Aspects of this disclosure relate to acoustic wave filters that include different types of acoustic wave resonators for series resonators and shunt resonators. In certain embodiments, an acoustic filter component includes a first die including surface acoustic wave resonators and a second die including bulk acoustic wave resonators. An interdigital transducer electrode of a surface acoustic wave resonator can be a side of the first die. An electrode of a bulk acoustic wave resonator can be on a side of the second die facing the side of the first die with the interdigital transducer electrode thereon. An acoustic wave filter can include series resonators on one of the first and second die and shunt resonators on the other of the first and second die.
