Wi-Fi is mainly used for wireless network coverage in indoor or local areas (such as homes, offices, cafes, airports, etc.). Currently, during the design of electronic devices, the signal transceiver circuit often uses a shared antenna to achieve the transmission of the above-mentioned cellular communication signals and Wi-Fi communication signals.

[0034] 1. In the scenario where the signal transceiver circuit 10 transmits Wi-Fi communication signals:

[0035] The wireless transceiver 13 is used to send a first Wi-Fi communication signal to the first radio frequency front-end module 14 and the second radio frequency front-end module 15 respectively through the Wi-Fi transmission path;

[0036] The first radio frequency front-end module 14 is used to obtain the first Wi-Fi communication signal sent by the wireless transceiver 13 and transmit the first Wi-Fi communication signal through the first antenna 11; or, it is used to enhance the first Wi-Fi communication signal and transmit the enhanced first Wi-Fi communication signal through the first antenna 11.

[0037] The second radio frequency front-end module 15 is used to obtain the first Wi-Fi communication signal sent by the wireless transceiver 13 and transmit the first Wi-Fi communication signal through the second antenna 12; or, it is used to enhance the first Wi-Fi communication signal and transmit the enhanced first Wi-Fi communication signal through the first antenna 11.

[0038] 2. In the scenario where the signal transceiver circuit 10 receives a Wi-Fi communication signal:

[0039] The first radio frequency front-end module 14 is used to obtain the second Wi-Fi communication signal received by the first antenna 11 and send the second Wi-Fi communication signal or the enhanced second Wi-Fi communication signal to the wireless transceiver 13 through the Wi-Fi receiving path; or, it is used to enhance the second Wi-Fi communication signal and send the enhanced second Wi-Fi communication signal to the wireless transceiver 13 through the Wi-Fi receiving path.

[0040] The second radio frequency front-end module 15 is used to obtain the second Wi-Fi communication signal received by the second antenna 12 and send the second Wi-Fi communication signal or the enhanced second Wi-Fi communication signal to the wireless transceiver 13 through the Wi-Fi receiving path; or, it is used to enhance the second Wi-Fi communication signal and send the enhanced second Wi-Fi communication signal to the wireless transceiver 13 through the Wi-Fi receiving path.

[0041] The wireless transceiver 13 is used to receive the second Wi-Fi communication signal or the enhanced second Wi-Fi communication signal sent by the first radio frequency front-end module 14 through the Wi-Fi receiving path, and receive the second Wi-Fi communication signal or the enhanced second Wi-Fi communication signal sent by the second radio frequency front-end module 15 through the Wi-Fi receiving path.

[0042] As Figure 1 shown, the cellular transceiver circuit includes a cellular transceiver 16, a third radio frequency front-end module 17, and a third antenna 18, where:

[0043] 1. In the scenario where the signal transceiver circuit 10 transmits a cellular communication signal:

[0044] The cellular transceiver 16 is used to send the first cellular communication signal to the third radio frequency front-end module 17 through the cellular transmission path.

[0045] The third radio frequency front-end module 17 is configured to obtain the first cellular communication signal sent by the cellular transceiver 16 and transmit the first cellular communication signal through the third antenna 18; or, enhance the first cellular communication signal and transmit the enhanced first cellular communication signal through the third antenna 18.

[0046] 2. In the scenario where the signal transceiver circuit 10 receives a cellular communication signal:

[0047] The third radio frequency front-end module 17 is configured to obtain the second cellular communication signal received by the third antenna 18 and send the second cellular communication signal to the cellular transceiver 16 through the cellular receiving path, or enhance the second cellular communication signal and send the enhanced second cellular communication signal to the cellular transceiver 16 through the cellular receiving path;

[0048] The cellular transceiver 16 is configured to receive the second cellular communication signal or the enhanced second cellular communication signal sent by the third radio frequency front-end module 17 through the cellular receiving path.

