摘要：
A radio frequency filter system includes a first acoustic resonator (54, 56) for a first frequency and a second acoustic resonator (54, 56) for a second frequency. An acoustic reflector array (102, 152, 202) is coupled to an electrode of the first acoustic resonator (54, 56) and to an electrode of the second acoustic resonator(54, 56). The acoustic reflector array (102, 152, 202) includes a plurality of reflector layers (112, 152, 210). A first reflector layer (112, 152, 210) is operable to reflect a signal at substantially the first frequency. A second reflector layer (112, 152, 210) is operable to reflect a signal at substantially the second frequency.
