How GaN On SiC Lowers 5G Base Station Costs


GaN’s higher efficiency at 5G frequencies compared with LDMOS also means a lower operating cost per bit/second and a lower carbon footprint. Wolfspeed, a Cree company, and dominant player in the GaN on SiC device market, estimates that GaN on SiC can save over 200 W of DC power compared to a system that uses LDMOS power amplifiers (PAs) when operated at maximum average power.