[0049] In the related art, the wireless transceiver circuit and the cellular transceiver circuit are completely independent. If it is necessary to transmit cellular communication signals and Wi-Fi communication signals simultaneously, a certain isolation requirement (above 20 - 30 dB) needs to be met between their antennas to prevent mutual radiation crosstalk between the Wi-Fi communication signal (for example, the Wi-Fi communication signal in the 5G band of the Wi-Fi network) and the cellular communication signal (for example, the cellular communication signal in the N79 band of the New Radio (NR) network). However, the space of the electronic device is often limited, making it difficult to meet the above high isolation.

[0050] Figure 2 It is a schematic diagram of another signal transceiver circuit 20 in the related art. As Figure 2 shown, in the related art, the wireless transceiver circuit and the cellular transceiver circuit share the third antenna 18 through the switch unit 29, where:

[0051] 1. In the scenario where the signal transceiver circuit 20 transmits a Wi-Fi communication signal:

[0052] The second radio frequency front-end module 15 is configured to obtain the first Wi-Fi communication signal sent by the wireless transceiver 13 and transmit the first Wi-Fi communication signal through the third antenna 18 when the switch unit 29 conducts the path between the second radio frequency front-end module 15 and the third antenna 18.

[0053] 2. In the scenario where the signal transceiver circuit 20 receives a Wi-Fi communication signal:

[0054] The second radio frequency front-end module 15 is configured to obtain the second Wi-Fi communication signal received by the third antenna 18 when the switch unit 29 turns on the path between the second radio frequency front-end module 15 and the third antenna 18, and send the second Wi-Fi communication signal to the wireless transceiver 13 through the Wi-Fi receiving path, or enhance the second Wi-Fi communication signal and send the enhanced second Wi-Fi communication signal to the wireless transceiver 13 through the Wi-Fi receiving path.

[0055] 3. In the scenario where the signal transceiver circuit 20 transmits a cellular communication signal:

[0056] The third radio frequency front-end module 17 is configured to obtain the first cellular communication signal sent by the cellular transceiver 16, and when the switch unit 29 turns on the path between the third radio frequency front-end module 17 and the third antenna 18, transmit the first cellular communication signal through the third antenna 18, or enhance the first cellular communication signal and transmit the enhanced first cellular communication signal through the third antenna 18 when the switch unit 29 turns on the path between the third radio frequency front-end module 17 and the third antenna 18.

[0057] 4. In the scenario where the signal transceiver circuit 20 receives a cellular communication signal:

[0058] The third radio frequency front-end module 17 is configured to obtain the second cellular communication signal received by the third antenna 18 when the switch unit 29 turns on the path between the third radio frequency front-end module 17 and the third antenna 18, and send the second cellular communication signal to the cellular transceiver 16 through the cellular receiving path, or enhance the second cellular communication signal and send the enhanced second cellular communication signal to the cellular transceiver 16 through the cellular receiving path.

[0059] In the related art, the wireless transceiver circuit and the cellular transceiver circuit share the same antenna, and the switch selects to turn on different paths to work in different time periods. Therefore, the wireless transceiver system and the cellular transceiver system cannot work simultaneously, resulting in that the signal transceiver circuit cannot simultaneously transmit Wi-Fi communication signals and cellular communication signals, and there is a problem of low flexibility in signal transceiver.

[0060] The embodiment of the present application provides a signal transceiver circuit and an electronic device, which realizes the simultaneous transmission of cellular communication signals and Wi-Fi communication signals, improves the flexibility of communication signal transmission, and avoids the mutual interference between cellular communication signals and Wi-Fi communication signals.

[0061] The electronic device involved in the embodiments of the present application may be a mobile phone, a watch, a laptop computer, a handheld computer, a mobile internet device (MID), a personal computer (PC), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in self-driving, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, a personal digital assistant (PDA), etc. The embodiments of the present application do not limit this.

[0062] Exemplarily, Figure 3 FIG. 30 is a schematic diagram of a system architecture of an electronic device provided in an embodiment of the present application.

