Abstract

SummaryWe propose a broadband high‐efficiency power amplifier (PA) with output power between 42.6 and 44.7 dBm, drain efficiency (DE) over 62%, and power additional efficiency (PAE) over 52% in the 2.3–3.5GHz frequency band. This PA effectively combines the high‐efficiency characteristics of class‐F PAs with the advantages of controlling the second harmonic for obtaining high efficiency at large bandwidth. The Dual Band Harmonic Control and Matching Network (DBHCN) realizes the conversion from 50 Ω to high‐efficiency impedance space (HEIS) while controlling the high‐order harmonics in different frequency bands. The proposed PA can be used for the fifth‐generation mobile communication technology (5G) base stations and broadband radars.
