Title:
HIGH-BANDWIDTH LOAD-MODULATION POWER AMPLIFIER AND CORRESPONDING RADIO FREQUENCY FRONT-END MODULE
Document Type and Number:
WIPO Patent Application WO/2023/138602
Kind Code:
A1
Abstract:
Disclosed in the present invention are a high-bandwidth load-modulation power amplifier, comprising a main-path power amplifier, an auxiliary-path power amplifier, a quadrature coupler, a main-path radio frequency signal matching network, an auxiliary-path radio frequency signal matching network and an output combined-path radio frequency signal matching network. When an input of a radio frequency signal is received, the quadrature coupler divides the input radio frequency signal into two paths of radio frequency signals, which have a 90-degree phase difference therebetween, wherein the radio frequency signal, which has a +45-degree phase, enters the main-path power amplifier, and the radio frequency signal, which has the -45-degree phase, enters the auxiliary-path power amplifier; and the output combined-path radio frequency signal matching network synthesizes a main-path signal and an auxiliary-path signal and then outputs a radio frequency signal. Further provided in the present invention are a radio frequency front-end module comprising the load-modulation power amplifier, and a corresponding electronic device. The load-modulation power amplifier provided in the present invention has the beneficial effects of a high bandwidth, a high efficiency, a low loss, etc.
