GaN MMIC

PRFI has experience of designing GaN MMICs using the 0.25µm GaN-on-SiC processes of Wolfspeed (Cree), Qorvo, GCS, WIN Semiconductors and UMS. Our design activity has included Doherty PAs for sub-6GHz 5G, compact X-band PAs for phased array radar, very high linearity (high power handling) microwave switching functions, robust GaN LNAs, broadband GaN PA MMICs for ESM applications, and high linearity GaN PAs for point-to-point link applications.

mmWave 5G

5G communications systems offer huge increases in data rates and aim to provide a service with seemingly infinite capacity. This will be facilitated by the use of mmWave frequencies, where large bands of contiguous spectrum can be exploited. PRFI has designed MMICs and components for mmWave 5G systems operating in most of the bands including the 28GHz, 37GHz, and 39GHz bands, as well as the 26GHz “Pioneer Band” for 5G in Europe.
