Abstract
Simulating an RF mixer includes mixing input and LO signals at an RF mixer and measuring a mixed output signal, where the input signal has a characterization RF frequency and the LO signal has a characterization LO frequency; determining spurious peak powers and spurious frequencies corresponding to the spurious peak powers of the mixed output signal; specifying a saturation condition of the RF mixer; determining equations defining frequencies of the mixed output signal in terms of the characterization RF and LO frequencies at the corresponding spurious peak powers; and simulating mixing of simulated input and LO signals to output a simulated mixed output signal from a mixer model corresponding to the RF mixer by applying the equations to the simulated RF and LO frequencies to determine simulated spurious frequencies, and simulated spurious peak powers and simulated spurious phases corresponding to the simulated spurious frequencies of the simulated mixed output signal.
