GaN: 100mm production amd 75W transistor

RF Micro Devices has released a 75W GaN RF unmatched power transistor, claimed to deliver superior performance against competing GaAs and Si transistors. Dubbed RF3932, it follows the recent release of the 140W RF3934, and operates from dc to 3GHz with peak efficiency over 65%. “It incorporates simple matching networks external to the package, providing wideband gain and power performance advantages in a si ...
