Abstract
An amplifier may include a predistorter receiving an input signal to generate a predistortion signal, a first converter receiving the predistortion signal to generate a preamplified signal, a power amplifier receiving the preamplified signal to generate an output signal based on the preamplified signal and the input signal, and a second converter sampling the output signal to generate a feedback signal. The predistorter may separately and independently generate a predistortion signal component for the in-phase input signal and a predistortion signal component for the quadrature input signal.
