Nonlinear distortion compensation power amplifier |
摘要 |
A nonlinear distortion compensating power amplifier is provided with a gain adjustment circuit and performs gain adjustment control so that the overall gain of the entire system including a power amplifier is always maintained at a constant value. While this gain adjustment is being performed, a control circuit determines an optimum distortion amount pattern corresponding to instantaneous values of an input signal supplied to a distortion signal generation circuit to enable this circuit to generate a distortion signal such that the power of unnecessary out-of-band signal components in an output signal from the power amplifier is minimized.
