The manuscript details a harmonically-tuned power amplifier design methodology, that is based on the low-frequency experimental characterization of the time-domain I/V waveforms at the device current generator plane jointly with a model-based description of the device capacitances. The proposed approach, allowing to compute in a wide range of frequencies the optimal terminations at the design fundamental frequency and its harmonics, is particularly indicated for the design of wideband high-efficiency power amplifiers. Several experimental data, based on GaN technology, are proposed in order to prove the effectiveness of the methodology.

Abstract
The manuscript details a harmonically-tuned power amplifier design methodology, that is based on the low-frequency experimental characterization of the time-domain I/V waveforms at the device current generator plane jointly with a model-based description of the device capacitances. The proposed approach, allowing to compute in a wide range of frequencies the optimal terminations at the design fundamental frequency and its harmonics, is particularly indicated for the design of wideband high-efficiency power amplifiers. Several experimental data, based on GaN technology, are proposed in order to prove the effectiveness of the methodology.
