Abstract

A novel Class E/F power amplifier (PA) with wide bandwidth is presented in this paper. The proposed approach is used to realize a high-efficiency PA. By introducing an additional shunt capacitance into the original circuit, a harmonic control network is obtained, which satisfies the load impedance requirements of Class E/F PA at odd and even harmonics, while simultaneously matching the fundamental impedances to a 50 Ω load. Experimental verification shows that the fabricated PA achieves a measured drain efficiency (DE) of 67.2%–79.2% in the range of 1.9–3.0 GHz, with an output power of 40.2–43.0 dBm.
