[0044] The embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0045] Without departing from the spirit or scope of the present application, various modifications and variations can be made in the present application, which will be obvious to those skilled in the art. Therefore, the present application is intended to cover the modifications and variations of the present application that fall within the scope of the corresponding claims (claimed technical solutions) and their equivalents. It should be noted that the embodiments provided by the embodiments of the present application can be combined with each other without conflict.

[0046] To make the above objects, features and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0047] As described in the background art section, in the application process of existing electronic devices integrated with radio frequency modules, users wearing hearing aids generally report that there is a "clicking" noise during calls, the call quality is poor, and the user experience is affected.

[0048] To ensure that hearing aid users can use electronic devices without obstacles, some regions have compulsorily implemented the HAC (Hearing Aid Compatibility) certification standard. This certification requires that when the electronic device is in a call, the magnetic field noise intensity generated in the 50mm×50mm area near the earpiece should be lower than -38dB(A / m), and the frequency range is 20Hz - 20kHz. With the expansion of the communication system from traditional 2G / 3G voice scenarios to multi-scenario applications such as 4G VoLTE, 5G VoNR, and UL MIMO, the HAC certification regulations have been continuously upgraded, and the test indicators have become increasingly strict.

[0049] The inventors' research found that users wearing hearing aids generally reported that "clicking" noise interference often accompanied calls, and the root cause was the periodic magnetic field noise generated when the radio frequency module of the electronic device (especially the 5G TDD mode) was working. Specifically, if the radio frequency module of the electronic device switches the transmission and reception states with a period of 5 ms. When the signal is transmitted, the regulation requires that the electronic device transmit the maximum power during the test, and the supply current of the power amplifier (PA) in the radio frequency module will suddenly increase to hundreds of mA, while the current of the power amplifier (PA) is almost zero during reception. This periodic current change (the difference can reach hundreds of mA) generates an alternating magnetic field through the wire, thereby generating a magnetic field noise of 1 / 5 ms × 1000 = 200 Hz. Moreover, the greater this periodic current change, the greater the intensity of the alternating magnetic field noise generated through the wire.

[0050] It should be noted that the supply currents of other devices such as transceivers in the radio frequency module are small, and the influence on the magnetic field is limited. Due to the large supply current of the power amplifier, it becomes the main source of magnetic field noise. Although existing solutions attempt to optimize the motherboard layout (such as side bar-shaped board and C-shaped board designs) to keep the power amplifier and power supply away from the earpiece area, such as concentrating them on the side or bottom of the electronic device, such designs result in a reduced utilization rate of the motherboard space and the battery capacity is limited due to the narrowing of the battery width.

[0051] Therefore, how to improve the call quality of the electronic device and make it meet the HAC certification without reducing the motherboard space utilization rate and without reducing the battery capacity is a research direction for those skilled in the art.

[0052] In view of this, the embodiments of the present application provide a radio frequency module, which is applied to an electronic device that can be compatible with hearing aids, such as Figure 1 As shown, the radio frequency module includes:

[0053] At least one radio frequency front-end module, the at least one radio frequency front-end module includes a first radio frequency front-end module 10, the first radio frequency front-end module 10 includes a first radio frequency front-end module 11, the first radio frequency front-end module 11 transmits a signal in a first frequency band in a first time period and receives a signal in the first frequency band in a second time period, and the first time period and the second time period are different;

[0054] A transceiver element 20, the transceiver element 20 is used to provide a radio frequency signal for the at least one radio frequency front-end module or receive the radio frequency signal received by the at least one radio frequency front-end module;

[0055] A power supply element 30, the power supply element 30 includes at least one power supply module 31, and the power supply module 31 is used to provide a power supply signal for its corresponding radio frequency front-end module.

[0056] It should be noted that, in this embodiment, during the first time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 provides drive current for a first number of power amplifiers in the first radio frequency front-end module 10. During the second time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 provides drive current for a second number of power amplifiers in the first radio frequency front-end module 10. The first number is the same as the second number. Thus, during the signal transmission stage and the signal reception stage of the first radio frequency front-end module 10, its power supply module 31 provides drive current for the same number of power amplifiers, thereby reducing the difference in the supply current output by its power supply module 31 when the first radio frequency front-end module 10 switches between the signal transmission stage and the signal reception stage, reducing the difference in the supply current output by the power supply element 30 during the process of the radio frequency module periodically switching between the transmission state and the reception state, and further reducing the magnetic field intensity generated by the difference in the supply current output by this power supply element 30, reducing the call interference to the electronic device to which this radio frequency module is applied, enabling it to meet the HAC certification, and improving the user experience.

[0057] It should be noted that, in the embodiment of the present application, since the supply current output by the power supply element 30 changes little during the process of the radio frequency module periodically switching between the transmission state and the reception state, and the generated magnetic field noise is small, it can meet the HAC certification. Therefore, in the embodiment of the present application, there are fewer restrictions on the installation position of the radio frequency module in the electronic device, the space of the main board can be fully utilized, which is beneficial to improving the space utilization rate of the main board and the battery capacity.

