Validation of the high-order polynomial models used in behavioral-level simulation

Behavioral-level simulation techniques are very popular for system-level simulation of RF and microwave communication systems. Appropriate models of nonlinear transfer characteristics of active (nonlinear) stages are required for the simulation. This paper begins with a discussion of such models. Their validation using measured data as well as harmonic balance (HE) simulation data are presented in detail. The discrete technique implemented in MathCAD was used for the simulation.
