This embodiment can reduce the power consumption of the radio frequency system. In addition, since the target power supply module 201 can provide the power supply voltage to the target power amplification module 101 and the target low-noise amplification module 102 in a time-sharing manner, the target power amplification module 101 and the target low-noise amplification module 102 reuse the target power supply module 201, and there is no need to separately set a power supply module 20 for powering the target power amplification module 101 and the target low-noise amplification module 102, thereby reducing the cost.

[0040] In one embodiment, please refer to Figure 1 The control module 30 can also be used to control the target power supply module 201 to provide a supply voltage according to the output power of the target power amplifier module 101, so as to power the target power amplifier module 101; in this case, the supply voltage provided by the target power supply module 201 to the target power amplifier module 101 changes dynamically with the output power of the target power amplifier module 101.

[0041] Exemplarily, the power supply voltage provided by the target power supply module 201 to the power amplifier module is positively correlated with the output power of the target power amplifier module 101; that is, the greater the output power of the target power amplifier module 101, the greater the power supply voltage provided by the target power supply module 201 to the target output power; the smaller the output power of the target output power, the smaller the power supply voltage provided by the target power supply module 201 to the target output power. That is, the RF system operates in APT mode. In order to facilitate the distinction from the aforementioned receiving APT mode, in this embodiment, this is referred to as the transmitting APT mode. Based on this, it can be seen that the present application not only supports the transmitting APT mode, but also supports the receiving APT mode, which helps to further reduce power consumption.

[0042] It can be understood that since the target power amplifier module 101 and the target low-noise amplifier module 102 correspond to different transceiver circuits 10, when the RF system operates in a single connection mode, for example, when the transceiver circuit 10 where the target low-noise amplifier module 102 is located supports simultaneous transceiver of RF signals, the control module 30 can control the target power supply module 201 to provide a power supply voltage to power the target low-noise amplifier module 102 according to the gain information of the target low-noise module, and control the remaining power supply modules 20 connected to the power amplifier module to provide a power supply voltage to power the power amplifier module according to the output power of the power amplifier module in the transceiver circuit 10 where the target low-noise module is located, thereby realizing that a single transceiver circuit 10 of the RF system supports the transmit APT and receive APT modes under FDD, and further reduces power consumption compared to using a constant voltage to power the low-noise amplifier and / or power amplifier. For another example, when the transceiver circuit 10 where the target power amplifier module 101 is located supports simultaneous transmission and reception of radio frequency signals, the control module 30 can control the target power supply module 201 to provide a power supply voltage to power the power amplifier module according to the output power of the target power amplifier module 101, and control the remaining power supply module 20 connected to the low-noise amplifier module to provide a power supply voltage to power the low-noise amplifier module according to the gain information of the low-noise module in the transceiver circuit 10 where the target power amplifier module 101 is located, thereby enabling a single transceiver circuit 10 of the radio frequency system to support the transmit APT and receive APT modes under FDD, thereby reducing power consumption compared to using a constant voltage to power the low-noise amplifier and / or power amplifier.

[0043] In one embodiment, please refer to Figure 1, the gain information includes a gain level, and different gain levels correspond to different supply voltages of the target power module 201. Exemplarily, the gain level of the target low-noise amplification module 102 is positively correlated with the supply voltage provided by the target power module 201 to the target low-noise amplification module 102; that is, the greater the gain level of the target low-noise amplification module 102, the greater the supply voltage provided by the target power module 201 to the target low-noise amplification module 102; the smaller the gain level of the target low-noise amplification module 102, the smaller the supply voltage provided by the target power module 201 to the target low-noise amplification module 102.

[0044] Exemplarily, the gain level of the target low-noise amplification module 102 is positively correlated with the signal strength of the RF signal processed by the target low-noise amplification module 102 for low-noise amplification; that is, the greater the signal strength of the RF signal processed by the target low-noise amplification module 102 for low-noise amplification, the greater the gain level of the target low-noise amplification module 102; the smaller the signal strength of the RF signal processed by the target low-noise amplification module 102 for low-noise amplification, the smaller the gain level of the target low-noise amplification module 102.

[0045] For example, Table 1 provides a correspondence between the signal strength of a radio frequency signal subjected to low noise amplification processing by a target low noise amplification module 102, the gain level of the target low noise amplification module 102, and the power supply voltage provided by the target power supply module 201 to the target low noise amplification module 102.

