CAD Tools for the Design and Analysis of Surface Acoustic Wave Chirp Devices

Abstract

This thesis describes the principles involved and develops the software necessary to design and analyze any of a number of types of surface acoustic wave chirp filters. The analysis is based on a circuit model approach which requires the chirp transducer to be transformed into an array of smaller uniformly spaced electrodes. Each of these smaller electrodes represent a node of the circuit, and capacitors are connected between nodes. The circuit model approach is used with a modification that has been made in the way the capacitor values are calculated to take into account variations in overlap of electrodes. Three chirp devices were designed at UCF and fabricated at SAWTEK Inc. The transfer function, acoustic conductance, and group delays of the devices showed good agreement between the Computer Aided Design (CAD) predictions, theory, and experimental measurements.
