Patent ID: 7792214

Claim:
A transmitter circuit operable to generate and output a transmitted signal based on inputted data, comprising: a signal generation section for generating an amplitude signal and an angle-modulated signal based on an amplitude component and a phase component which are obtained by signal-processing the inputted data; a compensating filter for wave-shaping-processing the amplitude signal based on a predetermined characteristic of the compensating filter; a regulator for outputting a signal in accordance with a magnitude of the signal which has been wave-shaping-processed by the compensating filter; and an amplitude modulator section for, using the signal outputted from the regulator, amplitude-modulating the angle-modulated signal to be outputted as a modulated signal therefrom, wherein the predetermined characteristic of the compensating filter is an inverse of a transfer characteristic between an input at the regulator and an output at the amplitude modulator section.
