Wideband electromagnetic interference filtering power divider with a wide stopband using the genetic algorithm

This paper proposes a new design of an electromagnetic interference wideband filtering power divider (FPD) with wide stopband based on the genetic algorithm (GA). A set data structures is constructed by describing corresponding connection method between basic units and their electrical parameters in three-port design. Then, GA used to find appropriate topology parameters, including isolation resistances, meet FPD specifications optimizing structures. For validation, one prototype implemented. The results indicate that exhibits compact size, sharp roll-off, good in-band isolations.
