Design of Broadband High-Efficiency Power Amplifiers Based on a Series of Continuous Modes

Abstract: In this letter, a series of continuous modes for designing broadband high-efficiency power amplifiers (PAs) are proposed, which extend the continuous mode concept. The impedance solutions space based on these modes offer a greater freedom for realizing broadband high-efficiency PAs. To verify this theory, a high-efficiency PA over a 54.5% bandwidth from 1.6 to 2.8 GHz is designed. The simulated results show that the fundamental impedances in this PA are found to be in good agreement with the calculated ones. M… Show more

“…However, the matching network, combined with the parasitics, can not keep the real part of fundamental impedance constant over a desired bandwidth. Therefore, other PA modes [5,6] based on Class-J or continuous Class-F are proposed to extend the design space of fundamental and second harmonics, and also the bandwidth.…”
