Summary: 
An impulse generation circuit using an SRD was made as an experiment. The circuit, which is used for UWB pulse radars, etc., was designed using PSpice, a SPICE simulator. Since there is no SRD model in SPICE, the pn junction model was substituted. The experimental and simulated waveforms were compared, and could be made almost to match by adjusting the parameters of the SPICE diode model.
