Abstract
The paper is dedicated to improving the frequency response of FBAR filters by replacing some of the single FBARs with two resonators connected in parallel. The method is applied for the basic lattice filter architecture and its modification with twice fewer number of FBARs. The conditions that must satisfy the resonator parameters are derived by theoretical considerations and computer simulations.
