MULTIPLEXER WITH FILTER HAVING INCREASED REFLECTION CHARACTERISTIC

Abstract:

Aspects of this disclosure relate to a multiplexer that includes at least a first filter having a first passband and a second filter having a second passband. The first filter includes acoustic wave resonators coupled to a common node by a series inductor. The acoustic wave resonators start with a shunt acoustic resonator from the common node. The series inductor and the shunt acoustic resonator of the first filter are together arranged to increase a reflection coefficient of the first filter in the second passband.
