Abstract: A high efficiency power amplifier is provided. The amplifier includes a drive amplifier and latter power amplifier. The amplifier also includes a first digital pre-distortion correction module for pre-distortion processing the non-linear characteristics of the drive signal outputted by the drive amplifier; A second digital pre-distortion correction module connected to the first digital pre-distortion correction module in series for pre-distortion processing the non-linear characteristics of the amplification signal outputted by the latter power amplifier. Another high efficiency power amplifier is also provided. The amplifier includes a drive amplifier and latter power amplifier. The amplifier also includes a second multiplex control module, a fourth digital pre-distortion correction module and a second selection module.
