摘要
为适应多方通信的需求,复杂无线通信系统对射频单元功率控制有较高要求。要明确射频单元的收发功率,必然要对接收和发射模块分别进行校准。详细介绍了校准原理和校准步骤,并给出了一个校准结果样例。使用Python语言实现了收发模块校准自动化。这种校准方法具有较高的可靠性,可以推广到有功率控制要求的其他射频单元中。
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.
