Memory effects are defined as changes in the amplitude and phase of distortion components caused by changes in modulation frequency. These are particularly important in cancelling linearizer systems, e.g., when distortion is reduced by similar distortion in the opposite phase. This paper begins by d
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
