POWER AMPLIFIER, ASYMMETRIC DOHERTY POWER AMPLIFIER DEVICE AND BASE STATION

摘要

The embodiments of the present invention have disclosed a power amplifier, an asymmetric Doherty power amplifier device and a base station. In the embodiments of the present invention, different radio frequency power amplifier channels are integrated within a component to form a power amplifier, thus reducing the discreteness between the different radio frequency power amplifier channels in such a way that a test and a selection are performed during production, and avoiding the occurrence of a situation that performance can not be controlled as the component discreteness between the different radio frequency power amplifier channels can be only found during application in the prior art. Since the power amplifier is a single component, a lower discreteness can be guaranteed during application, which is helpful to improve the performance of the ADPA circuit.