[0063] As Figure 3 shown, the electronic device includes a processor 31 and a transceiver 32. Optionally, the electronic device may further include a memory 33. The processor 31, the transceiver 32, and the memory 33 may communicate with each other through an internal connection path to transfer data. The memory 33 is used to store a computer program, and the processor 31 is used to call and run the computer program from the memory 33. The above-mentioned processor 31 and the memory 33 may be integrated into a processing device, and more commonly, they are independent components. The processor 31 is used to execute the program code stored in the memory 33 to implement the above functions. Specifically, in implementation, the memory 33 may also be integrated in the processor 31, or independent of the processor 31.

[0064] In addition, in order to make the functions of the electronic device more complete, the electronic device may further include an input unit 35.

[0065] Optionally, the above-mentioned electronic device may further include a power supply 34 for supplying power to various devices or circuits in the electronic device.

For details, please refer to the descriptions in the following method embodiments. To avoid repetition, the detailed descriptions are appropriately omitted here.

[0067] It can be understood that Figure 3The processor 31 in the electronic device shown may include one or more processing units.

[0068] A memory may also be provided in the processor 31 for storing instructions and data. In some embodiments, the memory in the processor 31 is a cache memory. This memory can save the instructions or data that the processor 31 has just used or recycled. If the processor 31 needs to use the instruction or data again, it can directly call it from the memory. This avoids repeated accesses, reduces the waiting time of the processor 31, and thus improves the efficiency of the system.

[0069] It can be understood that Figure 3The power supply 34 shown is used to supply power to the processor 31, the memory 33, the input unit 35, the transceiver 32, etc. The transceiver 32 can provide wireless communication solutions applied to electronic devices, including wireless local area networks (WLANs) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), infrared (IR), etc. The transceiver 32 can be one or more devices integrating at least one communication processing module.

[0070] Figure 4 It is a schematic diagram of a signal transceiver circuit 40 provided by an embodiment of the present application. The signal transceiver circuit 40 includes: a first antenna 41, a wireless transceiver module 42, a cellular transceiver module 43, and a power splitter module 44. The power splitter module 44 is respectively connected to the wireless transceiver module 42, the cellular transceiver module 43, and the first antenna 41. A first transmission path 421 is formed between the first port 441 of the power splitter module 44 and the wireless transceiver module 42, and a second transmission path 431 is formed between the second port 442 of the power splitter module and the cellular transceiver module 43, where:

[0071] The wireless transceiver module 42 is used to send or receive Wi-Fi communication signals in the first frequency band.

[0072] The cellular transceiver module 43 is used to send or receive cellular communication signals in the second frequency band, and the difference between the second frequency band and the first frequency band is less than the difference threshold.

[0073] The first frequency band and the second frequency band can be relatively close communication frequency bands, so the same antenna can be reused for data transmission. Exemplarily, the first frequency band may include the 5G band of the Wi-Fi network, and the second frequency band may include the N79 band of the New Radio (NR) network, but is not limited thereto.

[0074] In some embodiments, the signal transceiver circuit 40 can transmit Wi-Fi communication signals and cellular communication signals simultaneously:

[0075] 1. The signal transceiver circuit 40 transmits Wi-Fi communication signals and cellular communication signals simultaneously:

[0076] The wireless transceiver module 42 is used to send the first Wi-Fi communication signal through the first transmission path 421;

[0077] The cellular transceiver module 43 is used to send the first cellular communication signal through the second transmission path 431;

[0078] The power splitter module 44 is used to obtain the first Wi-Fi communication signal sent by the wireless transceiver module 42 through the first transmission path 421, and obtain the first cellular communication signal sent by the cellular transceiver module 43 through the second transmission path 431, combine the first Wi-Fi communication signal and the first cellular communication signal to obtain a first combined signal, and transmit the first combined signal through the first antenna 41 to achieve the effect that the signal transceiver circuit 40 transmits Wi-Fi communication signals and cellular communication signals simultaneously.