[0046] Table 1

[0047] Signal Strength LNA gain levels Supply voltage Within -50dBm G0 0.7V -50dBm to -65dBm G1 1.0V -65dBm to -80dBm G2 1.2V -80dBm to -95dBm G3 1.4V -95dBm to -105dBm G4 1.6V -105dBm or above G5 1.8V

[0048] It should be noted that the above table is only for illustrative purposes. In actual applications, the mapping relationship between signal strength, gain level and supply voltage can also be designed in other ways, and no excessive limitations are made here.

[0049] In one embodiment, Figure 2 As shown, the control module 30 includes a radio frequency transceiver 31 and a processor 32. The radio frequency transceiver 31 is connected to each power amplifier module and each low noise amplifier module respectively. The radio frequency transceiver 31 is used to determine the gain level of the target low noise amplifier module 102. Exemplarily, the radio frequency transceiver 31 is used to determine the gain level of the target low noise amplifier module 102 according to the signal strength of the radio frequency signal after low noise amplification processing by the target low noise amplifier module 102. In application, the radio frequency transceiver 31 can be used to store a first mapping relationship between the signal strength of the radio frequency signal and the gain level. After receiving the radio frequency signal after low noise amplification processing by the target low noise amplifier module 102, the gain level of the target low noise amplifier module 102 can be determined according to the first mapping relationship.

[0050] The processor 32 is connected to the RF transceiver 31 and each power module 20 respectively. The processor 32 is used to control the target power module 201 to provide a power supply voltage according to the gain level to power the target low-noise amplifier module 102. Exemplarily, the processor 32 includes a microprocessor unit (MCU). In the application, the processor 32 can be used to store the second mapping relationship between the gain level of the target low-noise amplifier module 102 and the power supply voltage of the target power module 201. After receiving the gain level of the target low-noise amplifier module 102, the power supply voltage of the target power module 201 can be determined according to the second mapping relationship, and the corresponding control instruction can be output according to the power supply voltage to control the target power module 201 to output the power supply voltage through the control instruction, thereby powering the target low-noise amplifier module 102. Among them, the type of control instruction can be determined according to the interface type between the processor 32 and the target power module 201, for example, MIPI (Mobile Industry Processor Interface, mobile industry processor 32 interface) instruction, or other types of control instructions, which are not limited too much here.

[0051] In this embodiment, the gain level of the target low-noise amplifier module 102 is determined by the RF transceiver 31, and the supply voltage of the target power supply module 201 is determined according to the gain level by the processor 32, so that the target power supply module 201 is controlled to output different supply voltages according to different gain levels, thereby realizing APT mode power supply for the target low-noise amplifier module during the receiving process, thereby reducing power consumption.

[0052] In one embodiment, please refer to Figure 2, at least two transceiver circuits 10 include a first transceiver circuit 11 and a second transceiver circuit 12. The first transceiver circuit 11 includes a first power amplifier module 111 and a first low noise amplifier module 112. Exemplarily, the first transceiver circuit 11 includes a power amplifier module with a built-in low noise amplifier (PA Mid With LNA, L-PAMid). The second transceiver circuit 12 includes a second power amplifier module 121 and a second low noise amplifier module 122. Exemplarily, the second transceiver circuit 12 includes a power amplifier module with a built-in low noise amplifier (L-PAMid). The first transceiver circuit 11 and the second transceiver circuit 12 support different frequency bands of RF signals. For example, the first transceiver circuit 11 includes a middle and high frequency power amplifier module with a built-in low noise amplifier (Middle High Band PA Mid With LNA, MHB L-PAMid), and the second transceiver circuit 12 includes a low frequency power amplifier module with a built-in low noise amplifier (Low Band PA Mid With LNA, LB L-PA Mid). The at least two power modules 20 include a first target power module 21 and a second target power module 22 .

[0053] The first target power supply module 21 is respectively connected to the first power amplifier module 111 and the second low-noise amplifier module 122, and the first target power supply module 21 is used to provide the first power supply voltage to the first power amplifier module 111 and the second low-noise amplifier module 122 in a time-sharing manner. Exemplarily, the control module 30 is also respectively connected to the first power amplifier module 111, the second low-noise amplifier module 122, and the first target power supply module 21, and the control module 30 is also used to control the power supply voltage of the first target power supply module 21, and the working states of the first power amplifier module 111 and the second low-noise amplifier module 122, so that the first power amplifier module 111 and the second low-noise amplifier module 122 work in a time-sharing manner.

[0054] The second target power supply module 22 is respectively connected to the second power amplification module 121 and the first low-noise amplification module 112, and the second target power supply module 22 is used to provide the second power supply voltage to the second power amplification module 121 and the first low-noise amplification module 112 in a time-sharing manner. Exemplarily, the control module 30 is also respectively connected to the second power amplification module 121, the first low-noise amplification module 112, and the second target power supply module 22, and the control module 30 is also used to control the power supply voltage of the second target power supply module 22, and the working states of the second power amplification module 121 and the first low-noise amplification module 112, so that the second power amplification module 121 and the first low-noise amplification module 112 work in a time-sharing manner.

