Abstract

In an embodiment, an apparatus includes: a modulator to modulate a first signal; a distortion circuit coupled to the modulator to digitally pre-distort the first signal to compensate for a distortion of an amplifier; a distortion characterization circuit coupled to the distortion circuit to determine the distortion of the amplifier and configure the distortion circuit based on the determined distortion; a mixer coupled to the distortion circuit to upconvert the pre-distorted first signal to a pre-distorted radio frequency (RF) signal; and the amplifier coupled to the mixer to amplify the pre-distorted RF signal and output an amplified RF signal.
