Abstract
An amplifier system containing a polynomial predistorer and a polynominal predistorter configured for use with an RF power amplifier, the polynomial predistorter having a polynomial generator configured to receive an RF input signal and generate a predistortion function based thereon, and a combiner circuit also configured to receive the RF input signal and coupled to the polynomial generator and configured to combine the RF input signal with the predistortion function to form a predistorted input signal, the predistorted input signal operable to improve the adjacent channel power and/or the error vector magnitude performance of the RF power amplifier.
