✦ Synopsis

Multiharmonic manipulation is presented as the most effective solution to improve power amplifier (PA) efficiency performances. Remarkable improvements in output power, power gain and power-added efficiency (PAE) are demonstrated, properly manipulating the input and output second and third harmonics, as compared to more classical design approaches. Experimental results at 5GHz confirm the feasibility, the validity and effectiveness of the proposed approach, increasing the maximum measured power-added efficiency from 39% to 61%.

## Abstract This paper describes a highly efficient class‐E power amplifier. The design has been carried out at 1 GHz using a LDMOS transistor with 10 W of peak envelope power (PEP). Drain efficiency of 76.1%, power‐added efficiency (PAE) of 73.6%, and gain of 14.8 dB are achieved at an output powe
