A new UHF Solid State Power Amplifier (SSPA) has been developed for use in government mobile communications space programs. Predistortion linearization combined with high-voltage gallium nitride (GaN) FET technology allows the simultaneous achievement of both linearity and record high linear efficiency. This SSPA is capable of a peak power of more than 170 watts, but will be operated at a lower power (60 watts) to provide the reliability required for service in space and the linearity needed for WCDMA operation. A power added efficiency (PAE) of greater than 60 % was achieved at this operating point.
