本文首次对“连续F类功率放大器”进行了理论介绍和实验验证，为高效、宽带功率放大器的设计提供了新的设计空间。从标准 F 类模式开始，这项工作表明，对于基波和二次谐波阻抗的耦合变化，可以保持恒定甚至改进的输出功率和效率。这项研究是在 GaAs pHEMT 器件上进行的，结果表明，在很宽的基波和二次谐波负载范围内，可以实现 82% 至 87% 之间接近恒定的效率以及 20dBm 的恒定输出功率。
This paper presents, for the first time the theoretical introduction and experimental validation of the “Continuous Class-F Mode Power Amplifier” that provides for a new design space for the design of high efficiency and broadband power amplifiers. Starting from the standard class-F mode, this work shows that it is possible to maintain constant or even improved output power and efficiency for coupled variations of fundamental and second harmonic impedances. The investigation was carried out on GaAs pHEMT devices and demonstrates that a near constant efficiency between 82% and 87% can be achieved along with a constant output power of 20dBm, over a wide range of fundamental and second harmonic loads.
