Innovative power distributed amplifier using the Wilkinson combiner

A topology of a power-distributed amplifier, improved by the insertion of an input Wilkinson divider and an output Wilkinson combiner, is presented. The advantages of the new configuration, in small signal and power performance, are demonstrated by comparison with a conventional configuration, for wide-band power applications. The opportunity to use more than two FETs makes the new configuration attractive and enables one to overcome the limitations of the typical binary power configurations
