Wherein, the switch 1 is a double-pole four-throw switch, and the switch 2 and the switch 3 are single-pole double-throw switches.
Thus, in the working scenario of simultaneous transmission of N41 and 2.4G, taking the transmission signal N41 at the signal transmission port 1 of the second transceiver and the transmission signal 2.4G at the signal transmission port 1 of the first transceiver as an example, the transmission signal flow of N41 is as follows: a signal transmitting port 1 of the second transceiver is input to the duplexer 1 through a first end of the duplexer 1, then output to a first end of the power amplifying unit 1 through a second end of the duplexer 1, and output to a first end of the switch 1 through a fourth end of the power amplifying unit 1; the 2.4G emission signal flow direction is as follows: the signal transmitting port 1 of the first transceiver is input to the duplexer 1 through the third end of the duplexer 1, then output to the first end of the power amplifying unit 1 through the second end of the duplexer 1, and output to the first end of the switch 1 through the fourth end of the power amplifying unit 1. The paths output to the first end of the power amplification unit 1 through the second end of the duplexer 1 and then output to the first end of the switch 1 through the fourth end of the power amplification unit 1 are N41 and 2.4G multiplexing paths.
In the working scenario of simultaneous reception of N41 and 2.4G, taking the received signal of the antenna 3 as an example, the received signal of the antenna 3 is conducted to the low noise amplifier 3 through the switch 2, and the first end of the low noise amplifier 3 is output to the second end of the duplexer 5, where the N41 received signal is output from the first end of the duplexer 5 to the signal receiving port 3 of the second transceiver; the 2.4G receiving signal is output from the third terminal of the duplexer 5 to the signal receiving port 1 of the first transceiver. Similarly, the received signal of the antenna 4 is similar to the received signal of the antenna 3, and the signal reception of the signal receiving port 4 of the second transceiver and the signal reception of the signal receiving port 2 of the first transceiver are realized. Among the received signals of the antenna 1 and the antenna 2, the received signal corresponding to the signal receiving port 1 of the second transceiver is output to the fourth end of the power amplifying unit 1 through the first end of the switch 1, then output to the second end of the duplexer 2 through the third end of the power amplifying unit 1, and output to the second end of the low noise amplifier 1 through the third end of the duplexer 2, and further output to the signal receiving port 1 of the second transceiver through the first end of the low noise amplifier 1. Similarly, a received signal corresponding to the signal receiving port 2 of the second transceiver is output to the fourth terminal of the power amplifying unit 2 through the second terminal of the switch 1, then output to the second terminal of the duplexer 4 through the third terminal of the power amplifying unit 2, and output to the second terminal of the low noise amplifier 3 through the third terminal of the duplexer 4, and further output to the signal receiving port 2 of the second transceiver through the first terminal of the low noise amplifier 2.
In the working scenario of N41 transmission and 2.4G reception, since the 2.4G reception uses the N41 MIMO channel, there is no multiplexing channel in this scenario.
In the working scenario of N41 receiving and 2.4G transmitting, the flow direction of the N41 receiving signal is not repeated here, but the flow direction of the 2.4G transmitting signal, taking the transmitting signal of the signal transmitting port 1 of the first transceiver as an example, is input to the duplexer 1 through the third terminal of the duplexer 1, then output to the first terminal of the power amplifying unit 1 through the second terminal of the duplexer 1, then output to the second terminal of the duplexer 2 through the third terminal of the power amplifying unit 1, output to the second terminal of the power amplifying unit 1 through the first terminal of the duplexer 2, and finally output to the first terminal of the switch 1 through the fourth terminal of the power amplifying unit 1. Likewise, the transmission signal of the signal transmission port 2 of the first transceiver is similar to the transmission signal of the signal transmission port 1. The radio frequency switch in the power amplification unit cuts a single-pole double-throw signal to the duplexer, the duplexer divides an N41 received signal to be sent to the connected low-noise amplifier, the 2.4G end of the duplexer is connected with the other switch in the power amplification unit, and the switch is connected with the internal 2.4G amplifier to realize the amplification of the 2.4G transmitting signal.
Thus, a 2.4G receive multiplexed N41 multiple-input multiple-output MIMO path, and a 2.4G transmit multiplexed N41 transmit signal TX path. The 2.4G and N41 duplexers are arranged at the rear end of the low-noise amplifier of the shared receiving signal path, the quality of a received signal is ensured while the low-noise amplifier is multiplexed, and the parallel operation of 2.4G receiving and N41 transmitting or receiving can be ensured at the moment. The shared transmitting signal path needs to ensure that the N41 and the 2.4G transmit-receive work in parallel, two 2.4G and N41 duplexers are respectively added, and simultaneously, an internal radio frequency switch of the power amplifier needs to be multiplexed when the N41 receives.
In this embodiment, the first power amplifying unit may further support an envelope tracking technique ET, and acquire, through a differential signal line, envelope information of a transmission signal output by the 2.4G modem, that is, the ET may be implemented during 2.4G transmission, and dynamically adjust a power supply voltage of the power amplification PA according to the envelope information, thereby reducing power consumption of 2.4G transmission.

