摘要:
A filter and method of manufacturing a filter having a lattice arrangement that efficiently utilizes substrate space. An embodiment of the invention is directed to a filter having a plurality of resonators disposed on a substrate, each resonator comprising a first electrode and a second electrode disposed vertically adjacent such that an acoustic cavity of a piezoelectric material is formed between each first electrode and each second electrode of each resonator, the first and second electrodes of each resonator electrically isolated from each other via the piezoelectric material. In this manner, the filter is realized without having to use any vias. Additionally, the resonators may be of a shape that allows each to be disposed close together such that some sides of each of the resonators are parallel to each other. Thus, substrate space can be preserved even further.
