CMPA901A020

9.0 - 10.0 GHz; 20 W; Packaged GaN MMIC Power Amplifier

Wolfspeed’s CMPA901A020 is a packaged; 20W HPA utilizing Wolfspeed’s high performance; 0.15um GaN on SiC production process. The CMPA901A020 operates from 9-10 GHz and targets pulsed radar applications such as marine weather radar. With 3 stages of gain; this high performance amplifier provides >30dB of large signal gain; potentially lowering the transmit BOM count; and >50% efficiency to support lower system DC power requirements and simplify system thermal management solutions. Packaged in a small 6×6 mm plastic overmold QFN; the CMPA901A020 also supports reduced board space requirements and highthroughput manufacturing lines.

Thermal Considerations for High-Power GaN RF Amplifiers

Many RF applications require very long lifetimes with typical military and telecom use cases demanding more than 10 years of operation. Junction temperature Tj, or the temperature of the base semiconductor in the device, plays an important role in device reliability as does the substrate material in keeping the base semiconductor cool.
