とする非線形歪補償回路。[Claims for Utility Model Registration] A predistortion-type high-frequency amplifier that divides an input signal into two, passes one signal through a nonlinear distortion generation circuit, and vector-combines the distortion signal from the nonlinear distortion generation circuit with the other signal. In the nonlinear distortion compensation circuit, the nonlinear distortion generating circuit divides one signal into two and operates the divided signals as limiters at different limit levels, and the difference between the signals from each limiter circuit is calculated. 1. A nonlinear distortion compensation circuit comprising an output section that outputs the signal difference as a nonlinear distortion signal.
