With regard to wideband predistortion type power amplifiers, such as shared amplifiers used in W-CDMA base stations, the memory effects associated with RF power amplifiers degrade power efficiency. Aiming to solve this problem, we find that a high-voltage compound semiconductor device has sufficient
