This paper presents an ultra‐wideband, high‐efficiency continuous resistive‐reactive class‐J power amplifier. The design space is extended by controlling the second harmonic with impedance component and multiple harmonics of a continuous class‐J PA, enabling it to achieve efficient output in multiple octave bandwidths. Based on this theory, a GaN HEMT transistor CGH40010F is used to achieve a 0.6 to 3.2 GHz, average efficiency of 65%, ultra‐wideband PA with output power greater than 40 dBm. The simulation results are consistence with the measurement results and respond to the expectations.

高效连续电阻无功J类功率放大器的设计

本文提出了一种超宽带，高效率连续阻性无功J类功率放大器。通过控制具有阻抗分量的二次谐波和连续的J类PA的多个谐波来扩展设计空间，从而使其能够在多个倍频程带宽中实现有效的输出。基于此理论，GaN HEMT晶体管CGH40010F用于实现0.6至3.2 GHz，平均效率为65％的超宽带PA，输出功率大于40 dBm。仿真结果与测量结果一致，并符合期望。
