NONLINEAR DISTORTION COMPENSATION POWER AMPLIFIER

摘要

A nonlinear distortion compensation power amplifier wherein a gain adjustmen t circuit (4) for gain adjustment control is provided to maintain the overall gain of the nonlinear distortion compensation power amplifier comprising a power amplifier (5) always to a constant value, a control circuit (8) determines most suitably the pattern of the amount of distortion correspondi ng to the instantaneous value of the input signal given to a distortion signal generating circuit (3) so that the distortion signal generating circuit (3) can generate such a distortion signal that the power of the unnecessary out- of- band signal component of the output signal of the power amplifier (5) may be minimum while the overall gain is maintained.
