2009 19th International Crimean Conference Microwave & Telecommunication Technology, 2009

Abstract

results of engineering and a research of wideband L-S band (0,5…2,5) GHz) amplifiers with CW output power from 20 to 200 Watt based on SiC-MESFETS are presented. It is included: (0,5…1) GHz (PM051) amplifier with output powers (182…269) W and efficiency (20…32) %; (0,8…1,6) GHz (PM0816) amplifier with output powers (117…137) W and efficiency (26…33) %; (0,8…2,5) GHz (PM0825–1) amplifier with output powers (21,5…27,8) W and efficiency (14…20) %. Fig. 1 and fig. 3 show output balanced chains of an amplifier.
