Abstract :
This paper presents a new macro modeling methodology for solid-state amplifiers (SSAs) or packaged transistors used in communication systems. The model topology is based on the principle of the harmonic superposition recently introduced by the Agilent X-parameters(TM) combined with dynamic Volterra theory. The model results on a Multi-harmonics Bilateral model which handles short-term memory effects. In this work, the behavioral model developed was extracted from time domain load pull measurement performed on one amplifier. Then, the model was used for the simulation of the amplifier´s response using a two tones and a CW signal under moderate mismatched load operating conditions.
