A Highly Efficient 7 to 14 GHz Monolithic Class-E Power Amplifier

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 percent 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 × 720 μm GaAs PHEMT device is used in this circuit.