[0058] Optionally, in an embodiment of the present application, continuing as Figure 1 shown, the first radio frequency front-end module 11 includes a first signal transmission branch TX1 and a first signal reception branch RX1. The first signal transmission branch TX1 includes a first power amplifier PA1, and the first signal reception branch RX1 includes a first low noise amplifier LNA1. It should be noted that, in this embodiment, the supply current required by the first power amplifier PA1 is relatively large, the supply current required by the first low noise amplifier LNA1 is relatively small, and the difference between the two is several hundred milliamperes, while the static current of the first power amplifier PA1 is about 400 milliamperes.

[0059] Therefore, in an embodiment of the present application, during the first time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 supplies drive current to the first power amplifier PA1, and the transceiver element 20 supplies a radio frequency signal to the first power amplifier PA1 to transmit the radio frequency signal through the first power amplifier PA1; during the second time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 supplies drive current to the first power amplifier PA1, and the transceiver element 20 stops supplying the radio frequency signal to the first power amplifier PA1, so that the first power amplifier PA1 is in a powered state but does not receive a radio frequency signal, that is, the first power amplifier PA1 is in a static state. It can be seen that in this embodiment, the power supply module 31 corresponding to the first radio frequency front-end module 10 supplies drive current to the first power amplifier PA1 both in the first time period and in the second time period. Thus, when the first radio frequency front-end module 11 periodically switches between the signal transmission state and the signal reception state, the difference in the supply current output by the power supply module 31 corresponding to the first radio frequency front-end module 10 is small, thereby reducing the magnetic field intensity generated by the difference in the supply current output by the power supply module 31, reducing the call interference to the electronic device to which the radio frequency module is applied, enabling it to meet the HAC certification, and improving the user experience.

[0060] Based on any of the above embodiments, in an embodiment of the present application, as Figure 2 shown, the first radio frequency front-end module 10 further includes a second radio frequency front-end module 12. It should be noted that the second radio frequency front-end module 12 and the first radio frequency front-end module 11 operate in a time-sharing manner, that is, the operating times of the first radio frequency front-end module 11 and the second radio frequency front-end module 12 do not overlap. Optionally, in this embodiment, the second radio frequency front-end module 12 includes a second signal transmission branch TX2, and the second signal transmission branch TX2 includes a second power amplifier PA2. The power supply module 31 corresponding to the first radio frequency front-end module 11 is further configured to supply drive current to the second radio frequency front-end module 12.

[0061] It should be noted that, in this embodiment, continuing as Figure 1 shown, different radio frequency front-end modules in the same radio frequency front-end module, such as the first radio frequency front-end module 11 and the second radio frequency front-end module 12 in the first radio frequency front-end module 10, transmit and receive radio frequency signals through the same transceiver element 20 and are signal-connected to the same antenna 50 through the same radio frequency switch 40 to achieve the transmission and reception of radio frequency signals.

[0062] Based on the above embodiments, in an embodiment of the present application, in the first time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 provides drive current to the first power amplifier PA1, and does not provide drive current to the second power amplifier PA2 and the first low-noise amplifier LNA1; in the second time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 does not provide drive current to the first power amplifier PA1, and provides drive current to the second power amplifier PA2 and the first low-noise amplifier LNA1.

[0063] Specifically, in the first time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 provides drive current to the first power amplifier PA1, and the transceiver element 20 provides a radio frequency signal to the first power amplifier PA1 to transmit the radio frequency signal through the first power amplifier PA1, but does not provide drive current to the first low-noise amplifier LNA1 and the second power amplifier PA2, so that the first low-noise amplifier LNA1 and the second power amplifier PA2 are in the off state;

[0064] In the second time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 does not provide drive current to the first power amplifier PA1, so that the first power amplifier PA1 is in the off state, but provides drive current to the second power amplifier PA2 and the first low-noise amplifier LNA1. At this time, the transceiver element 20 receives the radio frequency signal output by the first low-noise amplifier LNA1, and does not provide a radio frequency signal to the second power amplifier PA2, so that the first signal receiving branch RX1 where the first low-noise amplifier LNA1 is located is used to transmit signals, and the second signal transmitting branch TX2 where the second power amplifier PA2 is located is not used to transmit signals.

[0065] It can be seen that in this embodiment, in the first radio frequency front-end module 10, in the first time period, only the first power amplifier PA1 is powered, and the second power amplifier PA2 is not powered. In the second time period, the first power amplifier PA1 is not powered, and the second power amplifier PA2 is powered. That is, in the first time period and the second time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 provides drive current to the same number of power amplifiers, thereby reducing the difference in the supply current output by the power supply module 31 when the first radio frequency front-end module 10 switches between the signal transmission stage and the signal reception stage, and reducing the difference in the supply current output by the power supply element 30 during the periodic switching of the radio frequency module between the transmission state and the reception state. Furthermore, the magnetic field intensity generated by the difference in the supply current output by the power supply element 30 is reduced, and the call interference to the electronic device to which the radio frequency module is applied is reduced, so that it meets the HAC certification and improves the user experience.

[0066] In another embodiment of the present application, during the first time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 supplies driving current to the first power amplifier PA1, and does not supply driving current to the second power amplifier PA2 and the first low-noise amplifier LNA1; during the second time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 does not supply driving current to the second power amplifier PA2, and supplies driving current to the first power amplifier PA1 and the first low-noise amplifier LNA1.

