Title:
NOVEL BROADBAND DOHERTY RADIO FREQUENCY POWER AMPLIFIER
Document Type and Number:
WIPO Patent Application WO/2023/130843
Kind Code:
A1
Abstract:
The present invention relates to the technical field of electronics, and provides a novel broadband Doherty radio frequency (RF) power amplifier, comprising: a power divider, an input matching network, a driver amplifier network, a differential signal conversion network, a main power amplifier network, an auxiliary power amplifier network, and a folded power combining transformer network. The power divider is used for performing power distribution on an input signal and then outputting a first orthogonal signal RF+ and a second orthogonal signal RF-; the input matching network is separately connected to an output end of the power divider, and an output end of the input matching network is connected to the driver amplifier network; an output end of the driver amplifier network is connected to the differential signal conversion network; an output end of the differential signal conversion network is separately connected to the main power amplifier network and the auxiliary power amplifier network; the main power amplifier network and the auxiliary power amplifier network are in network connection to the folded power combining transformer. The Doherty power amplifier in the present invention has a compact structure, a small size, small insertion loss and a broad frequency band.
