As shown in fig. 2, in one embodiment, the processing circuit 10 is configured with a first output port WIFI TX0 for providing a first radio frequency signal, a second output port WIFI TX1, a third output port BT TRX for providing a second radio frequency signal, a first input port WIFI RX0 for receiving the first radio frequency signal, a second input port WIFI RX1, and a third input port BT RX for receiving the second radio frequency signal.

Specifically, each transceiver circuit includes a transceiver module and a filter module. Illustratively, the first transceiver circuit may include a first transceiver module 210 and a first filter module 220; the second transceiver circuit may include a second transceiver module 310 and a second filter module 320; the third transceiver circuit may include a third transceiver module 410 and a third filter module 420. Wherein, the first transceiver module 210 and the second transceiver module 310 are both capable of supporting the receiving and transmitting processes of the first radio frequency signal; the third transceiver module 410 is capable of supporting both receive and transmit processing of the second radio frequency signal. The first/second/third transceiver modules 410, 420, 430 may include a power amplifier, a low noise amplifier, a radio frequency switch, and a coupler, respectively. The power amplifier is configured to perform power amplification processing on the radio frequency signal output by the processing circuit 10 to increase the target transmission power and increase the transmission distance, and the low noise amplifier is configured to perform low noise amplification processing on the radio frequency signal received by the antenna to increase the receiving sensitivity and increase the receiving distance. The radio frequency switch can be respectively connected with the power amplifier, the low noise amplifier and the filtering module and is used for selecting and conducting radio frequency paths between the power amplifier, the low noise amplifier and the filtering module. That is, the cut flower switch may be used to select switching between transmission and reception of the first radio frequency signal. The coupler is disposed on the rf path between the power amplifier and the rf switch, and is configured to couple and feedback a target transmit power of a portion of the rf signal to the processing circuit 10, so as to implement power detection of the rf signal.

The first/second/third filtering modules 410, 420, 430 may be 2.4G filters, and are configured to Filter unwanted signals outside the 2.4GHz band, so as to implement filtering processing for the first radio frequency signal and the second radio frequency signal. It should be noted that, in the embodiment of the present application, the first radio frequency signal (for example, WIFI 2.4G frequency band) and the second radio frequency signal (for example, bluetooth signal) are both operating in the 2.4G-2.8G frequency band, and the first/second/third filtering module 420 may use the same filter to achieve the effect of filtering unwanted signals outside the 2.4GHz frequency band.

As shown in fig. 3, the first transceiver circuit 20 is exemplified for convenience of explanation. Specifically, the first transceiver circuit 20 includes a first power amplifier 211, a first low noise amplifier 212, a first coupler 213, a first radio frequency switch 214, and a first filtering module 220. The input end of the first power amplifier 211 is connected to a first output port WIFI TX0, the output end of the first power amplifier 211 is connected to a first end of the first radio frequency switch 214 through a first coupler 213, the second end of the first radio frequency switch 214 is connected to the first antenna ANT0 through a first filter module 220, the input end of the first low noise amplifier 212 is connected to another first end of the first radio frequency switch 214, and the output end of the first low noise amplifier 212 is connected to the first input port WIFI RX 0.

The first power amplifier 211 receives a first radio frequency signal output by the first output port WIFI TX0, performs power amplification processing on the first radio frequency signal, transmits the first radio frequency signal after the power amplification processing to the first coupler 213, transmits the first radio frequency signal to the first radio frequency switch 214 through the first coupler 213, switches to the first filter module 220 through the first radio frequency switch 214, and outputs the first radio frequency signal to the first antenna ANT0 after the filter processing of the first filter module 220, so as to implement transmission processing on the first radio frequency signal.

The first radio frequency signal received by the first antenna ANT0 is transmitted to the first filtering module 220, and is output to the first radio frequency switch 214 after being filtered by the first filtering module 220, and is switched to the first low noise amplifier 212 by the first radio frequency switch 214, and the first low noise amplifier 212 performs low noise amplification processing on the received first radio frequency signal and then outputs the first radio frequency signal to the first input port WIFI RX0, so as to implement receiving processing on the first radio frequency signal.

