PRFI Completes 5.5W GaN PA for CML Micro

PRFI is pleased to report the successful completion a 5.5W (37.4dBm) mmWave GaN-on-SiC Power Amplifier development for CML Micro, a leading UK supplier of RF and microwave MMICs. It covers a frequency range of 27.5 to 31GHz and has been optimised to provide a cost-effective solution for high-volume Ka-band satcom and FR2 5G applications. 50Ω RF input and output and dual-side biasing simplifies integration into an RF subsystem.

The PA was designed on a world-leading 0.15µm GaN-on-SiC process and packaged in an air-cavity plastic QFN package measuring 4x4mm that was optimised for RF and thermal performance. Further details will be available from CML Micro (booth #551) at the International Microwave Symposium (IMS) in Washington DC, June 18-20.
