Abstract :
We report on a broadband high efficiency power amplifier using Indium Phosphide (InP) double heterojunction bipolar transistor (DHBT) technology. The amplifier demonstrated a record bandwidth for a class-E power amplifier at X-band. This circuit achieved 49-58% PAE, 18.5-23.9 dBm output power, and 9.6-10.5 dB gain across 9-11 GHz.
