A low distortion power amplifier, where N is greater than 1, comprising an input divider (10) for dividing a received input signal (100), and outputting a first signal (104) and a main signal (102), a carrier cancellation component (50) connected to the input divider (10) for receiving the first signal (104) and outputting a distortion signal (114), an input attenuator (22) receiving the main signal (102) and outputting an attenuated main signal (118) to an input delay device (24) yielding a delayed, attenuated main signal (118), and an N way distortion cancellation component (52) having a first input connected to the carrier cancellation component (50) for receiving the distortion signal (114) and a second input connected to the input delay device (24) for receiving the delayed, attenuated main signal (118) and an output for outputting an amplified output signal (144) having low distortion.
