    摘要: A distortion compensating apparatus used in a wireless communication device such as a portable phone. An information measuring unit (11a) measures a distortion component and an electric power component based on a radiation signal. A compensation coefficient calculating unit (11b) calculates a compensation coefficient based on the distortion component and the electric power component. A signal transmitting unit (11c) outputs a signal corrected by the compensation coefficient as a transmission signal. A signal converting unit (13) converts the transmission signal into a high frequency signal. An amplitude separating unit (15) amplifies the high frequency signal and separates a portion thereof as a signal to be fed back. A feeding-back unit (14) processes the separated portion and outputs the result as a feedback signal to the information measuring unit (11a). An electric power information extracting unit (16) outputs a portion of the high frequency signal as the radiation signal, extracts electric power information from the radiation signal, and directly outputs the electric power information to the information measuring unit (11a).
