초록

A broadband watt-level power amplifier in a metamorphic high electron mobility transistor (mHEMT) technology is presented at K-band. The quadruple-stacked transistor is used to overcome the low breakdown voltage limit of mHEMTs and achieve watt-level output powers. The fabricated power amplifier using 130-nm mHEMTs shows an output power of 1.3 W at 18 GHz with a 3-dB power bandwidth of 58%. To the best of our knowledge, this is the first report of watt-level single-chip power amplifiers in mHEMT technology. (c) 2012 Wiley Periodicals, Inc.
