摘要：

A methodology for designing concurrent dual-band high efficiency power amplifiers (PAs) is presented in this letter. Load-pull simulations based on active device model are performed in two different bands to find the optimal required impedance conditions. A novel matching network with up to third order harmonic control is proposed to realize the high-efficiency mode matching in the two designed bands. A 1.9/2.6 GHz GaN PA is then designed to verify this method. The realized dual-band PA delivers above 10 W output power with more than 74% drain efficiency in the both operation bands.
