Document Type and Number:
WIPO Patent Application WO/2022/252875
Kind Code:
A1
Abstract:
A power amplifier, a signal processing method, a transmitter, and a base station device. The power amplifier comprises: a main path power amplification module (130, 230), configured to perform power amplification on a main path input signal to obtain a main path power amplification signal; a main path output matching module (140, 240), configured to adjust the main path power amplification signal to obtain a main path output signal; an auxiliary path power amplification module (150, 250), configured to perform power amplification on an auxiliary path input signal to obtain an auxiliary path power amplification signal; an auxiliary path output matching module (160, 260), configured to adjust the auxiliary path power amplification signal to obtain an auxiliary path output signal; and a combiner output matching module (280), configured to adjust an output signal of a combiner output end (270) to obtain a target output signal.