[0079] When the signal transceiver circuit 40 transmits Wi-Fi communication signals and cellular communication signals simultaneously, the wireless transceiver module 42 can send the first Wi-Fi communication signal to the power splitter module 44 through the first transmission path 421, and the cellular transceiver module 43 can send the first cellular communication signal to the power splitter module 44 through the second transmission path 431. Correspondingly, the power splitter module 44 can obtain the first Wi-Fi communication signal through the first port 441 and obtain the first cellular communication signal through the second port 442. The power splitter module 44 can combine the first Wi-Fi communication signal and the first cellular communication signal to obtain a first combined signal, and then transmit the first combined signal to the first antenna 41. The first antenna 41 converts the first combined signal into a radiation signal and transmits it, so as to achieve the simultaneous transmission of Wi-Fi communication signals and cellular communication signals.

[0080] In some embodiments, the power splitting module 44 may include a power splitter (simply referred to as a splitter). During the simultaneous transmission of cellular communication signals and Wi-Fi communication signals, the splitter can combine the energy of the multiplexed communication signals on the first transmission path 421 and the second transmission path 431 into one output. For example, the first Wi-Fi communication signal transmitted by the wireless transceiver module 42 and the first cellular communication signal transmitted by the cellular transceiver module 43 are combined into a first combined signal and transmitted through the first antenna 41 to achieve the effect of simultaneously transmitting cellular communication signals and Wi-Fi communication signals.

[0081] 2. The signal transceiver circuit 40 simultaneously receives Wi-Fi communication signals and cellular communication signals:

[0082] The power splitting module 44 is configured to obtain a second combined signal received by the first antenna 41. The second combined signal includes a second Wi-Fi communication signal and a second cellular communication signal. The power splitting module 44 transmits a second combined signal with a first power ratio to the wireless transceiver module 42 through the first transmission path 421, and transmits a second combined signal with a second power ratio to the cellular transceiver module 43 through the second transmission path 431.

[0083] The wireless transceiver module 42 is further configured to obtain the second Wi-Fi communication signal based on the second combined signal with the first power ratio, and the cellular transceiver module 43 is further configured to obtain the second cellular communication signal based on the second combined signal with the second power ratio, so as to achieve the effect that the signal transceiver circuit 40 simultaneously receives Wi-Fi communication signals and cellular communication signals.

[0084] When the signal transceiver circuit 40 simultaneously receives Wi-Fi communication signals and cellular communication signals, the power splitting module 44 can obtain the second combined signal received by the first antenna 41, and divide the second combined signal into two communication signals through the first port 441 and the second port 442, so as to transmit a second combined signal with a first power ratio to the wireless transceiver module 42 through the first transmission path 421, and transmit a second combined signal with a second power ratio to the cellular transceiver module 43 through the second transmission path 431. Correspondingly, the wireless transceiver module 42 can obtain the second Wi-Fi communication signal from the second combined signal with the first power ratio, and the cellular transceiver module 43 can obtain the second cellular communication signal from the second combined signal with the second power ratio.

[0085] In some embodiments, during the process of simultaneously receiving cellular communication signals and Wi-Fi communication signals as described above, the power divider included in the power splitting module 44 can also split the signal energy of the communication signal (such as the second combined signal) input from the first antenna 41 and the power splitting module 44 into two outputs, such as the second combined signal with the first power ratio and the second combined signal with the second power ratio, so that the wireless transceiver module 42 and the cellular transceiver module 43 can respectively obtain a second combined signal containing the corresponding communication signal.

[0086] In some embodiments, the first power ratio and the second power ratio can be the same, so that the wireless transceiver module 42 and the cellular transceiver module 43 can obtain combined signals with the same signal energy.

