An uncorrelated adaptive predistorer configured for use with an RF power amplifier having an input loop configured to be coupled to the input of the RF power amplifier an output loop coupled to the output of the RF power amplifier. Such an input loop includes a look-up table containing predistortion values to be apply to an input signal, in response to a monotonically increasing function of the input signal power, for forming a predistorted input signal. Such an output loop configured to measure an intermodulation distortion product of the RF power amplifier output resulting from the predistorted input signal, and operable to update the predistortion values in the look-up table.
