Patent ID: 7116951

Claim:
A transmitter circuit comprising: a power control error data generator operative to receive amplitude modulation data and a RF coupled output signal and in response to produce power control error data; a feedforward predistortion data generator, operative to receive the amplitude modulation data and in response to produce feedforward predistortion data; feedforward adder logic, operatively coupled to the power control error data generator and to the feedforward predistortion data generator, and operative to receive the power control error data and the feedforward predistortion data and, in response, to produce power control data; and an amplifier, operatively coupled to the feedforward adder logic, and operative to receive the power control data and a radio frequency (RF) input signal and in response to produce an RF output signal, wherein the RF coupled output signal is associated with the RF output signal and wherein the power control data reduces amplitude modulation distortion in the RF output signal.
