High-efficiency InP-based HEMT MMIC power amplifier

High-efficiency monolithic Q-band power amplifiers were developed using InP based HEMT MMIC technology. The amplifiers demonstrated state-of-the-art power performance including 33% power-added efficiency and 26 dBm of output power at 44 GHz. This is the highest output power reported with such a high efficiency for InP-based HEMT MMIC power amplifiers at Q-bands. The intended application is communication terminals. >
