Abstract :
The design and performance of a 6-10-GHz heterojunction bipolar transistor (HBT) monolithic microwave integrated circuit (MMIC) power amplifier that produces 1.25 to 2.15 W at 30 to 46% power-added efficiency with 9.5 to 12.5 dB of power gain are described. With only 500 mu m/sup 2/ of output periphery, record MMIC HPA (high-power amplifier) power densities of 2.5 to 4.3 mW/ mu m/sup 2/ have been demonstrated.<>
