Abstract: Aspects of this disclosure relate to an acoustic wave filter that includes a first shunt acoustic wave resonator and a second shunt acoustic wave resonator configured such that current flowing through the second shunt acoustic wave resonator generates a magnetic field that at least partly cancels a magnetic field generated by current flowing through the first shunt acoustic wave resonator. For example, current flowing through the second shunt acoustic wave resonator can generate a magnetic field in an opposite direction than a magnetic field generated by current flowing through the first shunt acoustic wave resonator. In embodiments, the first shunt acoustic wave resonator can be on an opposite side of a series acoustic wave resonator than the second shunt acoustic wave resonator in physical layout. Related acoustic wave filter dies, multiplexers, radio frequency modules, radio frequency systems, wireless communication devices, and methods are disclosed.

Abstract: An acoustic filter assembly for operating at a target band including multiple spaced sub-target bands. The filter assembly includes a first filter that passes a first band and a second filter that passes a second band. The first filter and the second filter have a transition band between the first band and the second band that is wider than the spacing between the sub-target bands. An interface receives a control signal that controls the transition band to be shifted between a first position and a second position, such that an upper part of a lower sub-target band is covered by the first band in the first position, and a lower part of an upper sub-target band is covered by the second band in the second position.
