Even if the sampling rate of the D / A converter is low, to suppress deterioration of the distortion compensation performance. It was provided with a power amplifier and amplifier unit, and the distortion compensation unit, removing a first rate converter and a first signal converter. It amplifies the converted analog signal to the amplifier section input signal. The distortion compensation unit performs the predistortion processing the input signal to a second sampling rate higher than the first sampling rate for converting an input signal into an analog signal. The predistortion processing unit is removed from the input signal conducted to remove the frequency component exceeds the frequency band of the first sampling rate. First rate converting unit converts the sampling rate of the input signal frequency component is removed to the first sampling rate from the second sampling rate. The sampling rate converter may convert the first signal is the analog signal to convert the input signal to the first sampling rate, and outputs the transformed input signal to the amplifier section.
