Paper Abstract

High efficiency power amplifier design criteria, in the microwave and millimeter wave frequency range, are reviewed and discussed. An approach to clarify the relevance of both input and output harmonic terminations is presented. Starting from power balance expressions, design criteria to improve efficiency for high frequency application are derived. In order to validate the approach, experimental harmonic source pull results, and comparisons among performances of single-stage amplifiers, synthesized utilizing different design methodologies, are presented.
