Multi-Stage Power Amplifier Reference Design Guide For Military Communications, Operating at 50 V and 100 W

Wolfspeed, a Cree company, has developed application fixtures for three catalogue devices; the CMPA0527005F, CGHV40030F, and the CGHV40100F to cover 0.5 GHz to 2.5 GHz for Electronic Protect/jamming power amplifier, and other military communications (MilCom) applications. All devices are constructed with Wolfspeed’s GaN HEMT technology with the CGHV40100F and CGHV40030F being unmatched devices operating at 50V. The CMPA0527005F is a GaN MMIC device with the input matched to 50 Ohm and the output unmatched also operating at 50V. This whitepaper describes the typical performance that has been achieved when three fixtures are assembled together.
