Nonlinear Modeling of RF/Microwave Circuits for Multi-Tone Signal Analysis

Supported on the theoretical framework of Volterra Series, the present paper discusses nonlinear model extraction procedures currently in use for multi-tone signal analysis, and proposes a methodology that has been successfully applied to small and large-signal distortion regimes of microwave circuits. Good agreement between nonlinear simulation results and laboratory measurements of a medium power amplifier driven with band-limited white noise, validated the authors' approach.
