First embodiment

In this embodiment, fig. 2 shows a schematic structural diagram of a communication terminal, which has the problems that the area of a PCB board used is large and the cost of the communication terminal is high. The reason for this problem is that: the first power amplifier module adopts a first power supply circuit to supply power, the second power amplifier module adopts a second power supply circuit to supply power, and when the first power amplifier module processes 4G signals with the frequency band number of B1, for example, and when the second power amplifier module processes 5G signals with the frequency band number of N1, the frequency ranges actually processed by the first power amplifier module and the second power amplifier module are consistent. That is, the first power amplifier module and the second power amplifier module are identical in function, and the communication terminal of the related art is provided with the first power amplifier module and the second power amplifier module which have the same function, so that the cost is increased. And, first power amplifier module and second power amplifier module set up on the PCB board, set up the unanimous first power amplifier module of function and second power amplifier module simultaneously on the PCB board, can make the area of the PCB who occupies big.

Optionally, the communication terminal shown in fig. 2 further includes two filters, one filter is disposed between the radio frequency switch and the first power amplifier module, and the other filter is disposed between the radio frequency switch and the second power amplifier module. However, when the first power amplifier module processes, for example, a 4G signal with a band number of B1, and the second power amplifier module processes, for example, a 5G signal with a band number of N1, the functions of the two filters are the same, and the two filters with the same function are provided, which increases the cost of the communication terminal.

In view of the foregoing technical problems, an embodiment of the present application provides a communication terminal, where a switch is disposed between a power supply module and a first power amplifier, and a first link and a second link are disposed between a point source and the first power amplifier. The processor receives and identifies the network signal from the transceiver and generates first control information and second control information according to the type network signal; the first control information may be distributed to a switch that switches the first power amplifier into the first link or the second link according to the first control information. And the second control information is distributed to the power supply module, and the power supply module supplies power to the first link or the second link respectively according to the second control information so that the first power amplifier amplifies the network signal.

By the arrangement, the first power amplifier can be switched into different signal amplification links through the selector switch, and network signals corresponding to the first power amplifier module and the second power amplifier module can be processed; that is, only the first power amplifier is disposed on the PCB in the communication terminal in the embodiment of the present application, so that different network signals can be amplified, the number of corresponding power amplifiers is reduced, and the area of the PCB occupied by the power amplifiers is small and/or the cost is reduced.

In this embodiment, as shown in fig. 3, the communication terminal provided in the embodiment of the present application may be an electronic device such as a mobile terminal 100, a tablet computer, a notebook computer, and the like in the above embodiments, and the communication terminal includes a baseband processing unit 200, a radio frequency processing unit 300, and an antenna feeder system 400.

The transceiver 301 is a communication device, in which both the receiving part and the transmitting part are installed in a single chassis or rack, and is used for performing modulation processing on a signal to be transmitted and performing demodulation processing on a received signal.

Referring to fig. 3, the switch 202 is connected between the power module 207 and the first power amplifier 302, the first link 203 and the second link 204 are disposed between the power module 207 and the switch 202, and both the first link 203 and the second link 204 are connected to the power module 207, and the power module 207 can provide a first voltage to the first power amplifier 302 through the first link 203 or provide a second voltage to the first power amplifier 302 through the second link 204.

The switch 202 in this embodiment may be a switch chip, the switch 202 is connected to the processor 201, and the processor 201 controls the switch 202. The processor 201 is connected with the transceiver 301, and the processor 201 is used for receiving the network signal from the transceiver 301 and identifying the type of the network signal; the processor 201 generates or determines the first control information and the second control information according to the type of the network signal. Alternatively, the first control information is transmitted to the switch 202, and the switch 202 switches its connection state according to the first control information to connect the first power amplifier 302 to the first link 203 or the second link 204.

In one embodiment, the processor 201 may be connected to not only the switch 202, but also the processor 201 is connected to the power module 207. The processor 201 may transmit the second control information to the power module 207, and the power module 207 may provide a corresponding voltage to the first power amplifier 302 according to the second control information, i.e., the power module 207 may provide the first voltage to the first power amplifier 302 through the first link 203 according to the second control information; or a second voltage to the first power amplifier 302 via the second link 204; accordingly, at this time, the switch 202 switches the first power amplifier 302 to the corresponding first link or the second link, so that the first power amplifier 302 amplifies the corresponding different network signals.

Optionally, the network signals in this embodiment include a first network and a second network, the first network may be a 4G full-band signal, and the first network signals may include signals B1, B20, B33, B43, and the like. The second network signal may be a first frequency band range of the 5G signals, optionally the first frequency band range including N1, N2, N3, N5, N7, N8, N20, N28, N38, N41 signals.

Alternatively, when the processor 201 identifies the first network, the generated first control information includes a control signal corresponding to the first network, and transmits the control signal corresponding to the first network in the first control information to the switch 202, and the switch 202 can switch its connection state to the first link 203, even though the power module 207 and the first power amplifier 202 are connected through the first link 203.

It should be noted that, when the processor 201 identifies the second network, the generated first control information includes a control signal corresponding to the second network, and transmits the control signal corresponding to the second network in the first control information to the switch 202, the switch 202 can switch its connection state to the second link 204, even though the power module 207 is connected to the first power amplifier 302 through the second link 204.
