【摘要】 介绍了一种用于冲激引信系统中的超窄脉冲产生电路。文章对阶跃恢复二极管的特性进行了分析,并利用它的这一性质设计了超窄脉冲产生电路。用重复频率为50MHz的晶体振荡器作激励源,该电路能产生脉宽小于1ns,幅度为6.2v的窄脉冲信号。且脉冲的拖尾振荡起伏小,是一种适用于冲激引信系统的超窄脉冲产生电路。更多还原

【Abstract】 This article introduced one kind of ultra narrow pulse electric circuit,it is suitable in the impulse fuze system.We also analyzed characteristics of the step-recovery diode,and designed the ultra narrow pulse electric circuit by using this nature.Makes the drive source with the 50MHz crystal oscillator,this electric circuit can produce the narrow pulse with width to be smaller than 1ns.the scope is the 6.2v. Also the pulse trailing vibration fluctuates slightly,Therefore this ultra narrow pulse electric circuit is suits to the impulse blasting fuse system.更多还原
