Abstract :
A single S parameter is sufficient for small signal networks analysis, but more mathematical tools are needed to describe and interpret the data resulted from large signal networks analysis. In this article, a SVM-based approach is adopted to describe nonlinear characteristic of RF power components: nonlinear scattering function. The nonlinear scattering function can build accurate behavior model of RF power components under large signal.
