Abstract
A nonlinear distortion detection device that includes a test signal generator that generates a test signal and outputs the test signal to have the power amplifier amplify the test signal, a Fourier transformer that converts an output signal of the power amplifier to a signal in a frequency domain, and a distortion factor calculator that calculates a distortion factor of the power amplifier based on amplitude information and phase information of the signal in the frequency domain.
