Claim 10:
11. A method of filtering radio frequency signals, the method comprising: filtering a radio frequency signal with a first acoustic wave filter coupled to a common node, the first acoustic wave filter filters the radio frequency signal with at least a first plurality of surface acoustic wave resonators and a first series bulk acoustic wave resonator coupled between the first plurality of surface acoustic wave resonators and the common node; and
filtering the radio frequency signal with a second acoustic wave filter coupled to the common node, the second acoustic wave filter filters the radio frequency signal with a second plurality of surface acoustic wave resonators that are non-temperature compensated and at least a third plurality of acoustic wave resonators that are temperature compensated are coupled between the second plurality of surface acoustic wave resonators and the common node.
