Declarations under Rule 4.17: as to applicant's entitlement to apply for and be granted a patent (Rule 4.17(ii)) as to the applicant's entitlement to claim the priority of the earlier application (Rule 4.17(iii)) (54) Title: ACOUSTIC WAVE FILTER INCLUDING TWO TYPES OF ACOUSTIC WAVE RESONATORS (57) : Aspects of this disclosure relate to a multiplexer, such as a duplexer, a quadplexer, a hexaplexer, or the like. The mul- tiplexer includes acoustic wave filters coupled to a common node. 21\" A first acoustic wave filter of the acoustic wave filters includes acoustic wave resonators of a first type and a series acoustic wave 24\" resonator of a second type coupled between the acoustic wave res- onators of the first type and the common node. In some embod- iments, the acoustic wave resonators of the first type are surface acoustic wave resonators and the series acoustic wave resonator of the second type is a bulk acoustic wave resonator.
