Abstract :
A frequency-domain spectral balance technique for the analysis of microwave circuits with analytically modeled nonlinear devices is developed. The technique uses linear matrix transformation of spectra to perform basic arithmetic operations-multiplication and division-in the frequency domain, and is termed the arithmetic operator method. A single MESFET amplifier described by the Curtice model is simulated with one- and two-tone excitation using this novel technique. Excellent agreement is obtained when compared to the results simulated using the conventional harmonic balance method.<>
