  • Author: Robert Eye, Applications Engineer

This paper addresses thermal issues with using QFN-packaged GaN power amplifiers, originally designed for pulsed operation, in CW mode. Consideration need to be made for component mounting to provide a low thermal impedance path to the system heat sink for optimum operation and reliability, using the TGA2307-SM as an example.
