Abstract
An apparatus includes a first predistorter configured to calculate a first predistortion parameter and configured to distort an input signal using the first predistortion parameter to output a first distortion signal, a second predistorter configured to calculate a second predistortion parameter and configured to distort the first distortion signal using the second predistortion parameter to output a second distortion signal, a power supply configured to receive the first distortion signal to generate a first envelope signal, and configured to limit a bandwidth of the first envelope signal to obtain a second envelope signal to supply a source voltage, and a power amplifier configured to receive the source voltage and to output an output signal obtained by amplifying the second distortion signal.
