Abstract

A signal transmission method and a communication circuit, the communication circuit is applied in a wearable device, and the communication circuit includes a main control chip, a radio frequency transceiver chip, a radio frequency power management APT chip, a transmission module TxM chip and an antenna module, wherein: the main The control chip sends the first radio frequency signal information to the radio frequency transceiver chip and the APT chip; when the radio frequency transceiver chip receives the first radio frequency signal information, it sends the first radio frequency signal to the TxM chip; when the APT chip receives the first radio frequency signal information, The control voltage is output to the TxM chip; the TxM chip adjusts and filters the power of the first radio frequency signal under the control of the control voltage, and obtains and sends the second radio frequency signal to the antenna module; the antenna module receives and outputs the second radio frequency signal to the outside world. By implementing the embodiments of the present invention, the emission consumption of the wearable device can be reduced, thereby improving the endurance of the wearable device.

Description

technical field [0001] The invention relates to the technical field of wearable devices, in particular to a signal transmission method and a communication circuit. Background technique [0002] The traditional way for a smart watch to output 4G radio frequency signals is usually to amplify the power of the 4G radio frequency signal output by the radio frequency transceiver chip through a multimode multiband power amplifier (MMMB PA), and pass the amplified signal through the first transmission circuit. The 4G radio frequency signal is sent to the surface acoustic wave filter (Surface Acoustic Wave, SAW) at the transmitter, and then the amplified 4G radio frequency signal is filtered through the transmitter SAW, and then the filtered 4G radio frequency is further sent through the second transmission circuit The signal is sent to the antenna, so that the antenna outputs the filtered 4G radio frequency signal. In practice, it is found that there are two transmission circuits i...
