The task of designing frequency multipliers and comb generators has traditionally been plagued by challenges such as low output power, unexpected parasitic frequencies, and oscillations. Computer-aided-design (CAD) software can overcome these problems, though. The purpose of this work is to predict the behavior of a nonlinear step-recovery diode (SRD) in a harmonic-generator circuit. By doing so, one can achieve high correlation between simulation results and measured data...
