摘要： PROBLEM TO BE SOLVED: To provide a distortion compensating device generating larger distortion components than current distortion generating amplifiers.
SOLUTION: The distortion compensating device is provided with a particular distortion generating circuit 17. The distortion generating circuit 17 distributes an input signal input to an input terminal 16 into two lines in an electric power distributor 51, and synthesizes outputs from the two lines in an electric power synthesizer 56. A first phase shifter 52 and a first distortion generator 53 are inserted to be connected in series with one of the two lines, while a second phase shifter 54 and a second distortion generator 55 are inserted to be connected in series with the other line. The first phase shifter 52 and the second phase shifter 54 are configured in such a way that a phase difference between an signal input from the first phase shifter 52 to the electric power synthesizer 56 via the first distortion generator 53, and an signal input from the second phase shifter 54 to the electric power synthesizer 56 via the second distortion generator 55, is 180 degree so that a double-level distortion component is output in comparison with the current devices.
