Abstract
The present disclosure relates to a radio frequency power amplifier system () comprising a first () and a second input port (). The radio frequency power amplifier system () comprises a main amplifier () having an input () and an output () and a first () and a second auxiliary amplifier () having respective inputs () and outputs (). The radio frequency power amplifier system () comprises an internal load () connected to the output () of the first auxiliary amplifier (), a feedback network () having an input end () connected to the output () of the first auxiliary amplifier () and an output end () connected to the input () of the first auxiliary amplifier (). The radio frequency power amplifier system () also comprises a feedforward amplifier () having an input () and an output (). The inputs () of the main amplifier and the auxiliary amplifiers are interconnected with the first input port () at a common input node (), the output () of the second auxiliary amplifier () and the second input port () are interconnected with the input () of the feedforward amplifier () at a common node () and the outputs () of the feedforward amplifier () and the main amplifier () are interconnected at a common output node (). The main amplifier () is a replica of the first auxiliary amplifier () with an increased gain and the second auxiliary amplifier () is a replica of the first auxiliary amplifier ().
