摘　　要：以固态半导体器件为基础,基于超快电子学中的晶体管雪崩导通理论,利用脉冲耦合原理,在时域上将多路高压皮秒脉冲耦合输出,获得了超宽带高功率脉冲。通过四路脉冲耦合实验验证了该设计思路的可行性,提高了输出脉冲功率。实验中,单路高压皮秒脉冲的幅度为1.33kV,宽度为770ps,峰值抖动≤1%,脉宽抖动≤1%,四路脉冲耦合后,输出脉冲幅度为2.66 kV,宽度为875 ps,峰值抖动≤1%,脉宽抖动≤1%。该方法可以推广至多路脉冲耦合,获得更高的功率。Based on solid state semiconductor devices and transistor avalanche theories of ultra-fast electronics,with pulse coupled method,multi-channel high-voltage picoseconds pulses were coupled in the time domain,and the ultra-wideband,high-pulse was obtained.The feasibility of the design was confirmed by four-channel pulse coupling experiment with the result of the output pulse power was increased.The experiment with amplitude of 1.33 kV,pulse width of 770 ps and jitter of less than 1% are generated by MARX circuits firstly.After the four pulses coupled,the output pulse will be with 2.66 kV,875 ps and less than 1% in amplitude,width and jitter,respectively.This method can be extended to multi-channel pulse coupling to obtain higher power.