[0055] In this embodiment, the first target power supply module 21 is used to provide the first power amplifier module 111 and the second low-noise amplifier module 122 with a first power supply voltage in a time-sharing manner, and the second target power supply module 22 is used to provide the second power amplifier module 121 and the first low-noise amplifier module 112 with a second power supply voltage in a time-sharing manner, thereby realizing the multiplexing of the first target power supply module 21 by the first power amplifier module 111 and the second low-noise amplifier module 122, and also realizing the multiplexing of the second target power supply module 22 by the second power amplifier module 121 and the first low-noise amplifier module 112. There is no need to set four power supply modules 20 for the two transceiver circuits 10 to respectively power each low-noise amplifier module and each power amplifier module, thereby greatly reducing the cost.

[0056] In one embodiment, please refer to Figure 2 , the control module 30 is connected to the first target power module 21 and the second target power module 22 respectively. The control module 30 is also used to control the first target power module 21 to provide a first power supply voltage to power the first power amplifier module 111 when the RF system works in a single connection mode, and to control the second target power module 22 to provide a second power supply voltage to power the first low-noise amplifier module 112 according to the gain information of the first low-noise amplifier module 112, so as to support the first transceiver circuit 11 to simultaneously transmit and receive RF signals. Among them, the process of the control module 30 controlling the second target power module 22 to provide the second power supply voltage according to the gain information of the first low-noise amplifier module 112 is the same as the process of the control module 30 controlling the power supply voltage of the target power module 201 according to the gain information of the target low-noise amplifier module 102. For details, please refer to the above-mentioned related instructions, which will not be repeated here.

[0057] It can be understood that the first low-noise amplification module 112 is powered by the second target power supply module 22, and the first power amplification module 111 is powered by the first target power supply module 21. Therefore, when the first transceiver circuit 11 supports simultaneous transmission and reception of RF signals, that is, when the RF system supports the FDD mode through the first transceiver circuit 11, the control module 30 can dynamically adjust the supply voltage of the second target power supply module 22 according to the gain information of the first low-noise amplification module 112, thereby realizing the receiving APT mode under the FDD of a single transceiver circuit 10 and reducing power consumption.

[0058] Exemplarily, the control module 30 is also used to control the first target power module 21 to provide a first power supply voltage to power the first power amplifier module 111 according to the output power of the first power amplifier module 111, and control the second target power module 22 to provide a second power supply voltage to power the first low-noise amplifier module 112 according to the gain information of the first low-noise amplifier module 112, so as to support the first transceiver circuit 11 to simultaneously transmit and receive radio frequency signals. The process of the control module 30 controlling the first target power module 21 to provide the first power supply voltage according to the output power of the first power amplifier module 111 is the same as the process of the control module 30 controlling the power supply voltage of the target power module 201 according to the output power of the target power amplifier module 101. For details, please refer to the above-mentioned related description, which will not be repeated here.

[0059] It can be understood that the first low-noise amplification module 112 is powered by the second target power supply module 22, and the first power amplification module 111 is powered by the first target power supply module 21, that is, the power supply modules 20 that power the first low-noise amplification module 112 and the first power amplification module 111 are independent of each other. Therefore, when supporting simultaneous transmission and reception of RF signals through the first transceiver circuit 11, not only can the power supply voltage of the second target power supply module 22 be dynamically adjusted according to the gain information of the first low-noise amplification module 112, but the power supply voltage of the first target power supply module 21 can also be dynamically adjusted according to the output power of the first power amplification module 111, thereby enabling the RF system to support the transmit APT and receive APT modes under FDD through the first transceiver circuit 11, thereby further reducing system power consumption.

[0060] In one embodiment, please refer to Figure 2 The control module 30 is also used to control the second target power module 22 to provide a second power supply voltage to power the second power amplifier module 121 when the RF system is operating in a single connection mode, and to control the first target power module 21 to provide a first power supply voltage to power the second low-noise amplifier module 122 according to the gain information of the second low-noise amplifier module 122, so as to support the second transceiver circuit 12 to simultaneously transmit and receive RF signals. The process in which the control module 30 controls the first target power module 21 to provide the first power supply voltage according to the gain information of the second low-noise amplifier module 122 is the same as the process in which the control module 30 controls the power supply voltage of the target power module 201 according to the gain information of the target low-noise amplifier module 102. For details, please refer to the above-mentioned related descriptions, which will not be repeated here.

