RF/Microwave Amplifier Design Using Harmonic Balance Simulation With Only S-Parameter Data

It is widely held that S-parameters combined with harmonic balance (HB) alone cannot provide for the simulation of the power performance of transistors. This application note describes a method for designing and simulating amplfiers within NI AWR Design Environment for maximum power using HB simulation when the only available data is the S-parameters of the transistors. The method is widely applicable when nonlinear transistor models are not available and can also be very helpful even when the nonlinear models are available.
