Load-Pull Measurements Oriented to Harmonically-Tuned Power Amplifier Design
In this paper we investigate the complexity of the characterization of electron devices with microwave load-pull systems when harmonically-tuned classes of amplification are adopted. In particular, we highlight the effects of the transistor dynamic nonlinearities on the load impedances at the transistor current-generator plane.
