Abstract
Acoustic filter devices and methods of making filter devices. An acoustic filter device includes a transversely-excited film bulk acoustic resonator (XBAR) including a plurality of sub-resonators and conductors to connect the plurality of sub-resonators in parallel between a first node and a second node. The conductors are configured such that a path length from the first node to the second node is effectively the same through each of the plurality of sub-resonators.
