Abstract
An amplifying apparatus includes a first amplifier that amplifies an input signal on the basis of a value of a drain voltage and outputs a transmission signal, a distortion compensator that corrects a power amplitude of the input signal on the basis of a difference in power amplitude between the input signal and the transmission signal outputted from the first amplifier, a drain voltage controller that generates the drain voltage on the basis of the power amplitude of the input signal to be corrected, and a drain voltage corrector that corrects the drain voltage on the basis of the difference.
