Abstract

Band pass filters for microwave frequencies realized with thin film bulk acoustic wave resonators (FBAR) are a promising alternative to current dielectric or surface acoustic wave filters for use in mobile telecommunication applications. With equivalent performance FBAR filters are significantly smaller than dielectric filters and allow for a larger power Operation than SAW filters . In addition FBARs offer the possibility of on-chip integration which will result in substantial volume and cost reduction. First part of the thesis consists of an overview of different types of resonators and their advantages and disadvantages, followed which the design of film bulk acoustic wave resonator (FBAR) and its characterization . Second part of thesis consists of the design of ladder filter from the designed series and shunt resonators and its characterization.
