This paper describes the key role that GaAs MMIC devices are playing in the development of cost-effective front-end components for mm-Wave Satellite Communications (SATCOM) ground terminal equipment, terrestrial LMDS and point-to-point / point-to-multi-point distribution systems.  We present an overview of the development of two specific examples.  The first is a MMIC based 19/29 GHz dual-channel transceiver for terrestrial or ground-terminal applications, and the second demonstrates how GaAs MMIC devices form the heart of a 2-Watt, 29 GHz transmit module for a specific SATCOM system currently being deployed throughout Europe.
