Second octave power amplifier design based on resistive-reactive series of continuous inverse modes

摘要

This Letter presents a methodology, which contains resistive-reactive series of continuous inverse modes (Res.-Rea. SCIMs), for the second octave power amplifier (PA) design. The bandwidth was extended by multiplying the current waveform of SCIMs with a cosine factor. The measurement of the proposed Res.-Rea. SCIMs PA showed 67-78.8% drain efficiency and ~10 W output power across a band of 0.5-2 GHz.
