In this paper, a spectral method based on the memoryless predistortion technique is presented to identify accurately the memory effects of wideband RF power amplifiers stimulated by practical modulated signals. According to this new definition of the memory effects, a novel metric to measure quantitatively the memory effects in wideband power amplifiers is proposed. With the proposed memory effect metrics, the intensity of the memory effects for different power amplifiers, under a variety of the excitation modulated signals, can be quantitatively evaluated.
