<p>Providing a distortion compensating device which can significantly remove residual distortion. The value of the matching circuit 11 is set up so that the distortion generated at the gain controlling unit 9 offsets the distortion remaining in the power amplifier 12. That is, the value of the matching circuit 11 is set up so that the phase of the residual distortion included in the output of the matching circuit 11 is rendered opposite to the phase of the residual distortion included in the output of the power amplifier 12. Thus, the residual distortion included in the output of the power amplifier 12 is offset by the residual distortion included in the output of the gain controlling unit 9, thereby the residual distortion can be removed. <IMAGE></p> |
