Abstract
We have developed a highly efficient two stage X-band MMIC high power amplifier. Based on an optimized PHEMT device structure and a novel design approach, the amplifier demonstrated an average power added efficiency of 55% and an output power of 5 watts. A peak efficiency of 60% at near 8.0 GHz was obtained. The average drain current is 1.4 A at 7.0 V drain voltage. This is the highest reported efficiency for a broad-band, high power amplifier at X-band frequencies.
