Gain calibration method for transceiver in communication module and communication module
By reserving material placement positions and installing fixed impedance components in the communication module, the impedance of the transceiver's transmit output port is located in the inductive region, which solves the problem of calibration failure in the Band 1 low-power level of the communication module, achieving a higher calibration success rate and reducing material loss and cost.

Abstract
The embodiment of the present application relates to the field of mobile communication, and discloses a gain calibration method for a transceiver in a communication module and the communication module. Before performing calibration on the transceiver in the communication module, a first material patching position in series is reserved at a transmitting output port of the transceiver and / or an output port of a filter connected with the transmitting output port; a fixed impedance element is attached and fixed on the first material patching position, and the fixed impedance element makes the impedance on the transmitting output port access of the transceiver after power-on be in an inductive region; then, the calibration operation is performed on the transceiver again, and the pass rate of the calibration of the transceiver can be significantly improved. The scheme can reduce material loss, reduce cost and improve the pass rate when the communication module is mass-produced.
