Title

Evolution Of The Saw Transducer For Communication Systems

Abstract

This paper will review the evolution of SAW transducer technology for communication systems. Applications of TV sets, radars, satellite communications, mobile phones and a wealth of others have driven a diversity of transducer embodiments. Some of the diverse sets of transducers include: bidirectional, multi-phase unidirectional, single phase unidirectional, chirped, coded, slanted, resonant and others. Scientists and engineers continually push the limits on materials, device design and manufacturing, leading to lower loss, broader bandwidths, smaller size and lower cost devices. Over the past 3 decades competing technologies have rose to challenge SAW devices, such as CCDs, ceramic filters, film bulk wave devices, MEMs and others, however, SAW transducer technology has been remarkably robust in adapting to system needs and continues to fill vital positions in communication transceivers. Connections between past military requirements, commercial communication systems and current consumer applications have driven the transducer technology in varied directions culminating in today's diverse, application specific devices. This paper will take an historical view of the SAW transducer's diverse embodiments, practical implementations, and innovative problem solutions, through the eyes of the IEEE Ultrasonics, Ferroelectrics, and Frequency Control (UFFC) society publications. © 2004 IEEE.
