Abstract
A straightforward synthesis method for the optimisation of harmonic loading of high-efficiency class-AB microwave power amplifiers is presented. Amplitudes of harmonics are determined that optimise the output voltage and current waveforms in a realistic case; simple formulae are given for the synthesis of the loads. Results and comparisons with a standard design are presented that show the improvement in output power and efficiency