[0087] In some embodiments, the first power ratio and the second power ratio can also be different. For example, in a scenario where the cellular communication signal is weak, the first power ratio can be less than the second power ratio to improve the reception success rate of the cellular communication signal by the cellular transceiver module 43. Or, in a scenario where the Wi-Fi communication signal is weak, the first power ratio is greater than the second power ratio to improve the reception success rate of the Wi-Fi communication signal by the wireless transceiver module 42.

[0088] In some embodiments, the wireless transceiver module 42 includes a wireless transceiver. When the wireless transceiver module 42 receives the second combined signal with the first power ratio, the wireless transceiver can identify and obtain the second Wi-Fi communication signal in the second combined signal with the first power ratio by means such as frequency detection, modulation method identification, and protocol feature identification.

[0089] In some embodiments, the cellular transceiver module 43 includes a cellular transceiver.

[0092] The wireless transceiver module 42 is also used to send a third Wi-Fi communication signal;

[0093] The power splitting module 44 is also used to obtain the third Wi-Fi communication signal sent by the wireless transceiver module 42 through the first transmission path 421 and transmit the third Wi-Fi communication signal through the first antenna 41, so as to achieve the effect that the signal transceiver circuit 40 only transmits Wi-Fi communication signals.

[0094] 2. The signal transceiver circuit 40 only receives Wi-Fi communication signals:

[0095] The power splitter module 44 is further configured to obtain the fourth Wi-Fi communication signal received by the first antenna 41 and send the fourth Wi-Fi communication signal to the wireless transceiver module 42 through the first transmission path 421;

[0096] The wireless transceiver module 42 is further configured to obtain the fourth Wi-Fi communication signal sent by the power splitter module 44 through the first transmission path 421, so as to achieve the effect that the signal transceiver circuit 40 only receives Wi-Fi communication signals.

[0097] When the signal transceiver circuit 40 only transmits Bluetooth communication signals, the single path corresponding to the first port 441 of the power splitter module 44 can be enabled to only conduct the path between the wireless transceiver module 42, the first port 441 of the power splitter module 44 and the first antenna 41, and receive and transmit Wi-Fi communication signals through this path.

[0098] In some embodiments, the signal transceiver circuit 40 can also only transmit cellular communication signals:

[0099] 1. The signal transceiver circuit 40 only transmits cellular communication signals:

[0100] The cellular transceiver module 43 is further configured to send the third cellular communication signal;

[0101] The power splitter module 44 is configured to obtain the third cellular communication signal sent by the wireless transceiver module 42 through the second transmission path 431 and transmit the third cellular communication signal through the first antenna 41, so as to achieve the effect that the signal transceiver circuit 40 only transmits cellular communication signals.

[0102] 2. The signal transceiver circuit 40 only receives cellular communication signals:

[0103] The power splitter module 44 is further configured to obtain the fourth cellular communication signal received by the first antenna 41 and send the fourth cellular communication signal to the wireless transceiver module 42 through the second transmission path 431;

[0104] The cellular transceiver module 43 is further configured to obtain the fourth cellular communication signal sent by the power splitter module 44 through the second transmission path 431, so as to achieve the effect that the signal transceiver circuit 40 only receives cellular communication signals.

[0105] When the signal transceiver circuit 40 only transmits Bluetooth communication signals, the single path corresponding to the second port 442 of the power splitter module 44 can be enabled to only conduct the path between the cellular transceiver module 43, the second port 442 of the power splitter module 44 and the first antenna 41, and receive and transmit cellular communication signals through this path.