[0067] Specifically, during the first time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 supplies driving current to the first power amplifier PA1, and the transceiver element 20 supplies a radio frequency signal to the first power amplifier PA1 to transmit the radio frequency signal through the first power amplifier PA1, but does not supply driving current to the first low-noise amplifier LNA1 and the second power amplifier PA2, so that the first low-noise amplifier LNA1 and the second power amplifier PA2 are in the off state;

[0068] During the second time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 supplies driving current to the first power amplifier PA1 and the first low-noise amplifier LNA1, and does not supply driving current to the second power amplifier PA2, so that the second power amplifier PA2 is in the off state. At this time, the transceiver element 20 receives the radio frequency signal output by the first low-noise amplifier LNA1, and does not supply a radio frequency signal to the first power amplifier PA1, so that the first signal receiving branch RX1 where the first low-noise amplifier LNA1 is located is used to transmit the signal, and the second signal transmitting branch TX2 where the first power amplifier PA1 is located is not used to transmit the signal.

[0069] It can be seen that in this embodiment, in the first radio frequency front-end module 10, during the first time period and the second time period, only the first power amplifier PA1 is powered, and the second power amplifier PA2 is not powered. That is, during the first time period and the second time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 supplies driving current to the same number of power amplifiers, thereby reducing the difference in the supply current output by the power supply module 31 when the first radio frequency front-end module 10 switches between the signal transmission stage and the signal reception stage, reducing the difference in the supply current output by the power supply element 30 during the process of the radio frequency module periodically switching between the transmission state and the reception state, and further reducing the magnetic field intensity generated by the difference in the supply current output by the power supply element 30, reducing the call interference to the electronic device to which the radio frequency module is applied, enabling it to meet the HAC certification, and improving the user experience.

[0070] Optionally, in an embodiment of the present application, continue asFigure 2 As shown, the second radio frequency front-end module 12 further includes a second signal receiving branch RX2. In the third time period, the second signal transmitting branch TX2 transmits a signal in a second frequency band, and the second signal receiving branch RX2 receives a signal in a third frequency band. The second frequency band and the third frequency band are different. That is, in this embodiment, the second radio frequency front-end module 12 adopts the principle of frequency division duplex to transmit and receive signals simultaneously, but the frequency of the transmitted signal is different from the frequency of the received signal.

[0071] Optionally, in an embodiment of the present application, continuing as Figure 2 shown, the second signal transmitting branch TX2 and the second signal receiving branch RX2 are connected to the same radio frequency switch 40 through a duplexer 121.

[0072] In another embodiment of the present application, the second radio frequency front-end module 12 further includes a second signal receiving branch RX2. In the third time period, the second signal transmitting branch TX2 transmits a signal in a second frequency band. In the fourth time period, the second signal receiving branch RX2 receives the signal in the second frequency band. The third time period and the fourth time period are different time periods. That is, in this embodiment, the second radio frequency front-end module 12 adopts the principle of time division duplex to transmit and receive signals in different time periods, and the frequency of the transmitted signal is the same as the frequency of the received signal.

[0073] It should be noted that when the second radio frequency front-end module 12 transmits and receives signals in different time periods, the second signal transmitting branch TX2 has a second power amplifier PA2, and the second signal receiving branch RX2 does not have a power amplifier, which easily causes a large difference in the output current of the power supply module 31 corresponding to the first radio frequency front-end module 10. Therefore, in this embodiment, in the fourth time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 also provides drive current to the first power amplifier PA1 or the second power amplifier PA2, so that in the third time period when the second signal transmitting branch TX2 transmits a signal and the fourth time period when the second signal receiving branch RX2 receives a signal, the number of power amplifiers powered by the power supply module 31 corresponding to the first radio frequency front-end module 10 is the same.

[0074] Based on any of the above embodiments, in an embodiment of the present application, the radio frequency module may further include at least two radio frequency front-end modules, and the present application does not limit this, which depends on the specific situation. Optionally, in an embodiment of the present application, when the radio frequency module includes at least two radio frequency front-end modules, the structures in each radio frequency front-end module may be the same as the structure of the first radio frequency front-end module provided in any of the above embodiments, and the present application will not elaborate on this again.

[0075] Optionally, in an embodiment of the present application, when the RF module includes multiple RF front-end modules, the power supply element 30 includes multiple power supply modules, and different RF front-end modules are powered by different power supply modules. Different power supply modules can be powered by the same battery; the multiple RF front-end modules share the same transceiver element 20, the same RF switch 40, and the same antenna 50. However, the present application does not limit this, and it depends on the specific situation.

[0076] Correspondingly, an embodiment of the present application further provides an electronic device, which can be compatible with a hearing aid device. In this embodiment, the electronic device includes an RF module, and as shown in Figure 1 below, the RF module includes:

[0077] At least one RF front-end module, where the at least one RF front-end module includes a first RF front-end module 10, and the first RF front-end module 10 includes: a first RF front-end module 11, which transmits a signal in a first frequency band in a first time period and receives the signal in the first frequency band in a second time period, and the first time period and the second time period are different;

[0078] A transceiver element 20, which is used to provide an RF signal for the at least one RF front-end module or receive the RF signal received by the at least one RF front-end module;

[0079] A power supply element 30, which includes at least one power supply module, and the power supply module is used to provide a power supply signal for its corresponding RF front-end module.

