ABSTRACT:
A feedforward distortion compensation amplifier includes an adjusting unit for adjusting a gain and a phase of an input signal, a first amplifier for amplifying a signal outputted from the adjusting unit, a delay unit for delaying the input signal, and a coupler for coupling a signal outputted from the delay unit to a signal outputted from the first amplifier. The feedforward distortion compensation amplifier further includes a first controller which detects a distortion component of the first amplifier to control an operation of the adjusting unit based on the distortion component, and a second controller which determines one distortion level from distortion levels based on a magnitude of the input signal, and compares the determined distortion level with the detected distortion component of the first amplifier to control an amplification rate of the first amplifier based on comparison results.
