<p>PROBLEM TO BE SOLVED: To provide a pre-distortion compensation circuit that requires less memory for compensation data.SOLUTION: The pre-distortion compensation circuit includes: a first compensation section that has first compensation data which compensate for a nonlinearity of an input-output characteristic of a power amplification section at a reference temperature, and performs a compensation process on an input signal according to one of the first compensation data which corresponds to an output power detection value of the power amplification section; and a second compensation section that has second compensation data which compensate for a characteristic difference between a gain deviation characteristic of the input-output characteristic of the power amplification section at a non-reference temperature and a gain deviation characteristic at the reference temperature, and performs a compensation process on the input signal subjected to the compensation process in the first compensation section according to one of the second compensation data which corresponds to a temperature detection value of the power amplification section.</p> |
