GaN solid state power amplifiers (SSPA) for wireless power transfer and microwave heating have been reviewed. For wireless power transfer, 9W output power with 79% power added efficiency at 5.8GHz has been achieved. For microwave heating, 450W output power with 70% drain efficiency at 2.45GHz has been achieved. Microwave power concentration and uniform microwave heating by phase control of multiple SSPAs are demonstrated.
