Abstract :
This paper discusses recent developments in Direct-Broadcast Satellite (DBS) television systems, and specifically how these developments are implemented using today´s MMIC technology. A brief review of Raytheon´s experience in supplying low cost GaAs devices to the commercial DBS market place is included. A description of a dual-channel downconverter is provided as an example of applying GaAs MMIC technology to the advanced technical needs of the DBS market. A discussion of the MPEG-2 digital compression standard and its relationship to DBS is also included