[0080] It should be noted that in this embodiment, in the first time period, the power supply module 31 corresponding to the first RF front-end module 10 provides drive current for the first number of power amplifiers in the first RF front-end module 10. In the second time period, the power supply module 31 corresponding to the first RF front-end module 10 provides drive current for the second number of power amplifiers in the first RF front-end module 10. The first number and the second number are the same, so that in the signal transmission stage and the signal reception stage of the first RF front-end module 10, its power supply module 31 provides drive current for the same number of power amplifiers, thereby reducing the difference in the power supply current output by its power supply module 31 when the first RF front-end module 10 switches between the signal transmission stage and the signal reception stage, reducing the difference in the power supply current output by the power supply element 30 during the process of the RF module periodically switching between the transmission state and the reception state, and further reducing the magnetic field intensity generated by the difference in the power supply current output by the power supply element 30, reducing the call interference of the electronic device to which the RF module is applied, enabling it to meet the HAC certification, and improving the user experience.

[0081] It should be noted that in the embodiments of the present application, since the supply current output by the power supply element 30 changes little during the process of periodically switching between the transmitting state and the receiving state of the radio frequency module, the generated magnetic field noise is small and can meet the HAC certification. Therefore, in the embodiments of the present application, there are fewer restrictions on the installation position of the radio frequency module in the electronic device, the space of the main board can be fully utilized, which is beneficial to improving the space utilization rate of the main board and the battery capacity.

[0082] Optionally, in an embodiment of the present application, the first radio frequency front-end module 11 includes a first signal transmitting branch TX1 and a first signal receiving branch RX1. The first signal transmitting branch TX1 includes a first power amplifier PA1, and the first signal receiving branch RX1 includes a first low-noise amplifier LNA1. In an embodiment of the present application, during the first time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 provides a driving current to the first power amplifier PA1, and the transceiver element 20 provides a radio frequency signal to the first power amplifier PA1 to transmit the radio frequency signal through the first power amplifier PA1; during the second time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 provides a driving current to the first power amplifier PA1, and the transceiver element 20 stops providing a radio frequency signal to the first power amplifier PA1, so that the first power amplifier PA1 is in a powered state but does not receive a radio frequency signal, that is, the first power amplifier PA1 is in a static state. It can be seen that in this embodiment, the power supply module 31 corresponding to the first radio frequency front-end module 10 provides a driving current to the first power amplifier PA1 both during the first time period and during the second time period. Therefore, when the first radio frequency front-end module 11 periodically switches between the signal transmitting state and the signal receiving state, the difference in the supply current output by its power supply module 31 is small, thereby reducing the magnetic field intensity generated by the difference in the supply current output by this power supply module 31, reducing the call interference to the electronic device to which this radio frequency module is applied, enabling it to meet the HAC certification, and improving the user experience.

[0083] Based on any of the above embodiments, in an embodiment of the present application, the first radio frequency front-end module 10 further includes a second radio frequency front-end module 12. It should be noted that the second radio frequency front-end module 12 and the first radio frequency front-end module 11 work in a time-sharing manner, that is, the working times of the first radio frequency front-end module 11 and the second radio frequency front-end module 12 do not overlap. Optionally, in this embodiment, the second radio frequency front-end module 12 includes a second signal transmitting branch TX2, and the second signal transmitting branch TX2 includes a second power amplifier PA2. The power supply module corresponding to the first radio frequency front-end module 10 is further used to provide a driving current to the second radio frequency front-end module 12.

[0084] Based on the above embodiments, in an embodiment of the present application, in the first time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 provides drive current to the first power amplifier PA1 and does not provide drive current to the second power amplifier PA2 and the first low-noise amplifier LNA1; in the second time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 does not provide drive current to the first power amplifier PA1 and provides drive current to the second power amplifier PA2 and the first low-noise amplifier LNA1.

[0085] It can be seen that in this embodiment, in the first radio frequency front-end module 10, in the first time period, only the first power amplifier PA1 is powered, and the second power amplifier PA2 is not powered. In the second time period, the first power amplifier PA1 is not powered, and the second power amplifier PA2 is powered. That is, in the first time period and the second time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 provides drive current to the same number of power amplifiers, thereby reducing the difference in the supply current output by the power supply module 31 when the first radio frequency front-end module 10 switches between the signal transmission stage and the signal reception stage, and reducing the difference in the supply current output by the power supply element 30 during the process of the radio frequency module periodically switching between the transmission state and the reception state. Furthermore, the magnetic field intensity generated by the difference in the supply current output by the power supply element 30 is reduced, and the call interference to the electronic device to which the radio frequency module is applied is reduced, so that it meets the HAC certification and improves the user experience.

[0086] In another embodiment of the present application, in the first time period, the power supply module corresponding to the first radio frequency front-end module 10 provides drive current to the first power amplifier PA1 and does not provide drive current to the second power amplifier PA2 and the first low-noise amplifier LNA1; in the second time period, the power supply module corresponding to the first radio frequency front-end module 10 does not provide drive current to the second power amplifier PA2 and provides drive current to the first power amplifier PA1 and the first low-noise amplifier LNA1.

