摘要

This paper investigates optimum load synthesis methods for wideband multi-carrier compatible power amplifiers (PAs) using active modulated load-pull analysis. The analysis demonstrates that frequency-dependent optimum impedance enhances the power added rfficiency (PAE) up to 3-5% and the gain up to 1-2dB near and beyond the 1-dB compression. The proposed optimum impedance synthesis approach offers...
