Abstract
Official abstract text for this publication.
A radio frequency system includes a first power splitter, a first push-pull power amplifier and a second push-pull power amplifier. The first power splitter is configured to receive a first radio frequency signal and generate a first output signal and a second output signal. The first push-pull power amplifier is configured to amplify the first output signal. The first push-pull power amplifier comprises a first set of transistors including at least two radio frequency power transistors and a first output transformer. The second push-pull power amplifier is configured to amplify the second output signal. The second push-pull power amplifier includes a second set of transistors including at least two radio frequency power transistors and a second output transformer. An output of the first transformer is galvanically and directly connected to an output of the second output transformer.