[0087] It can be seen that in this embodiment, in the first radio frequency front-end module 10, only the first power amplifier PA1 is powered in the first time period and the second time period, and the second power amplifier PA2 is not powered. That is, in the first time period and the second time period, the power supply module 31 corresponding to the first radio frequency front-end module 10 supplies drive current to the same number of power amplifiers, thereby reducing the difference in the supply current output by the power supply module 31 of the first radio frequency front-end module 10 when switching between the signal transmission stage and the signal reception stage, and reducing the difference in the supply current output by the power supply element 30 during the process of the radio frequency module periodically switching between the transmission state and the reception state. Furthermore, the magnetic field intensity generated by the difference in the supply current output by the power supply element 30 is reduced, and the call interference of the electronic device to which the radio frequency module is applied is reduced, so as to meet the HAC certification and improve the user experience.

[0088] Optionally, in an embodiment of the present application, continuing as Figure 2 shown, the second radio frequency front-end module 12 further includes a second signal receiving branch RX2. In the third time period, the second signal transmitting branch TX2 transmits a signal in a second frequency band, and the second signal receiving branch RX2 receives a signal in a third frequency band. The second frequency band and the third frequency band are different. That is, in this embodiment, the second radio frequency front-end module 12 adopts the principle of frequency division duplexing to transmit and receive signals simultaneously, but the frequency of the transmitted signal is different from the frequency of the received signal.

[0089] In another embodiment of the present application, the second radio frequency front-end module 12 further includes a second signal receiving branch RX2. In the third time period, the second signal transmitting branch TX2 transmits a signal in a second frequency band, and in the fourth time period, the second signal receiving branch RX2 receives the signal in the second frequency band. The third time period and the fourth time period are different time periods. That is, in this embodiment, the second radio frequency front-end module 12 adopts the principle of time division duplexing to transmit and receive signals in different time periods, and the frequency of the transmitted signal is the same as the frequency of the received signal.

[0090] It should be noted that when the second radio frequency front-end module 12 transmits and receives signals in different time periods, the second signal transmitting branch TX2 has a second power amplifier PA2, and there is no power amplifier in the second signal receiving branch RX2, which easily leads to a large difference in the output current of the power supply module. Therefore, in this embodiment, in the fourth time period, the power supply module corresponding to the first radio frequency front-end module 10 also supplies drive current to the first power amplifier PA1 or the second power amplifier PA2, so that the number of power amplifiers powered by the power supply module corresponding to the first radio frequency front-end module 10 is the same in the third time period when the second signal transmitting branch TX2 transmits a signal and the fourth time period when the second signal receiving branch RX2 receives a signal.

[0091] Optionally, based on any of the above embodiments, in an embodiment of the present application, as Figure 3 shown, the at least one radio frequency front-end module further includes a second radio frequency front-end module 60. There is a first distance between the first radio frequency front-end module 10 and the earpiece of the electronic device, and there is a second distance between the second radio frequency front-end module 60 and the earpiece of the electronic device. The first distance is less than the second distance. By setting the second radio frequency front-end module 60 at a position farther from the earpiece of the electronic device, the magnetic field noise generated during the operation of the second radio frequency front-end module 60 is reduced from interfering with the signal transmitted by the earpiece, thereby improving the user experience.

[0092] It should be noted that since the second radio frequency front-end module is set at a position farther from the earpiece of the electronic device, the magnetic field noise generated during the operation of the second radio frequency front-end module has less interference with the signal transmitted by the earpiece.

[0093] Therefore, in an optional embodiment of the present application, the second radio frequency front-end module includes: a third radio frequency front-end module. The third radio frequency front-end module transmits a signal in a fourth frequency band during a fifth time period and receives the signal in the fourth frequency band during a sixth time period, and the fifth time period and the sixth time period are different; in this embodiment, during the fifth time period, the power supply module corresponding to the second radio frequency front-end module provides drive current for a third number of power amplifiers in the second radio frequency front-end module, and during the sixth time period, the power supply module corresponding to the second radio frequency front-end module provides drive current for a fourth number of power amplifiers in the second radio frequency front-end module, and the third number and the fourth number are different. That is, during the fifth time period, the power supply module corresponding to the second radio frequency front-end module provides drive current for the power amplifiers in the third radio frequency front-end module, and during the sixth time period, the power supply module corresponding to the second radio frequency front-end module does not provide drive current for the power amplifiers in the second radio frequency front-end module, so as to reduce the power consumption of the power supply module.

[0094] In another embodiment of the present application, the second radio frequency front-end module includes: a third radio frequency front-end module, which transmits a signal in the fourth frequency band during a fifth time period and receives the signal in the fourth frequency band during a sixth time period, where the fifth time period and the sixth time period are different; in this embodiment, during the fifth time period, the power supply module corresponding to the second radio frequency front-end module provides drive current for a third number of power amplifiers in the second radio frequency front-end module, and during the sixth time period, the power supply module corresponding to the second radio frequency front-end module provides drive current for a fourth number of power amplifiers in the second radio frequency front-end module, and the third number and the fourth number are the same, that is, during the fifth time period, the power supply module corresponding to the second radio frequency front-end module provides drive current for the power amplifiers in the third radio frequency front-end module, and during the sixth time period, the power supply module corresponding to the second radio frequency front-end module also provides drive current for the power amplifiers in the second radio frequency front-end module, so as to further reduce the interference of the magnetic field noise generated during the operation of the second radio frequency front-end module on the signal transmitted by the receiver and improve the user experience.

