The experimental results of Sl-GaAs ultrafast photoconductive photoconductive switches with all-solid-state isolation and microstrip line low-inductance output are given as high power sub-GHz electromagnetic pulse microwave sources. The nonlinear characteristics of the initiation, maintenance and recovery process of semiconductor photoconductive switches under high electric field are summarized. The principle and performance of the ultrafast photoconductive photoconductive switch as the pulse source of the electromagnetic missile and the application prospect of the ultrashort electromagnetic pulse in the fields of ultra-wideband radar and ultra-wideband communication are expounded.