[0106] In the embodiment of the present application, the power splitting module in the signal transceiver circuit can simultaneously obtain the first cellular communication signal and the first Wi-Fi communication signal through the first port and the second port, so as to transmit the first combined signal including the first cellular communication signal and the first Wi-Fi communication signal through the first antenna. Or, the power splitting module can send the second combined signal received by the first antenna to the wireless transceiver module and the cellular transceiver module through the first port and the second port respectively, with the corresponding power ratio of the second combined signal, so that the wireless transceiver module and the cellular transceiver module can respectively obtain the second cellular communication signal and the second Wi-Fi communication signal according to the second combined signal with the corresponding power ratio. That is, through the power splitting module in the signal transceiver circuit, the simultaneous transmission or reception of the cellular communication signal and the Wi-Fi communication signal can be realized, which improves the flexibility of the communication signal transmission. And by using the power splitting module, it can be realized that when the cellular communication signal and the Wi-Fi communication signal share the same antenna, the mutual crosstalk between the cellular communication signal and the Wi-Fi communication signal can be avoided, the cost can be reduced, and the requirement for the hardware space can be reduced.

[0107] Figure 5 It is a schematic diagram of a signal transceiver circuit 50 provided by an embodiment of the present application. As Figure 5 shown, the wireless transceiver module 42 is also connected to the first antenna 41, and a third transmission path 521 is formed between the wireless transceiver module 42 and the first antenna 41, where:

[0108] The wireless transceiver module 42 is configured to send the first Wi-Fi communication signal to the power splitting module 44 through the first transmission path 421 in the first communication scenario, or is configured to send the third Wi-Fi communication signal through the third transmission path 521 in the second communication scenario, so as to transmit the third Wi-Fi communication signal through the first antenna 41.

[0109] The first communication scenario is a scenario where the signal transceiver circuit 50 simultaneously transmits the Wi-Fi communication signal and the cellular communication signal. That is, in the first communication scenario, the signal transceiver circuit 50 can simultaneously transmit the Wi-Fi communication signal and the cellular communication signal through the first transmission path 421. For specific details, refer to the description of the above embodiment. To avoid repetition, it will not be elaborated here.

[0110] In the above first communication scenario, the third transmission path 521 is in a disconnected state to avoid the situation where only the Wi-Fi communication signal can be transmitted when the third transmission path 521 is conducting, resulting in the inability to meet the signal transmission requirements of the first communication scenario.

[0111] The second communication scenario is a scenario where the signal transceiver circuit 50 only transmits Wi-Fi communication signals, that is, the signal transceiver circuit 50 can transmit Wi-Fi communication signals or receive Wi-Fi communication signals in the second communication scenario.

[0112] 1. The signal transceiver circuit 50 only transmits Wi-Fi communication signals:

[0113] The wireless transceiver module 42 is further configured to send a third Wi-Fi communication signal through the third transmission path 521, so as to transmit the third Wi-Fi communication signal through the first antenna 41, achieving the effect of only transmitting Wi-Fi communication signals.

[0114] When the signal transceiver circuit 50 only transmits Wi-Fi communication signals, the above-mentioned first transmission path 421 is in a disconnected state, so as to avoid the problem of excessive insertion loss and deteriorated performance caused by the single-path operation of the power splitter module 44 during the process of only transmitting Wi-Fi communication signals through the first transmission path 421.

[0115] 2. The signal transceiver circuit 50 only receives Wi-Fi communication signals:

[0116] The wireless transceiver module 42 is further configured to obtain a fourth Wi-Fi communication signal received by the first antenna 41 through the third transmission path 521, so as to receive the fourth Wi-Fi communication signal, achieving the effect of only receiving Wi-Fi communication signals.

[0117] When the signal transceiver circuit 50 only receives Wi-Fi communication signals, the above-mentioned first transmission path 421 is in a disconnected state, so as to avoid the problem of excessive insertion loss and deteriorated performance caused by the single-path operation of the power splitter module 44 during the process of only receiving Wi-Fi communication signals through the first transmission path 421.

[0118] In some embodiments, the signal transceiver circuit 50 can also only transmit cellular communication signals through the second transmission path 431. For specific details, refer to the description of the above embodiments. To avoid repetition, it will not be elaborated here.

[0119] When the signal transceiver circuit 50 only transmits cellular communication signals, the above-mentioned third transmission path 521 is in a disconnected state, so as to avoid the situation where the signal transceiver circuit 50 may not be able to achieve only the transmission of cellular communication signals due to the Wi-Fi communication signal preempting the first antenna 41 when the third transmission path 521 is conducting.

