摘要：
A Class-F power amplifier at 2.4GI-lz using a novel harmonic tuner based on a composite right/left handed (CRLH) transmission line (TL) is proposed and experimentally tested. Two structures are presented. One structure uses one open CRLH-TL stub to suppress 2(nd), 3(rd) harmonics and the fundamental frequency is matched to 50 Omega. The other structure uses two open CRLH-TL stubs in order to suppress 2(nd), 3(rd), 4(th) harmonics and the fundamental frequency is matched to a specific impedance. The structure proposed is used to design a class-F power amplifier. A maximum drain efficiency of 64% is obtained.
