Abstract
This paper describes the design and fabrication of a highly efficient broadband monolithic class-E power amplifier utilizing a new distributed class-E load topology. The amplifier maintains a simultaneous high PAE and output Power over 7.0 GHz of bandwidth. The HPA's measured performance shows a PAE range of (50 % to 82 %) and an output power of >25 dBm across 7-14 GHz. The new broadband load also allows the HPA to have excellent spectrally pure frequency response demonstrated by its low AM and PM noise. A single 0.25 um x 720 um GaAs pHEMT device is used in this circuit.
本文介绍了一种利用新型分布式e类负载拓扑结构的高效宽带单片e类功率放大器的设计和制造。放大器同时保持高PAE和输出功率超过7.0 GHz的带宽。HPA的测量性能显示PAE范围为(50%至82%)，7-14 GHz的输出功率>25 dBm。新的宽带负载还使HPA具有出色的频谱纯净频率响应，其低AM和PM噪声证明了这一点。该电路使用单个0.25 um x 720 um的GaAs pHEMT器件。