As shown in fig. 4, in one embodiment, the transceiver modules in each transceiver circuit further include a bypass switch, for example, the first transceiver module 210 includes a first bypass switch 215, the second transceiver module 310 includes a second bypass switch 315, and the third transceiver module 410 includes a third bypass switch 415. The first end of the bypass switch is connected with the input end of the low noise amplifier, and the second end of the bypass switch is connected with the output end of the low noise amplifier. When the power of the radio frequency signal received by the antenna is overlarge, the bypass switch is turned on, the radio frequency signal can be directly transmitted to the processing circuit 10 through the bypass switch and can not be amplified by the low noise amplifier, so that the condition that the low noise amplifier works in a saturated state due to overlarge power of the received radio frequency signal can be avoided, the receiving performance is influenced, and meanwhile, the low noise amplifier can be protected.

In one embodiment, the processing circuit 10 is further configured to: and respectively acquiring the isolation degree of the first antenna ANT0 and the third antenna ANT2 and the target transmitting power of the first radio frequency signal, and determining the interference information of the first radio frequency signal on the second radio frequency signal according to the isolation degree and the target transmitting power.

The processing circuit 10 in the radio frequency system may collect WIFI information such as WIFI format, channel, bandwidth, rate and the like negotiated by the radio frequency system and the router. And the target transmitting power is matched with the current WIFI information based on the collected WIFI information and a preset mapping relation. The preset mapping relation is used for representing the corresponding relation between the WIFI information and the target transmitting power. Illustratively, the higher the rate, the lower the target transmit power configured; the larger the bandwidth, the lower the target transmit power configured. The preset mapping relationship may be stored in the processing circuit 10 in the form of a table.

The processing circuit 10 is further configured to obtain interference information according to the target transmission power of the WIFI signal and the isolation between the two antennas. The isolation between the two antennas can be understood as the isolation between the WIFI antenna and the bluetooth antenna. The WIFI antenna may be the first antenna ANT0 connected to the first transceiver circuit 20, or may be the first antenna ANT0 connected to the first transceiver circuit 20. The bluetooth antenna may be a third antenna ANT2 connected to the third transceiving circuit 40.

Further, the interference information may include an interference strength value P [ wifi_in_bt ], where the interference strength value P [ wifi_in_bt ] is a difference between a target transmit power of the WIFI signal and an antenna isolation. Specifically, the interference strength value P [ wifi_in_bt ] may be understood as the strength of an interference signal where the transmission signal of the WIFI signal falls within the bluetooth information operating bandwidth.

It should be noted that, the target transmitting power of the two WIFI transceiver paths may be the same or different. When the processing circuit 10 acquires the interference signal, it can screen out the larger target transmitting power in the two WIFI receiving and transmitting paths, and take the difference between the larger target transmitting power and the antenna isolation as the aforementioned interference information.

Based on the radio frequency system as shown in fig. 4, the processing circuit 10 is further configured to: when the interference information is smaller than the first threshold, the processing circuit 10 controls the first transceiver circuit 20, the second transceiver circuit 30 and the third transceiver circuit 40 to operate simultaneously.

When the interference information (for example, P [ wifi_in_bt ]) is less than the first preset threshold, it is indicated that the interference of the WIFI signal to the bluetooth signal is less, and bluetooth communication and WIFI communication can be supported to be performed simultaneously. The processing circuit 10 controls the first target transceiver circuit and the third transceiver circuit 40 to operate independently of each other in a frequency division multiplexing mode. The first target transceiver circuit includes the first transceiver circuit 20 and the second transceiver circuit 30. Specifically, the processing circuit 10 may control the first output port WIFI TX0 and the second output port WIFI TX1 to output WIFI signals to the corresponding first transceiver circuit 20 and the second transceiver circuit 30, respectively, so as to implement processing of the WIFI signals in a MIMO state; meanwhile, the processing circuit 10 may control the third output port BT TRX to output a bluetooth signal to the corresponding third transceiver circuit 40, so as to implement that bluetooth communication and WIFI communication work independently of each other in a frequency division multiplexing mode.

