Small, lightweight, reliable, low cost acoustic surface wave delay lines are particularly useful in a variety of military applications including electronic sensing and communications. The purpose of the report is to provide detailed comprehensive procedures and theories for the optimum design of UHF and microwave frequency acoustic surface wave delay lines consisting of two identical, periodic, uniform width, interdigital transducers. The circuit model used to characterize device performance as a function of frequency includes a lossy tuning inductor, finite resistivity transducer fingers, and parasitic shunt capacitance. Surface wave propagation loss is also included. Modified author abstract
