Book excerpt: -BANDWIDTH PRODUCTS EXCEEDING 10,000, USING PASSIVE, UNGUIDED PROPAGATION. The report presents experimental results on a delay line having 1/2 millisecond delay and 5 MHz bandwidth. This is a helical SAW delay line on a Bi12GeO20 wrap-around crystal plate, operating at 50 MHz, which proves that practical two-port delay lines operating in the millisecond range are within the current technology. An analysis has been made of the problem of broadbanding the transducers for long delay lines of this kind, which involve different considerations than for standard short delay lines. A loss balancing criterion is developed, and computer results are presented which show the general design parameters for delay lines having time delays extending to one millisecond together with bandwidth extending to 60 MHz, using graded interdigital transducer arrays.

Download or read book Acoustic Surface Wave Diffraction and Beam Steering written by Thomas L. Szabo and published by . This book was released on 1973 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report contains a detailed description of diffraction in acoustic surface wave devices. This source of loss is highly important in the design and realization of bandpass filters, long time delay lines and other devices for electronic sensors and communications systems. A complete review of acoustic surface wave diffraction on anisotropic substrates is presented. Full experimental verification of theory is provided. Complete computer program listings and descriptions are provided. The limits of applicability of the parabolic velocity surface theory are quantitatively delineated. Universal diffraction loss design curves are given for all parabolic materials. A limitation in the use of the exact angular spectrum of waves theory occurs for materials having a power flow angle slope approximately - 1 unless the velocity surfaces are very accurately known. Both YZ LiNbO3 and 16-1/2 degree double rotated LiNbO3 fall in this category. Approximate diffraction loss design curves are given for YZ LiNbO3. A complete tabular summary of all important material properties affecting acoustic surface wave device design is included. (Author).
Download or read book Surface Wave Devices for Signal Processing written by D.P. Morgan and published by North Holland. This book was released on 1985 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent years have seen the emergence of a wide variety of electronic devices making use of surface acoustic waves in solids. This book focusses on the devices of greatest current interest and on the principles underlying them. An introductory survey is followed by chapters on acoustic wave fundamentals, electric excitation, transducers, multi-strip couplers and propagation effects. The interdigital transducer is emphasised since it is a key element in most devices. The remaining chapters - about half of the book - describe practical devices including delay lines, bandpass filters, chirp filters for pulse-compression radar (including reflective array compressors), convolvers and oscillators. For the main devices the text includes design principles, second-order effects, practical performance and, where appropriate, the role of the device in system applications. Some of the more mathematical details are relegated to Appendices, which include electrode interactions in transducers, sampling theory, the electrostatic element factor and the required relationships from Fourier analysis. A classified list of over 500 references is provided.The book will be of interest to engineers developing surface-wave devices, and to those using the devices in practical systems. It is also very suited for university courses or research work.

This book was released on 2012-12-02 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface Acoustic Wave Devices and Their Signal Processing Applications is a textbook that combines experiment and theory in assessing the signal processing applications of surface acoustic wave (SAW) devices. The operating principles of SAW devices are described from a circuit design viewpoint. This book is comprised of 18 chapters and begins with a historical background on surface acoustic waves and a discussion on the merits of SAW devices as well as their applications. The next chapter introduces the reader to the basics of acoustic waves and piezoelectricity, together with the effect of acoustic bulk waves on the performance of SAW filters. The principles of linear phase SAW filter design and equivalent circuit models for a SAW filter are then described. The remaining chapters focus on trade-offs in linear phase SAW filter design; compensation for second-order effects; harmonic SAW delay lines for gigahertz frequencies; and coding techniques using linear SAW transducers. The final chapter highlights Some other significant alternative design techniques and applications for SAW devices. This monograph will be suitable for engineering or physics students as well as engineers, scientists, and technical staff in industry who seek further information on SAW-based circuits, systems, and applications.
Download or read book Folded Path Surface Wave Delay Line written by Fred Y. Cho and published by . This book was released on 1972 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: This development has resulted in a 100-microsecond folded path acoustic surface wave delay line with a bandwidth greater than 50 MHz centered at 150 MHz. The total package, which includes gain to offset the insertion loss, weighs less than 10 ounces. The operating line has a dynamic range greater than 40 dB and the delay varies less than + or - 0.6 percent over the temperature range ( -50 to +70 degrees C). The delay is achieved by propagating the surface waves around the ends and on both the front and back surfaces of the Lithium Niobate substrate. Various materials, polishing and grinding techniques, and transducer configurations were evaluated to establish this design. A second technique for realizing folded path acoustic surface wave operation on one surface of the substrate has also been evaluated. This technique, which uses unconnected conductor lines deposited on the surface to fold the surface wave beam, operates over wide bandwidths and holds much promise for future applications. (Author).

Book excerpt: Surface acoustic wave (SAW) devices are recognized for their versatility and efficiency in controlling and processing electrical signals. This has resulted in a multitude of device concepts for a wide range of signal processing functions, such as delay lines, filters, resonators, pulse compressors, convolvers, and many more. As SAW technology has found its way into mass market products such as TV receivers, pagers, keyless entry systems and cellular phones, the production volume has risen to millions of devices produced every day. At the other end of the scale, these are specialized high performance signal processing SAW devices for satellite communication and military applications, such as radar and electronic warfare. This volume, together with Volume 1, presents an overview of recent advances in SAW technology, systems and applications by some of the foremost researchers in this exciting field.
