Plextek RFI has just uploaded a new video tutorial on the design of GaN PA MMICs for use in 15GHz point to point microwave links, using Agilent's ADS software, and Cree's 0.25um GaN on SiC process. Emphasis is on designing GaN PAs for high linearity, rather than just saturated power. The resulting MMIC layout is somewhat smaller than commercially available GaAs die offering comparable performance.
