Abstract:This paper describes the successful insertion of a high yield 4-W GaAs X-band power MMIC into the solid-state transmitter of the MODular Avionics Radar (MODAR) weather system. To date, over 15000 4-W MMIC's have been delivered with a combined ddRF test yield averaging 39%. The design and fabrication of the MMIC's are presented along with statistical test data on over 46000 MMIC's. The integration of the MMIC's into a higher level 12-W hybrid assembly and an 85-W power module are also discussed. Two 85-W module… Show more
