MODELING the performance of an RP integrated circuit (RF IC), especial
ly one that translates frequency, can be difficult with conventional c
omputer-aided-engineering (CAE) tools, Fortunately, the advent of a CA
E modeling tool that combines aspects of frequency-domain and time-dom
ain simulation techniques can help accurately predict the nonlinear be
havior of high-frequency circuits when operating with complex waveform