[0095] Optionally, based on any of the above embodiments, in an embodiment of the present application, the third radio frequency front-end module includes: a third signal transmission branch and a third signal reception branch, where the third signal transmission branch includes a third power amplifier, and the third signal reception branch includes a second low-noise amplifier. In an embodiment of the present application, during a fifth time period, the power supply module corresponding to the second radio frequency front-end module provides drive current for the third power amplifier, and the transceiver element provides a radio frequency signal for the third power amplifier to transmit the radio frequency signal through the third power amplifier; during a sixth time period, the power supply module corresponding to the second radio frequency front-end module provides drive current for the second low-noise amplifier, and the transceiver element receives the radio frequency signal received by the second low-noise amplifier.

[0096] Based on the above embodiments, in an embodiment of the present application, during a sixth time period, the power supply module corresponding to the second radio frequency front-end module does not provide drive current for the third power amplifier, so that the number of power amplifiers powered in the second radio frequency front-end module is different during the fifth time period and the sixth time period, so as to reduce the power consumption of the power supply element; in another embodiment of the present application, during a sixth time period, the power supply module corresponding to the second radio frequency front-end module also provides drive current for the third power amplifier, but during the sixth time period, the transceiver element does not provide a radio frequency signal for the third power amplifier, so that the number of power amplifiers powered in the second radio frequency front-end module is the same during the fifth time period and the sixth time period, further reducing the interference of the magnetic field noise generated during the operation of the second radio frequency front-end module on the signal transmitted by the receiver and improving the user experience.

[0097] In another embodiment of the present application, the second radio frequency front-end module further includes a fourth radio frequency front-end module. It should be noted that the fourth radio frequency front-end module and the third radio frequency front-end module operate in a time-sharing manner, that is, the operating times of the third radio frequency front-end module and the fourth radio frequency front-end module do not overlap. Optionally, in this embodiment, the fourth radio frequency front-end module includes a fourth signal transmitting branch, and the fourth signal transmitting branch includes a fourth power amplifier. The power supply module corresponding to the second radio frequency front-end module is further configured to provide drive current to the fourth radio frequency front-end module.

[0098] Based on the above embodiments, in an embodiment of the present application, in the fifth time period, the power supply module corresponding to the second radio frequency front-end module provides drive current to the third power amplifier, and does not provide drive current to the fourth power amplifier and the second low-noise amplifier, so as to realize the transmission of radio frequency signals in the fourth frequency band; in the sixth time period, the power supply module corresponding to the second radio frequency front-end module does not provide drive current to the third power amplifier, and provides drive current to the fourth power amplifier and the second low-noise amplifier, so as to realize the reception of radio frequency signals in the fourth frequency band.

[0099] It can be seen that in this embodiment, in the second radio frequency front-end module, in the fifth time period, only the third power amplifier is powered, and the fourth power amplifier is not powered. In the sixth time period, the third power amplifier is not powered, and the fourth power amplifier is powered. That is, in the fifth time period and the sixth time period, the power supply module corresponding to the second radio frequency front-end module provides drive current to the same number of power amplifiers, thereby reducing the difference in the supply current output by the power supply module of the second radio frequency front-end module when switching between the signal transmission stage and the signal reception stage, reducing the difference in the supply current output by the power supply component during the periodic switching of the radio frequency module between the transmission state and the reception state, and further reducing the magnetic field intensity generated by the difference in the supply current output by the power supply component, reducing the call interference to the electronic device to which the radio frequency module is applied, enabling it to meet the HAC certification, and improving the user experience.

[0100] Different from the above embodiments, when the third quantity and the fourth quantity are different, in the sixth time period, the power supply module corresponding to the second radio frequency front-end module only provides drive current to the second low-noise amplifier and does not provide drive current to the fourth power amplifier.

[0101] In another embodiment of the present application, in the fifth time period, the power supply module corresponding to the second radio frequency front-end module supplies drive current to the third power amplifier and does not supply drive current to the fourth power amplifier and the second low-noise amplifier; in the sixth time period, the power supply module corresponding to the second radio frequency front-end module does not supply drive current to the fourth power amplifier and supplies drive current to the third power amplifier and the second low-noise amplifier.

[0102] It can be seen that in this embodiment, in the second radio frequency front-end module, in the fifth time period and the sixth time period, only the third power amplifier is powered, and the fourth power amplifier is not powered. That is, in the fifth time period and the sixth time period, the power supply module corresponding to the second radio frequency front-end module supplies drive current to the same number of power amplifiers, thereby reducing the difference in the supply current output by the power supply module when the second radio frequency front-end module switches between the signal transmission stage and the signal reception stage, and reducing the difference in the supply current output by the power supply component during the process of the radio frequency module periodically switching between the transmission state and the reception state. Furthermore, the magnetic field intensity generated by the difference in the supply current output by the power supply component is reduced, and the call interference to the electronic device to which the radio frequency module is applied is reduced, so that it meets the HAC certification and improves the user experience.

[0103] Different from the above embodiment, when the third quantity and the fourth quantity are different, in the sixth time period, the power supply module corresponding to the second radio frequency front-end module only supplies drive current to the second low-noise amplifier and does not supply drive current to the third power amplifier.

