Abstract: Aspects of this disclosure relate to a multi-path filter for filtering a radio frequency signal. The multi-path filter includes a band pass section and an extractor section. The band pass section including a series acoustic wave resonator. The extractor section includes a second acoustic wave resonator and a phase shifter. The multi-path filter has a passband formed by at least a combined impedance response of the band pass section and the extractor section. The multi-path filter has a rejection band outside the passband that is formed by at least cancellation of impedance responses of the band pass section and the extractor section. Related multiplexers, radio frequency modules, radio frequency systems, wireless communication devices, and methods are disclosed.

Abstract: Aspects of this disclosure relate to a multi-path filter for filtering a radio frequency signal. The multi-path filter includes two signal paths from a node to an output port. The first signal path includes a series acoustic wave resonator. The second signal path includes a shunt acoustic wave resonator and a phase shifter. Related multiplexers, radio frequency modules, radio frequency systems, wireless communication devices, and methods are disclosed.
