Nonlinear Scattering Function Modeling Based on Harmonic Balance Mcthod

摘要

The classic modeling method based on s-parameter measurement cannot describe the nonlinear characteristic of the components accurately. Nonlinear scattering function model can describe the nonlinear characteristic from the perspective of qualitative and quantitative.In this paper,a new concept of nonlinear scattering funetion Is presented. Based on harmonic balance analysis,nonlinear scattering function model for microwave power components is extracted. The analysis of a power MESFET is used here as a vehicle to illustrate the concept of nonlinear scattering function and the new modeling method.
