Abstract: In order to meet the needs of multi-party communication, complex wireless communication systems have high requirements for the power control of the RF unit. To determine the receiving and transmitting powers of the RF unit, it is inevitable to calibrate the receiving and transmitting modules separately. The calibration principle and calibration steps are described in detail, and a calibration result example is given. Python language is used to realize the automatic calibration of the transceiver module. This calibration method has high reliability, and can be extended to other RF units with power control requirements.

Key words: automatic gain control function, calibration, transceiver chip, loop gain
