Abstract

An improved “generic” pre-distortion method is tested and successfully demonstrated on the recently introduced Class-J power amplifier (PA) architecture. This linearization method is based on AM-AM and AM-PM measurements in the presence of a narrowband multi-tone signal in order to extract the PA static nonlinearities. Two independent measurement systems have been used to verify the assumption on which the generic linearization method relies. The use of a modulated, time-domain waveform measurement system in the presence of multi-tones signals has allowed unique investigations into the Class-J PA linearity.