In this embodiment, the first target transceiver circuit and the third transceiver circuit 40 operate independently of each other in a frequency division multiplexing mode, and the bluetooth communication and the WIFI communication do not affect each other, and any performance of the two is not sacrificed. In addition, by setting the independent third antenna ANT2 (bluetooth antenna), the flexibility of the antenna layout can be improved, and the isolation between the WIFI antenna and the bluetooth antenna can be improved.

Based on the radio frequency system as shown IN fig. 4, IN one embodiment, when the first preset threshold < the interference information (e.g., P [ wifi_in_bt ]) is < the second preset threshold, it is indicated that the WIFI transceiving path configured IN the second target transceiving circuit has less influence on the bluetooth transceiving path configured IN the third transceiving circuit 40; and the WIFI transceiving path configured in one transceiving circuit other than the target transceiving circuit has a greater influence on the bluetooth transceiving path configured in the third transceiving circuit 40. The second target transceiver circuit may be one of the first transceiver circuit 20 and the second transceiver circuit 30. The second target transceiver circuit is the transceiver circuit closest to the third transceiver circuit 40. For example, if the first transceiver circuit 20 is the second target transceiver circuit, the WIFI transceiver path configured in the second transceiver circuit 30 has a larger influence on the transceiver path configured in the third transceiver circuit 40. In this scenario, the processing circuit 10 is further configured to control the second target transceiver circuit and the third transceiver circuit 40 to operate independently of each other in a frequency division multiplexing mode of operation.

Specifically, the processing circuit 10 may control the target Output port to Output the WIFI signal to the corresponding second target transceiver circuit, and implement processing of the WIFI signal in a Single-Input Single-Output (SISO) state; meanwhile, the processing circuit 10 may control the third output port BT TRX to output a bluetooth signal to the corresponding third transceiver circuit 40, so as to implement that bluetooth communication and WIFI communication work independently of each other in a frequency division multiplexing mode.

In this embodiment, the processing circuit 10 may control the second target transceiver circuit and the third transceiver circuit 40 to operate independently of each other in the frequency division multiplexing mode, so that uninterrupted operation of WIFI communication and bluetooth communication may be ensured, and thus low latency characteristics of the two may be ensured.

Based on the rf system shown in fig. 4, in one embodiment, when the interference information is greater than the second threshold, it is indicated that the first transceiver circuit 20 and the second transceiver circuit 30 have a larger interference effect on the third transceiver circuit 40, respectively, so that the processing circuit 10 controls the first target transceiver circuit and the third transceiver circuit 40 to operate independently of each other in a time division multiplexing mode, that is, bluetooth communication and WIFI communication may be performed in a time division manner. Specifically, the processing circuit 10 may control the first output port WIFI TX0 and the second output port WIFI TX1 to output WIFI signals to the corresponding first transceiver circuit 20 and second transceiver circuit 30 respectively in the first period, so as to implement processing of the WIFI signals in a MIMO state; the processing circuit 10 may control the third output port BT TRX to output the bluetooth signal to the corresponding third transceiver circuit 40 during the second period of time, so as to implement that the bluetooth communication and the WIFI communication operate independently of each other in the frequency division multiplexing mode.

In this embodiment, the first target transceiver circuit and the third transceiver circuit 40 operate in a time division multiplexing mode, so that mutual interference between the WIFI signal and the bluetooth signal is completely avoided.

