Abstract
An innovative distributed amplifier topology based on an input and an output Lange coupler is presented. The different feeding of the input ports and the recombination of the output signals, in comparison to a conventional distributed amplifier topology, results in a remarkable improvement of the output power, power added efficiency and gain. Several design examples confirm the advantages of the proposed configuration over the conventional one.<>
