Book Description
This final report summarizes the most important results of the Investigation of Shallow Bulk Acoustic Waves (SBAW) program. This program was conceived on the principle that SBAW technology could lead to devices that are superior to those presently available for frequency filtering and control. The primary objective was to establish whether this technology could provide devices that were as stable as the low frequency bulk wave resonators and yet operate at frequencies higher than the surface acoustic wave devices. The investigations have shown that SBAW devices can be built with excellent temperature stability, low spurious modes and at frequencies higher than those of SAW devices and bulk wave resonators.

Book Description
Shallow bulk acoustic wave propagation in piezoelectric crystals is considered from the standpoint of work reported to date. It is compared to bulk and surface acoustic waves as to properties and device potential. Singly and doubly rotated cuts are considered, as are piezoelectric transduction, energy trapping equivalent networks, as well as areas of future work such as new materials, other than quartz, and nonlinear effects.

Book Description
The objective of this program is to develop stable shallow bulk acoustic wave (SBAW) oscillators, stabilized directly at L through X band frequencies. This first annual report describes the technical progress of the program for the period of September 1981 to August 1982. The major activities for this period were the examination of system applications of SBAW oscillators, SBAW device investigation, device fabrication, and oscillator circuit design. The parameters studied in the SBAW device investigation were material aspects, metallization effect, transducer configuration, equivalent circuit, and harmonic operation. Device fabrication has concentrated on delay lines operating at frequencies from 3 to 5 GHz, and results have been obtained for device mounting and packaging. SBAW oscillator circuit designs have been developed and are in fabrication. Several systems have been identified in which the use of high frequency SBAW devices will greatly improve system performance. From the system study, it is clear that as more and more weapon systems move to millimeter wave, there will be an increasing requirement for stable, low noise frequency sources and precision test equipment. SBAW technology will provide the devices which will be needed to meet this challenge. (Author).

Book Description
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, there 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 2, presents an overview of recent advances in SAW technology, systems and applications by some of the foremost researchers in this exciting field.

Book Description
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.