[0104] Based on any of the above embodiments, in an embodiment of the present application, the fourth radio frequency front-end module further includes a fourth signal reception branch. In the seventh time period, the fourth signal transmission branch transmits a signal in the fifth frequency band, and the fourth signal reception branch receives a signal in the sixth frequency band. The fifth frequency band and the sixth frequency band are different. That is, in this embodiment, the fourth radio frequency front-end module uses the principle of frequency-division duplexing to transmit and receive signals simultaneously, but the frequency of the transmitted signal and the frequency of the received signal are different.

[0105] In another embodiment of the present application, the fourth radio frequency front-end module further includes a fourth signal reception branch. In the seventh time period, the fourth signal transmission branch transmits a signal in the fifth frequency band, and in the eighth time period, the fourth signal reception branch receives the signal in the fifth frequency band. The seventh time period and the eighth time period are different time periods. That is, in this embodiment, the fourth radio frequency front-end module uses the principle of time-division duplexing to transmit and receive signals in different time periods, and the frequency of the transmitted signal and the frequency of the received signal are the same.

[0106] It should be noted that when the fourth radio frequency front - end module transmits and receives signals in different time periods, there is a fourth power amplifier in the fourth signal transmission branch, and there is no power amplifier in the fourth signal reception branch, which easily leads to a large difference in the output current of its corresponding power supply module. Therefore, in this embodiment, in the eighth time period, the power supply module corresponding to the second radio frequency front - end module also provides drive current to the third power amplifier or the fourth power amplifier, so that in the third time period when the fourth signal transmission branch transmits signals and the fourth time period when the fourth signal reception branch receives signals, the number of power amplifiers powered by the power supply module corresponding to the second radio frequency front - end module is the same. However, the present application does not limit this. In other embodiments of the present application, in the third time period when the fourth signal transmission branch transmits signals and the fourth time period when the fourth signal reception branch receives signals, the number of power amplifiers powered by the power supply module corresponding to the second radio frequency front - end module may also be different, depending on the specific situation.

[0107] In other embodiments of the present application, the radio frequency module may include more radio frequency front - end modules. Other radio frequency front - end modules may adopt the same structure as the second radio frequency front - end module in the above - mentioned embodiments. The present application does not limit this, depending on the specific situation.

[0108] Optionally, in an embodiment of the present application, when the radio frequency module includes multiple radio frequency front - end modules, the power supply element 30 includes multiple power supply modules. Different radio frequency front - end modules are powered by different power supply modules, and different power supply modules may be powered by the same battery; the multiple radio frequency front - end modules share the same transceiver element 20, the same radio frequency switch 40, and the same antenna 50. However, the present application does not limit this, depending on the specific situation.

[0109] In addition, the embodiment of the present application also provides a power supply method, as Figure 4 shown. This power supply method includes:

[0110] S1: In the first time period, use the power supply element of the electronic device to provide drive current to the signal transmission branch of the first radio frequency front - end module in the first radio frequency front - end module of the electronic device, and use the transceiver element in the electronic device to provide a radio frequency signal to the signal transmission branch in the first radio frequency front - end module, so as to realize the transmission of signals in the first frequency band. The signal transmission branch includes a power amplifier;

[0111] S2: In the second time period, use a power supply component to provide a drive current to a signal receiving branch in a first radio frequency front-end module of an electronic device, and use a transceiver component in the electronic device to receive a radio frequency signal output from the signal receiving branch in the first radio frequency front-end module, so as to receive a signal in a first frequency band, and provide a drive current to a power amplifier in the first radio frequency front-end module. However, the transceiver component does not provide a radio frequency signal to the power amplifier in the first radio frequency front-end module. The first time period and the second time period are different;

[0112] In the first time period, the number of power amplifiers in the first radio frequency front-end module in a driving state is the same as the number of power amplifiers in the first radio frequency front-end module in a driving state in the second time period, so that in the signal transmission stage and the signal reception stage of the first radio frequency front-end module, the corresponding power supply module in the power supply component provides a drive current to the same number of power amplifiers, thereby reducing the difference in the supply current output by its power supply module when the first radio frequency front-end module switches between the signal transmission stage and the signal reception stage, reducing the difference in the supply current output by the power supply component during the process of the radio frequency module periodically switching between the transmission state and the reception state, and further reducing the magnetic field intensity generated by the difference in the supply current output by the power supply component, reducing the call interference of the electronic device to which the radio frequency module is applied, enabling it to meet the HAC certification, and improving the user experience.

[0113] It should be noted that in the embodiment of the present application, since the supply current output by the power supply component changes little during the process of the radio frequency module periodically switching between the transmission state and the reception state, and the generated magnetic field noise is small and can meet the HAC certification, therefore, in the embodiment of the present application, the setting position of the radio frequency module in the electronic device has less restrictions, the space of the main board can be fully utilized, which is beneficial to improving the space utilization rate of the main board and the battery capacity.

