Abstract :
Advanced millimeter-wave systems require high efficiency MMIC power amplifiers to reduce physical size, weight, and prime power consumption. A high-efficiency MMIC power amplifier was developed using 0.15 um InP-based (Al/sub 0.48/In/sub 0.52/As-Ga/sub 0.47/In/sub 0.53/As) HEMT MMIC technology. The amplifier demonstrated state-of-the-art power performance, including 33% power-added efficiency and 24 dBm output power at 44 GHz. Potential applications include communication terminals and phased array antennas.<>
