A 6–18 GHz broadband power amplifier MMIC with excellent efficiency

摘要

A three-stage monolithic microwave integrated circuit (MMIC) power amplifier from 6–18 GHz, which achieves high output power with excellent efficiency, is designed, fabricated and tested. Measured results show that the saturated output power and the small signal gain are about 32 dBm and 23 dB, respectively. Thus, the power added efficiency of about 28% indicates that it is useful in various communication systems.
