PROJECT TITLE : SMALL LIGHT-WEIGHT ULTRA-HIGH-EFFICIENCY X-BAND SSPA FOR MICROSPACECRAFT
TECHNICAL ABSTRACT (LIMIT 200 WORDS)
It is highly desirable to replace bulky, failure prone, traveling wave tubes traditionally used for satellite downlinks with solid state components (SSPA's). However, despite steady progress, there remains a large gap between desired performance for microspacecraft applications (where prime power and allowable size and weight are at a premium) and current SSPA capability. Recently, Microwave Monolithics Incorporated (MMInc.) has developed a series of ultra-high-efficiency monolithic power amplifiers operating from UHF to L-Band which have demonstrated power-added efficiencies of 80%. MMInc. proposes to bring this performance to higher operating frequencies through materials enhancements, device scaling, and innovative circuit techniques. The result will allow MMInc. to "leapfrog" current SSPA technology, and construct reliable, ultra-high-efficiency X-Band power amplifier for microspacecraft applications. Detailed design and analysis of these devices and circuits in phase I will be followed by amplifier fabrication, characterization, and optimization in phase II.POTENTIAL COMMERCIAL APPLICATIONS
The proposed ultra-high-efficiency X-Band power amplifiers would find wide use in commercial space and terrestrial communications systems, as well as military and commercial phased array radars. The potential market for such solid state amplifiers is thus extremely large, and is currently limited by availability rather than demand.NAME AND ADDRESS OF PRINCIPAL INVESTIGATOR