[0120] In the embodiments of the present application, in addition to being able to simultaneously receive Wi-Fi communication signals and cellular communication signals through the first transmission path and the second transmission path in the first communication scenario, the signal transceiver circuit can also, in the second communication scenario, achieve the transmission effect of only the third Wi-Fi communication signal through the third transmission path formed between the wireless transceiver module and the first antenna. That is, the transmission effect of only the Wi-Fi communication signal can be directly achieved through the transmission path between the wireless transceiver module and the first antenna, avoiding the problem of excessive insertion loss and resulting performance deterioration during the process of achieving only the transmission of the Wi-Fi communication signal through the single-path operation of the power splitter module.

[0121] In some embodiments, the signal transceiver circuit may further include a first switch unit, and the first switch unit is disposed on the first transmission path and the third transmission path.

[0122] In the first communication scenario, the first switch unit is in the first conduction state, so that the first transmission path is in the conduction state and the third transmission path is in the disconnected state. That is, the signal transceiver circuit can simultaneously transmit cellular communication signals and Wi-Fi communication signals through the first transmission path and the second transmission path.

[0123] In the second communication scenario, the first switch unit is in the second conduction state, so that the first transmission path is in the disconnected state and the third transmission path is in the conduction state. That is, the signal transceiver circuit can achieve the effect of only transmitting the Wi-Fi communication signal through the third transmission path. For specific details, see the following description of Figure 6 of.

[0124] Figure 6 is a schematic diagram of a signal transceiver circuit 60 provided by an embodiment of the present application. As Figure 6 shown, the first switch unit includes a first switch 623 and a second switch 611. The first switch 623 is respectively connected to the wireless transceiver module 42, the first port of the power splitter module 44, and the second switch 611. The second switch 611 is further connected to the third port 644 of the power splitter module 44 and the first antenna 41, where:

[0125] In the first communication scenario, the first switch 623 conducts the first transmission path 421, and the second switch 611 conducts the path between the third port 644 of the power splitter module 44 and the first antenna 41 to achieve the effect of the signal transceiver circuit 60 simultaneously transmitting Wi-Fi communication signals and cellular communication signals.

[0126] 1. In the first communication scenario, the signal transceiver circuit 60 simultaneously transmits Wi-Fi communication signals and cellular communication signals:

[0127] The wireless transceiver module 42 is used to transmit the first Wi-Fi communication signal through the first transmission path 421 when the first switch 623 conducts the first transmission path 421;

[0128] The cellular transceiver module 43 is used to transmit the first cellular communication signal through the second transmission path 431 when the second transmission path 431 is in a conducting state;

[0129] The power splitting module 44 is used to obtain the first Wi-Fi communication signal sent by the wireless transceiver module 42 through the first transmission path 421 when the first switch 623 conducts the first transmission path 421, and obtain the first cellular communication signal sent by the cellular transceiver module 43 through the second transmission path 431 when the second transmission path 431 is in a conducting state, combine the first Wi-Fi communication signal and the first cellular communication signal to obtain a first combined signal, and transmit the first combined signal through the first antenna 41 when the second switch 611 conducts the path between the third port 644 of the power splitting module 44 and the first antenna 41, so as to achieve the effect that the signal transceiver circuit 60 simultaneously transmits Wi-Fi communication signals and cellular communication signals.

[0130] As Figure 6 shown, when the signal transceiver circuit 60 simultaneously transmits Wi-Fi communication signals and cellular communication signals, the third transmission path 521 between the wireless transceiver module 42 and the second switch 611 can also be made in a disconnected state through the first switch 623, and the third transmission path between the first switch 623 and the first antenna 41 can be made in a disconnected state through the second switch 611, so as to avoid the problem that the signal transceiver circuit 60 can only transmit Wi-Fi communication signals due to the transmission of Wi-Fi communication signals through the third transmission path 521.

