    Abstract: An acoustic wave device comprises a piezoelectric substrate, interdigital transducer electrodes having an electrode pitch λ0, and first and second reflector gratings disposed on opposite respective sides of the interdigital transducer electrodes in a propagation direction of a main acoustic wave through the acoustic wave device, the first reflector grating having a different electrode pitch λ1 than an electrode pitch λ2 of the second reflector grating to suppress ripples in a conductance curve of the acoustic wave device.

    Abstract: A bridge combiner can be implemented as a coupling circuit that includes a common node and configured to couple the common node to a first group of filters through a first path and to couple the common node to a second group of one or more filters through a second path. The coupling circuit can include a resonator such that an impedance provided by each filter of the first group for a signal in each band of the second group results in the signal being sufficiently excluded from the first path, and such that an impedance provided by each filter of the second group for a signal in each band of the first group results in the signal being sufficiently excluded from the second path.

    Abstract: An architecture can include a first group of filters each configured to support a band such that a first frequency range covers the respective bands, and a second group of one or more filters each configured to support a band such that a second frequency range covers the respective one or more bands. Each filter of the first group can be configured to provide an impedance at or near a short circuit impedance for a signal in each band of the second group, and each filter of the second group can be configured to provide an impedance at or near a short circuit impedance for a signal in each band of the first group. The filters of the first and second groups can be implemented as one or more multiplexers. The architecture can further include a coupling circuit having a common node and configured to couple the common node to the one or more multiplexers through a first path and a second path. The coupling circuit can be further configured such that the impedance provided by each filter of the first group for the signal in each band of the second group results in the signal being sufficiently excluded from the first path, and such that the impedance provided by each filter of the second group for the signal in each band of the first group results in the signal being sufficiently excluded from the second path.

    Abstract: Acoustic wave filters operating at wider passband with enhanced frequency response are provided herein. In certain embodiments, an acoustic wave filter comprises an input port and an output port, a plurality of series resonators electrically connected in series between the input port and the output port, the plurality of series resonators including a first group of resonators and a second group of resonators, each resonator of the first group of resonators having a raised frame region, the second group of resonators including at least one resonator having its resonance frequency closest to one edge of a target passband that is closer to its anti-resonance frequency lacking any raised frame region such as to broaden a bandwidth of the target passband, and a plurality of shunt resonators each being electrically connected between respective series resonators and a ground.