[0061] Exemplarily, the control module 30 is also used to control the second target power module 22 to provide a second power supply voltage to power the second power amplifier module 121 according to the output power of the second power amplifier module 121, and to control the first target power module 21 to provide a first power supply voltage to power the second low-noise amplifier module 122 according to the gain information of the second low-noise amplifier module 122, so as to support the second transceiver circuit 12 to simultaneously transmit and receive radio frequency signals. The process in which the control module 30 controls the second target power module 22 to provide the second power supply voltage according to the output power of the second power amplifier module 121 is the same as the process in which the control module 30 controls the power supply voltage of the target power module 201 according to the output power of the target power amplifier module 101. For details, please refer to the above-mentioned related description, which will not be repeated here.

[0062] It can be understood that the second low-noise amplifier module 122 is powered by the first target power module 21, and the second power amplifier module 121 is powered by the second target power module 22. Therefore, when the second transceiver circuit 12 supports simultaneous transceiver of radio frequency signals, that is, when the radio frequency system supports the FDD mode through the second transceiver circuit 12, the control module 30 can dynamically adjust the power supply voltage of the first target power module 21 according to the gain information of the second low-noise amplifier module 122, thereby realizing the receiving APT mode under a single transceiver circuit 10FDD and reducing power consumption. Furthermore, the control module 30 can also dynamically adjust the power supply voltage of the second target power module 22 according to the output power of the second power amplifier module 121, thereby realizing the transmitting APT mode under a single transceiver circuit 10FDD, thereby realizing the transmitting APT and receiving APT modes under a single transceiver circuit 10FDD, further reducing power consumption.

[0063] As for PA and LNA, since the working of the two devices is very different, PA generally requires a large voltage, while LNA requires a small voltage. Therefore, in this embodiment, the target low noise amplifier module 102 and the target power amplifier module 101 of the target power module 201 are reused to realize the transmitting APT and receiving APT modes under FDD. The target low noise amplifier module 102 and the target power amplifier module 101 need to switch between working in a certain time sequence.

The first power amplifier module 111 is turned on before the first target power module 21, and the second low-noise amplifier module 122 is completely turned off; 2. After the power amplifier module is turned on (black box buffer), the first target power module 21 starts to supply power to the first power amplifier module 111, and the first power supply voltage of the first target power module 21 is dynamically adjusted according to the output power of the first power amplifier module 111; 3. When the transmission cycle is about to end, the first target power module 21 starts to shut down and stop supplying power; 4. After the first target power module 21 stops supplying power, the first power amplifier module 111 starts to shut down (black box buffer).

When the receiving cycle is about to end, the second target power module 22 starts to shut down and stop supplying power; 4. After the second target power module 22 stops supplying power, the first low-noise amplifier module 112 starts to shut down (black box buffer).

[0066] The second transceiver circuit 12 (referred to as the second path) FDD transmission cycle: 1. The second power amplifier module 121 is turned on before the second target power supply module 22. At this time, the low noise amplifier module of the first receiving device is completely turned off; 2. After the second power amplifier module 121 is turned on (black box buffer), the second target power supply module 22 starts to supply power to the second power amplifier module 121. At this time, the second power supply voltage of the second target power supply module 22 is dynamically adjusted according to the output power of the second power amplifier module 121; 3. When the transmission cycle is about to end, the second target power supply module 22 starts to shut down and stop supplying power; 4. After the second target power supply module 22 stops supplying power, the second power amplifier module 121 starts to shut down (black box buffer).

[0067] The second FDD receiving cycle: 1. The second low-noise amplifier module 122 is turned on before the first target power module 21, and the first power amplifier module 111 is completely turned off; 2. After the second low-noise amplifier module 122 is turned on (black box buffer), the first target power module 21 starts to supply power to the second low-noise amplifier module 122. At this time, the first power supply voltage of the first target power module 21 is dynamically adjusted according to the gain level of the second low-noise amplifier module 122; 3. When the receiving cycle is about to end, the first target power module 21 starts to shut down and stop supplying power; 4. After the first target power module 21 stops supplying power, the first low-noise amplifier module 112 starts to shut down (black box buffer).