[0114] Based on the above embodiment, in an embodiment of the present application, in the second time period, use a power supply component to provide a drive current to a signal receiving branch in a first radio frequency front-end module of an electronic device, and use a transceiver component in the electronic device to receive a radio frequency signal output from the signal receiving branch in the first radio frequency front-end module, so as to receive a signal in a first frequency band, and provide a drive current to a power amplifier in the first radio frequency front-end module. However, the transceiver component does not provide a radio frequency signal to the power amplifier in the first radio frequency front-end module includes:

[0115] In a second time period, a power supply module in the power supply component that powers the first radio frequency front-end module is used to provide a drive current to a signal receiving branch in a first radio frequency front-end module of the electronic device, and a transceiver component in the electronic device is used to receive a radio frequency signal output from the signal receiving branch in the first radio frequency front-end module, so as to implement reception of a signal in a first frequency band, and to provide a drive current to a power amplifier in the first radio frequency front-end module. However, the transceiver component does not provide a radio frequency signal to the power amplifier in the first radio frequency front-end module, so that in a signal transmission stage and a signal reception stage of the first radio frequency front-end module, the corresponding power supply module in the power supply component provides drive currents to the same number of power amplifiers, thereby reducing the difference in the supply current output by its power supply module when the first radio frequency front-end module switches between the signal transmission stage and the signal reception stage, reducing the difference in the supply current output by the power supply component during the process of the radio frequency module periodically switching between the transmission state and the reception state, and further reducing the magnetic field strength generated by the difference in the supply current output by the power supply component, reducing the call interference to the electronic device to which the radio frequency module is applied, enabling it to meet the HAC certification, and improving the user experience.

[0116] In another embodiment of the present application, in a second time period, a power supply component is used to provide a drive current to a signal receiving branch in a first radio frequency front-end module of the electronic device, and a transceiver component in the electronic device is used to receive a radio frequency signal output from the signal receiving branch in the first radio frequency front-end module, so as to implement reception of a signal in a first frequency band, and to provide a drive current to a power amplifier in the first radio frequency front-end module. However, the transceiver component does not provide a radio frequency signal to the power amplifier in the first radio frequency front-end module, and this includes:

[0117] In a second time period, a power supply module that powers the first radio frequency front-end module in the power supply component is used to provide a driving current to a signal receiving branch in a first radio frequency front-end module of the electronic device, and a transceiver component in the electronic device is used to receive a radio frequency signal output from the signal receiving branch in the first radio frequency front-end module, so as to receive a signal in a first frequency band, and to provide a driving current to a power amplifier in a second radio frequency front-end module of the first radio frequency front-end module. However, the transceiver component does not provide a radio frequency signal to the power amplifier in the second radio frequency front-end module, so that in a signal transmission stage and a signal reception stage of the first radio frequency front-end module, a power supply module corresponding thereto in the power supply component provides a driving current to the same number of power amplifiers, thereby reducing a difference in the supply current output by the power supply module when the first radio frequency front-end module switches between the signal transmission stage and the signal reception stage, reducing a difference in the supply current output by the power supply component during a process in which the radio frequency module periodically switches between a transmission state and a reception state, and further reducing a magnetic field intensity generated by the difference in the supply current output by the power supply component, reducing call interference to the electronic device to which the radio frequency module is applied, enabling it to meet HAC certification, and improving user experience.

[0118] Based on the above embodiments, in an embodiment of the present application, the power supply method further includes:

[0119] In a third time period, a power supply module corresponding to the first radio frequency front-end module is used to provide a driving current to both a signal transmission branch and a signal receiving branch in the second radio frequency front-end module, and a transceiver component of the electronic device is used to provide a radio frequency signal in a second frequency band to the signal transmission branch of the second radio frequency front-end module, so as to transmit a radio frequency signal in the second frequency band, and to receive a signal in a third frequency band received by the signal receiving branch in the second radio frequency front-end module, so as to receive a radio frequency signal in the third frequency band, where the second frequency band and the third frequency band are different.

[0120] In another embodiment of the present application, the power supply method further includes:

[0121] In a third time period, a power supply module corresponding to the first radio frequency front-end module is used to provide a driving current to a signal transmission branch in the second radio frequency front-end module, and a transceiver component of the electronic device is used to provide a radio frequency signal in a second frequency band to the signal transmission branch of the second radio frequency front-end module, so as to transmit a radio frequency signal in the second frequency band;

[0122] In the fourth time period, the power supply module corresponding to the first radio frequency front-end module provides drive current to both the signal transmission branch and the signal reception branch in the second radio frequency front-end module, and the transceiver element of the electronic device is used to receive the signal in the second frequency band received by the signal reception branch in the second radio frequency front-end module, so as to realize the reception of the radio frequency signal in the second frequency band. However, the transceiver element of the electronic device does not provide radio frequency signals to the signal transmission branch of the second radio frequency front-end module, so that in the fourth time period, the number of power amplifiers powered by the power supply module corresponding to the first radio frequency front-end module is the same.

[0123] Based on any of the above embodiments, in an embodiment of the present application, the power supply method further includes:

[0124] In the fifth time period, the power supply element of the electronic device provides drive current to the signal transmission branch of the third radio frequency front-end module in the second radio frequency front-end module of the electronic device, and the transceiver element in the electronic device provides radio frequency signals to the signal transmission branch in the third radio frequency front-end module, so as to realize the transmission of signals in the fourth frequency band. The signal transmission branch includes a power amplifier;

[0125] In the sixth time period, the power supply element is used to provide drive current to the signal reception branch in the third radio frequency front-end module of the second radio frequency front-end module of the electronic device, and the transceiver element in the electronic device is used to receive the radio frequency signal output by the signal reception branch in the third radio frequency front-end module, so as to realize the reception of signals in the fourth frequency band. The fifth time period and the sixth time period are different.
