Abstract
Classic linearization of a radiofrequency (RF) Power Amplifier (PA) is based on measuring its response to a representative test signal in order to extract pre-distortion parameters. Characterizing an RF PA under 3GPP Long Term Evolution (LTE) RF signals requires high speed data acquisition instruments and customized algorithms to estimate its response. In this work, a PA linearization method using a generic probing signal to extract pre-distortion parameters is proposed. A GaN HEMT Class-AB structure is tested to demonstrate the effectiveness of the proposed linearization method.
