摘要：
A new input-output matching structure is presented in this article. The proposed method is used to realize a wideband high-efficiency power amplifier. By combining the design of input-output matching network with a band-pass filter, the fundamental and harmonic impedances are transformed to high efficiency region. In this case, a continuous Class-F PA with wide bandwidth and high efficiency is obtained. Meanwhile, the bias circuit is also integrated in the matching network to simplify the wideband PA topology. After experimental verification, the fabricated PA has a measured drain efficiency of 62.2%-76.5% in the range of 1.35-2.8 GHz, with an output power of 39.1-42 dBm.