[0131] 2. In the first communication scenario, the signal transceiver circuit 60 simultaneously receives Wi-Fi communication signals and cellular communication signals:

[0133] The wireless transceiver module 42 is further configured to obtain a second Wi-Fi communication signal according to the second combined signal of the first power ratio, and the cellular transceiver module 43 is further configured to obtain the second cellular communication signal according to the second combined signal of the second power ratio, so as to achieve the effect that the signal transceiver circuit 60 can receive the Wi-Fi communication signal and the cellular communication signal simultaneously.

[0134] As Figure 6 shown, when the signal transceiver circuit 60 receives the Wi-Fi communication signal and the cellular communication signal simultaneously, the third transmission path 521 between the wireless transceiver module 42 and the second switch 611 can also be disconnected through the first switch 623, and the third transmission path between the first switch 623 and the first antenna 41 can be disconnected through the second switch 611, so as to avoid receiving the Wi-Fi communication signal through the third transmission path 521, which may cause the problem that the signal transceiver circuit 60 can only receive the Wi-Fi communication signal.

[0135] In the second communication scenario, the first switch 623 conducts the path between the wireless transceiver module 42 and the second switch 611, and the second switch 611 conducts the path between the first switch 623 and the first antenna 41. The second communication scenario is the scenario where the signal transceiver circuit 60 only transmits the Wi-Fi communication signal, that is, the signal transceiver circuit 60 can transmit or receive the Wi-Fi communication signal in the second communication scenario.

[0140] The wireless transceiver module 42 is further configured to, when the first switch 623 conducts the path between the wireless transceiver module 42 and the second switch 611, and the second switch 611 conducts the path between the first switch 623 and the first antenna 41, obtain the third Wi-Fi communication signal received by the first antenna 41 through the third transmission path 521, so as to receive the third Wi-Fi communication signal, achieving the effect that the signal transceiver circuit only receives Wi-Fi communication signals.

[0141] As Figure 6 shown, when the signal transceiver circuit 60 only receives Wi-Fi communication signals, the first transmission path 421 between the wireless transceiver module 42 and the power splitter module 44 can also be made in a disconnected state through the first switch 623, and the first transmission path 421 between the power splitter module 44 and the first antenna 41 can be made in a disconnected state through the second switch 611, so as to avoid the problem of excessive insertion loss and deteriorated performance due to the single-path operation of the power splitter module 44 on this path during the process of only receiving Wi-Fi communication signals through the first transmission path 421.

[0149] In the embodiment of the present application, the signal transceiver circuit further includes a first switch unit. The first switch unit is disposed on the first transmission path and the third transmission path. The signal transceiver circuit can control the conducting state of the first switch unit in different communication scenarios, so that the first transmission path and the third transmission path are in corresponding conducting states, so as to simultaneously transmit Wi-Fi communication signals and cellular communication signals through the first transmission path and the second transmission path with a power splitter module in the first communication scenario, and only transmit Wi-Fi communication signals through the third transmission path without a power splitter module in the second communication scenario, so as to avoid the problem of performance deterioration due to excessive insertion loss caused by the single-path operation of the power splitter module during the process of only transmitting Wi-Fi communication signals through the first transmission path with a power splitter module.

As Figure 8 shown, the second switch unit may include a third switch 833 and a fourth switch 812. The third switch 833 is respectively connected to the cellular transceiver module 43, the second port 442 of the power splitter module 44, and the fourth switch 812. The fourth switch 812 is also connected to the third port 644 of the power splitter module 44 and the first antenna 41, where:

[0164] In the first communication scenario, the third switch 833 turns on the second transmission path 431, and the fourth switch 812 turns on the path between the third port 644 of the power splitter module 44 and the first antenna 41, so as to achieve the effect that the signal transceiver circuit 80 simultaneously transmits Wi-Fi communication signals and cellular communication signals.
