METHOD AND APPARATUS FOR ENHANCING PERFORMANCE OF DOHERTY POWER AMPLIFIER

摘要

An apparatus and method for enhancing performance of a Doherty power amplifier are provided. The method includes a signal separation unit for generating a first input signal serving as an input signal of a carrier power amplifier using an input signal and a second input signal serving as an input signal of a peaking power amplifier using the input signal, in which the first input signal is different from the second input signal.
