METHOD OF CHARACTERIZING NONLINEAR BEHAVIOR OF AMPLIFIERS USING LOADPULL MEASUREMENTS

摘要

A behavioral modeling technique is provided that is based directly on the loadpull gain and phase compression measurements. Developed from the large-signal scattering function theory, this technique shows the possibility to generate the large- signal scattering function model using traditional toadpull measurement systems. The large-signal scattering function theory is presented and the analogy between the LSNA and the loadpull measurement systems is drawn. A detailed analysis of the model generation process is further taught herein.
