HIGH-EFFICIENCY, FLAT GAIN5-WATT X-BAND MMIC, FOR LARGE VOLUME PRODUCTION
HfGH-EFFICIENCY, FLATGAIN5-WATT X-BAND MMIC, FOR LARGE VOLUME PRODUCTION D. Raicu, J.R. Basset, C.R. Baughman, Y. Chung, D.S. Day, C. Hua* ABSTRACT A power amplifying X-band MMIC is reported, that delivers SW saturated power over a 27% bandwidth. It was developed for operation at constant input power and with a restricted gain compression throughout its frequency range. Under these conditions, g
