Signal control circuit, terminal device, and signal control method

Abstract

The present invention provides a signal control circuit, a terminal device, and a signal control method. The signal control circuit includes a radio frequency transceiver, a power amplifier, a duplexer, a first antenna, and a second antenna. The signal control circuit further includes a switch module. A first contact point of the switch module is connected to a primary receive of the radio frequency transceiver, a second contact point of the switch module is connected to a first end of the duplexer, a third contact point of the switch module is connected to a diversity receive of the radio frequency transceiver, and a fourth contact point of the switch module is connected to the second antenna. A radio frequency transmitting end of the radio frequency transceiver is connected to an input end of the power amplifier, and an output end of the power amplifier is connected to a second end of the duplexer. In a first state, the first contact point and the second contact point are electrically connected, and the third contact point and the fourth contact point are electrically connected. In a second state, the first contact point and the fourth contact point are electrically connected, and the third contact point and the second contact point are electrically connected. In the present invention, power consumption of the terminal device can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a signal control circuit, terminal equipment and a signal control method. Background technique [0002] With the rapid development of terminal technology, terminal equipment has become an indispensable tool in people's life, and brings great convenience to all aspects of users' life. In the prior art, the radio frequency transceiver of the terminal device can receive the main set reception signal and the diversity reception signal. However, in some cases, the signal received by the radio frequency transceiver may be subject to some interference. In order to meet the communication quality of the terminal device, it is necessary to increase the transmission power, resulting in more power consumption of the terminal device.
