Tx/Rx isolation enhancement based on a novel balanced duplexer architecture

Summary form only given, as follows. Duplexers are essential circuit elements in virtually all Frequency Division Duplex (FDD) communication systems. Duplexers provide filtering functions for transmission and reception bands; moreover they provide isolation. In this work we present a novel duplexer architecture that provides increased isolation without increasing the constituting filters order. Among the advantages of this novel technique is the reduction of filter complexity and improved isolation bandwidth.
