Abstract

A differential filter includes a first input, a second input, a first output, a second output, and a plurality of acoustic resonator elements. The plurality of acoustic resonator elements is connected to the first input, the second input, the first output and the second output. The acoustic resonator elements are arranged to form at least two of a lattice structure, a full ladder structure and a paired half ladder structure.
