Wideband L-S band SiC power amplifiers

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.
