The Design of High Power 12 GHz Microwave Components for Use in Broadcast Communications Satellite Systems

A number of broadcast satellites operating in the 12 GHz band are scheduled for launch in the next decade. This paper presents a status report on a long term program aimed at advancing the technology of microwave components capable of forming the building blocks of the high power output circuits of such satellites. Designs are described and results presented on (a) devices qualified for use in a 12 GHz experimental satellite at power levels of up to 300 Watts, and (b) components currently being designed to operate in satellites with output powers up to 1 KW.
