摘　　要：微波高功率无源收发转换系统,集微波半导体器件应用技术、电路综合设计技术于一体,在本机发射脉冲期间对进入收发转换系统的功率实现闭环吸收,在接受回波期间呈现低耗通道,对弱小信号实现有效传输。微波高功率无源收发转换系统工作方式无需外加同步控制信号,对来自临近雷达或电子设备的异步电磁波具有独特的抗干扰能力。Microwave high power passive T/R conversion system is combined by the application technology of microwave semiconductor device and the synthetic design technology of electrocircuit,which can absorb power in closed loop when pulse emitted by transmitter,and also can transport small signal effectively in low energy dissipation channel when it receives echo.The system needn＇t extra synchronous control signal,but it has the unique anti-jamming ability to asynchronous electromagnetic wave of nearby radars or electronic equipments.
