摘　　要：给出了阶跃恢复二极管(SRD)的电压跃变模型以及SPICE仿真参数,分析讨论了基于SRD仿真模型的超宽带引信脉冲源的设计,并利用PSPICE仿真软件对设计的电路进行了仿真。实际制作的电路可以输出脉冲宽度250ps,重复周期100MHz,幅度达5V的亚纳秒窄脉冲信号。测量结果和仿真结果比较吻合,说明给出的SRD模型及仿真设计方法在超宽带引信信号源的设计中具有一定意义。A voltage-switch model for step recovery diode（SRD） and its SPICE simulation parameters are presented. The SRD-model-based design of the pulse generator for Ultra-WideBand（UWB） fuze is explicitly discussed and its performance is predicted by PSPICE simulation. The proposed pulse generator produces 250ps sub-nanosecond pulses with about 5V peak-to-peak and a pulse repetition rate of 100MHz. Measured pulses have good agreement with simulation results, which indicates that the SRD model is considerably useful in the design of UWB pulse generators.