In one embodiment, the first transceiver circuit 20 is further configured to support a process of receiving and transmitting the second radio frequency signal. That is, the first transceiver circuit 20 may support the transceiving processing of the first radio frequency signal and the second radio frequency signal. The two first ends of the switch circuit are respectively connected with the first output port WIFI TX0 and the third output port BT TRX in a one-to-one correspondence manner, and the two second ends of the switch circuit are respectively connected with the first transceiver circuit 20 and the third transceiver circuit 40 in a one-to-one correspondence manner. Wherein the processing circuit 10 is further configured to: the on state of the switch circuit is controlled to selectively conduct the radio frequency paths between the third output port BT TRX and the first transceiver circuit 20 and the third transceiver circuit 40, respectively, and to selectively conduct the radio frequency paths between the first output port WIFI TX0 and the first transceiver circuit.

In the embodiment of the present application, the first transceiver circuit 20 may be used as a WIFI transceiver path or a bluetooth transceiver path, the second transceiver circuit 30 may be used as an independent WIFI transceiver path, and the third transceiver circuit 40 may be used as an independent bluetooth transceiver path, so that the capability of independently working with bluetooth communication and WIFI paths is provided; meanwhile, by controlling the switch circuit, the switching of the bluetooth signal between the first transceiving path and the third transceiving circuit 40 can be realized, so that the radio frequency system can support a plurality of coexistence modes, and the coexistence requirements of the radio frequency system in a plurality of different complex environments, the WIFI communication and the bluetooth communication can be met.

As shown in fig. 5, in one embodiment, the switching circuit includes a first switching unit 510 and a second switching unit 520. The first switch unit 510 is connected to the first output port WIFI TX0, the second switch unit 520, and the first transceiver circuit 20, and the second switch unit 520 is connected to the third output port BT TRX, the first switch unit 510, and the second transceiver circuit 30, respectively; the first switching unit 510 is configured to turn on or off a radio frequency path for transmitting the first short-range wireless communication signal to the first transceiver circuit 20, and turn on or off a radio frequency path for transmitting the second short-range wireless signal to the first transceiver circuit 20; the second switch unit 520 is configured to selectively turn on the rf path of the third output port BT TRX and the first transceiver circuit 20 or the third transceiver circuit 40, respectively.

In the embodiment of the present application, for convenience of explanation, the first switch unit 510 and the second switch unit 520 each include a single pole double throw switch. Wherein the first switching unit 510 includes a first SPDT switch, and the second switching unit 520 includes a second SPDT switch. Specifically, two first ends of the first SPDT switch are respectively connected to the first output port WIFI TX0 and a second end of the second SPDT switch, and the second end of the first SPDT switch is connected to the input end of the first power amplifier 211. A first end of the second SPDT switch is connected to the third output port BT TRX, and the other second end of the second SPDT switch is connected to the power amplifier in the third transceiver circuit 40. Wherein the processing circuit 10 may control the first switching unit 510 and the second switching unit 520 to selectively turn on the first transmission path and the third transmission path of the bluetooth signal output by the third output port BT TRX.

By switching the first switching unit 510 and the second switching unit 520, the bluetooth signal may be selected to continue to operate on the third transceiver circuit 40 or to switch to operate on the first transceiver circuit 20. Specifically, when the first switch unit 510 turns on the path between the second switch unit 520 and the first power amplifier 211 and turns off the path between the first output port WIFI TX0 and the first power amplifier 211 under the control of the radio frequency circuit, in addition, the second switch unit 520 may turn on the path between the third output port BT TRX and the first power amplifier 211 and turn off the path between the third output port BT TRX and the third power amplifier under the control of the processing circuit 10, the first transceiver circuit 20 may support the transceiver processing of the second radio frequency signal.

Based on the radio frequency system as shown in fig. 5, the processing circuit 10 is further configured to: when the interference information is smaller than a first threshold, the processing circuit 10 controls the on state of the switch circuit to make the first target transceiver circuit and the third transceiver circuit 40 operate independently of each other in a frequency division multiplexing operation mode, wherein the first target transceiver circuit includes the first transceiver circuit 20 and the second transceiver circuit 30 for supporting the transceiver processing of the first radio frequency signal.
