This chapter gives a brief overview of monolithic microwave amplifiers on GaAs with particular emphasis on low-noise preamplifiers for radars and communications and wide-band amplifiers for electronic countermeasures and instrumentation. Two particular design techniques have been examined - conventional passive matching and feedback, with examples of MMICs produced being given.
