摘要：
This article 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 power-added efficiency (PAE) and output power over a 7.0 GHz bandwidth. The HPA's measured performance shows a PAE range of 82 to 50 per-cent and an output power of greater than 25 dBm across a 7 to 14 GHz, band. The new broadband load also allows the HPA to have an excellent, spectrally pure frequency response demonstrated by its low AM and PM noise. A single 0.25 X 720 mu m GaAs PHEMT device is used in this circuit.
