Abstract

The invention relates to a signal transmission method and a signal transmission circuit. The signal transmission circuit is applied to a wearable device. A master control chip sends first RF signal information comprising frequency information of a 2G signal matching first RF signal information to an RF transceiver chip, and sends a power level of acquiring the first RF signal according to the frequency information of the first RF signal to an APT chip; the RF transceiver chip sends the first RF signal to a TxM chip; the APT chip outputs a control voltage matching the power level to the TxM chip; the TxM chip adjusts the power of the first RF signal and filters the first RF signal under control of the control voltage so as to obtain a second RF signal, and sends the second RF signal to an antenna module; and when receiving the second RF signal, the antenna module outputs the second RF signal. Through adoption of the signal transmission method and the signal transmission circuit, the emission power consumption of the wearable device is lowered, and further the endurance performance of the wearable device is improved.

Description

technical field [0001] The invention relates to the technical field of wearable devices, in particular to a signal transmission method and a signal transmission circuit. Background technique [0002] At present, wearable devices usually use the 2G power amplifier (Power Amplifier, PA) inside the transmission module (Transmit Module, TM) to realize the power amplification of the 2G radio frequency signal, wherein, the existing TM uses the battery voltage (voltage battery, VBAT) to bias the PA. In practice, it is found that the bias voltage provided by VBAT for the PA remains unchanged, which increases the transmission power consumption of the wearable device when the signal transmission power is small, thereby reducing the endurance of the wearable device. . Contents of the invention [0003] The embodiment of the present invention discloses a signal transmission method and a signal transmission circuit, which can reduce the transmission consumption of a wearable device, ...
