A high‐efficiency power amplifier by using harmonics control

A harmonics control high‐efficiency power amplifier (PA) is proposed by combining an asymmetrical branch‐line coupler (ABLC) and a shunt transmission line. With the special ports impedance condition, the ABLC realizes impedance transformation as well as shorts even‐harmonics, and the shunt transmiss...
