摘要：
A distortion compensation amplification device which supplies a transmission signal while a distortion of the amplified transmission signal is compensated, the distortion compensation amplification device including a correction unit which corrects a carrier leak and an image of the transmission signal based on a correction value. The distortion compensation amplification device includes a modulation unit which modulates the transmission signal supplied from the correction unit. The distortion compensation amplification device includes a correction value calculating unit which calculates the correction value based on the transmission signal supplied from the modulation unit. The distortion compensation amplification device includes a test signal output unit which supplies a test signal to the correction unit in order to calculate the correction value of the correction value calculating unit when the transmission signal is not transmitted.