For example, as shown in fig. 3, a first transceiver connected to a first modem is for 2.4G signals, and has 2 signal transmitting terminals and 2 signal receiving terminals; the second transceiver, which is connected to the second modem, is for the signal of B41, and has 1 signal transmitting end and 4 signal receiving ends. Wherein the power amplifying unit 1 is a second power amplifying unit, the low noise amplifier 1 is a third low noise amplifier, the low noise amplifier 2 is a fourth low noise amplifier, the low noise amplifier 3 and the low noise amplifier 4 are fifth low noise amplifiers, the duplexer 1 and the duplexer 2 are a third duplexer, the switch 1 is a first switch, and the switch 2 and the switch 3 are second switches.
Specifically, a first end of a power amplification unit 1 is connected with a signal transmitting terminal 1 of a second transceiver, a second end of the power amplification unit 1 is connected with a second end of a low noise amplifier 1, a third end of the power amplification unit 1 is connected with a first end of a switch 1, a second end of the switch 1 is connected with a second end of a low noise amplifier 2, a first end of the low noise amplifier 1 is connected with a signal receiving terminal 1 of the second transceiver, a first end of the low noise amplifier 2 is connected with a signal receiving terminal 2 of the second transceiver, a first end of a duplexer 1 is connected with a signal receiving terminal 3 of the second transceiver, a second end of the duplexer 1 is connected with a first end of the low noise amplifier 3, a third end of the duplexer 1 is connected with the signal receiving terminal 1 of the first transceiver, a second end of the low noise amplifier 3 is connected with a first end of the switch 2, a second end of the switch 2 is connected with the signal transmitting terminal 1 of the first transceiver, the third terminal of the switch 2 is connected to the antenna 3. Similarly, the first end of the duplexer 2 is connected to the signal receiving end 4 of the second transceiver, the second end of the duplexer 2 is connected to the first end of the low noise amplifier 4, the third end of the duplexer 2 is connected to the signal receiving end 2 of the first transceiver, the second end of the low noise amplifier 4 is connected to the first end of the switch 3, the second end of the switch 3 is connected to the signal transmitting end 2 of the first transceiver, and the third end of the switch 3 is connected to the antenna 4. The third end of the switch 1 is connected with the antenna 1, and the fourth end is connected with the antenna 2. Wherein, the switch 1 is a double-pole double-throw switch, and the switch 2 and the switch 3 are single-pole double-throw switches.
Thus, in the single B42 operational scenario, the received signal flows as follows: among the received signals of the antenna 1 and the antenna 2, the received signal corresponding to the signal receiving port 1 of the second transceiver is output to the third end of the power amplifying unit 1 through the first end of the switch 1, then is output to the second end of the low noise amplifier 1 through the second end of the power amplifying unit 1, and then is output to the signal receiving port 1 of the second transceiver through the first end of the low noise amplifier 1; the received signal corresponding to the signal receiving port 2 of the second transceiver is output to the second end of the low noise amplifier 2 through the second end of the switch 1, and then output to the signal receiving port 2 of the second transceiver through the first end of the low noise amplifier 2. The received signal of the antenna 3 is conducted to the low noise amplifier 3 through the switch 2, the first end of the low noise amplifier 3 is output to the second end of the duplexer 1, and then the first end of the duplexer 1 is output to the signal receiving end 3 of the second transceiver. Similarly, the received signal of the antenna 4 is conducted to the low noise amplifier 4 through the switch 3, and the first end of the low noise amplifier 4 is output to the second end of the duplexer 2, and then output to the signal receiving end 4 of the second transceiver through the first end of the duplexer 2.
In an individual WIFI 2.4G working scene, the received signal flow is as follows: the receiving signal of the antenna 3 is conducted to the low noise amplifier 3 through the switch 2, the first end of the low noise amplifier 3 is output to the second end of the duplexer 1, and then is output to the signal receiving end 1 of the first transceiver through the third end of the duplexer 1. Similarly, the received signal of the antenna 4 is conducted to the low noise amplifier 4 through the switch 3, and the first end of the low noise amplifier 4 is output to the second end of the duplexer 2, and then is output to the signal receiving end 2 of the first transceiver through the third end of the duplexer 2.
It can be known that, in the connection manner shown in fig. 3, B41 transmission and WIFI 2.4G transmission can be performed simultaneously; b41 transmission and WIFI 2.4G reception may be performed simultaneously; b414 x4 MIMO reception and WIFI 2.4G reception may be performed simultaneously; b412 x2MIMO reception and WIFI 2.4G transmission may be performed simultaneously. Since the two MIMO channels of 2.4G transmission and B41 are multiplexed by the single-pole double-throw switch, when 2.4G is in the transmission state, the two MIMO channels of B41 cannot operate, and at this time, B41 can only operate in the 2x2MIMO mode. However, since 2.4G and B41 are both in TDD mode, i.e. neither 2.4G nor B41 needs to maintain the transmitting or receiving state continuously, the second switch can be controlled according to the data traffic situation of 2.4G and B41, for example, when the downlink traffic data volume of B41 is large, the duty cycle of the single-pole double-throw switch to B41 is increased, and the influence of B41 receiving MIMO channel occupied by 2.4G transmission is reduced by increasing the duty cycle of high-priority traffic.
Thus, 2.4G and LTE B41 multiplex the same low noise amplifier received signal, place 2.4G and B41 duplexer at the low noise amplifier rear end, guarantee received signal quality while multiplexing low noise amplifier.
