Abstract:
A method of fabricating a solid state power amplifier (SSPA) having variable output power is provided. The method includes coupling a first transistor device to a second transistor device and biasing a drain input of each of the first and second transistor device. Further, the method includes biasing a gate input of each of the first and second transistor device varying a drain to source current of each of the first and second transistor device to enable the SSPA to maintain high power added efficiency (PAE) and consistent linearity over a range of output power levels.