[0068] The radio frequency system provided in this embodiment can adjust different supply voltages according to different gain levels. Compared with the constant voltage method used in related technologies, this refined control can be more conducive to saving power consumption. Figure 4 As shown, from Figure 4 It can be seen that the black part is the power consumption that can be saved within a unit time. Specifically, the area difference caused by the constant voltage and time product in the related technology minus the existing dynamic voltage and time product is the power consumption benefit brought by this embodiment. In addition, the low-noise amplifier module and the power amplifier module of different transceiver circuits 10 reuse the same target power module 201, which reduces the cost. In addition, when the RF system operates in FDD mode, since it is necessary to support the simultaneous transmission and reception of RF signals, that is, it is necessary to power the power amplifier module and the low-noise amplifier module at the same time, in this regard, this embodiment uses the same target power module 201 to power the low-noise amplifier module and the power amplifier module of different transceiver circuits 10, that is, a cross-power supply method, such as Figure 2 In the embodiment, the first target power supply module 21 supplies power to the first power amplifier module 111 and the second low-noise amplifier module 122 respectively, and the second target power supply module 22 supplies power to the second power amplifier module 121 and the first low-noise amplifier module 112 respectively, thereby realizing the multiplexing of the target power supply module 201 by the low-noise amplifier module and the power amplifier module, reducing the cost, and realizing the transmitting APT and receiving APT under single-channel FDD, further reducing the power consumption.

[0069] In one embodiment, Figure 5As shown, the RF system also includes at least one receiving circuit. The number of receiving circuits can be 1, 2, 3 or other values ​​greater than 1, which can be set according to actual communication needs and is not limited here. The receiving circuit includes a low-noise amplifier module 40. Exemplarily, the low-noise amplifier module 40 can be connected to any transceiver circuit 10 so that the low-noise amplifier module 40 supports low-noise amplification processing of the RF signal received by the antenna of the transceiver circuit 10, realizes antenna multiplexing of the transceiver circuit 10, and helps to further reduce costs and achieve a narrow border. For example, Figure 5 In the RF system shown, the transceiver circuit 10 where the target low noise amplifier module 102 is located is connected to the low noise amplifier module 40. Exemplarily, the low noise amplifier module 40 includes a low noise amplifier for supporting low noise amplification processing of the RF signal.

[0070] The target power module 201 is also connected to at least one low-noise amplifier module 40. In application, the target power module 201 can be connected to some of the low-noise amplifier modules 40, or can be connected to all of the low-noise amplifier modules 40, which is not limited here. The target power module 201 is also used to simultaneously provide a power supply voltage to the target low-noise amplifier module 102 and at least one low-noise amplifier module 40, so that the target low-noise amplifier module 102 and at least one low-noise amplifier module 40 powered by the target power module 201 support simultaneous low-noise amplification processing of radio frequency signals, wherein the target low-noise amplifier module 102 and at least one low-noise amplifier module 40 connected to the target power module 201 support different frequency bands of radio frequency signals, thereby supporting simultaneous reception of radio frequency signals of multiple frequency bands.

[0071] In the case where the target power module 201 is connected to multiple low-noise amplifier modules 40, the target power module 201 can be used to simultaneously provide a power supply voltage for the target low-noise amplifier module 102 and partially connected low-noise amplifier modules 40, and the target power module 201 can also simultaneously provide a power supply voltage for the target low-noise amplifier module 102 and all connected low-noise amplifier modules 40, which can be specifically set according to actual receiving requirements and are not limited too much here. Based on this, it is possible to support low-noise amplification processing of RF signals of at least two different frequency bands at the same time, thereby supporting the simultaneous reception of RF signals of at least two different frequency bands.

[0072] The control module 30 is also used to control the target power module 201 to provide a power supply voltage according to the gain information of the target low noise amplifier module 102 when the radio frequency system operates in the MIMO (Multiple Input Multiple Output) mode, so as to simultaneously power the target low noise amplifier module 102 and at least one low noise amplifier module 40. In this embodiment, the MIMO mode can be understood as the radio frequency system supporting the reception of radio frequency signals in at least two different frequency bands. Exemplarily, the control module 30 is also used to control the remaining power modules 20 to provide a power supply voltage when the radio frequency system operates in the single connection mode and the MIMO mode, and to control the target power module 201 to provide a power supply voltage according to the gain information of the target low noise amplifier module 102, so as to simultaneously power the target low noise amplifier module 102 and at least one low noise amplifier module 40, thereby supporting multi-channel reception under single-channel FDD.

[0073] For example, Figure 5 In the RF system shown, the control module 30 can be used to control the second remaining power module 203203 to provide a power supply voltage according to the output power of the power amplifier module 104 when the RF system operates in a single connection mode and a MIMO mode, and to control the target power module 201 to provide a power supply voltage according to the gain information of the target low-noise amplifier module 102, so as to simultaneously power the target low-noise amplifier module 102 and the low-noise amplifier sub-module 40, thereby supporting the transmitting APT mode and the dual-channel receiving APT mode under a single-channel FDD through the second transceiver circuit 12.
