摘　　要：本文设计了一种射频通道微波开关的故障检测方法,并基于此方法研制了一种射频通道微波开关的故障检测组件。该组件可以在不明显增加使用微波开关的大功率功放或大功率收发组件重量、体积,不增加发射通道插损、驻波的情况下,明显提高射频通道微波开关的可靠性和使用寿命,同时提供了大功率击穿报警信号和故障检测信号。A fault detection method of RF channel microwave switch is designed,and a fault detection module of RF channel microwave switch is developed based on this method.This module can significantly improve the reliability and service life of RF channel microwave switch without significantly increasing the weight and volume of high-power amplifier or high-power transceiver module using microwave switch,and without increasing the insertion loss and standing wave of transmission channel.The module also provides high-power puncture alarm signal and fault detection signal.
