Abstract
This letter presents a novel harmonic control circuit (HCC) for class-F power amplifiers (PAs). A compact microstrip resonant cell (CMRC) is inserted between the transistor and the output fundamental matching network. Third harmonic open circuit condition and size reduction are achieved simultaneously. This scheme provides a straightforward and simple approach to design HCC. A class-F PA is designed and fabricated for demonstration. The measured maximum power-added efficiency (PAE) is 74% with 10 dB power gain near the 1 dB compression point. © 2010 IEEE.
