Download or read book Surface Acoustic Wave Filters written by David Morgan and published by Academic Press. This book was released on 2010-07-27 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface Acoustic Wave Filters gives the fundamental principles and device design techniques for surface acoustic wave filters. It covers the devices in widespread use today: bandpass and pulse compression filters, correlators and non-linear convolvers and resonators. The newest technologies for low bandpass filters are fully covered such as unidirectional transducers, resonators in impedance element filters, resonators in double-mode surface acoustic wave filters and transverse-coupled resonators using waveguides. The book covers the theory of acoustic wave physics, the piezoelectric effect, electrostatics at a surface, effective permittivity, piezoelectric SAW excitation and reception, and the SAW element factor. These are the main requirements for developing quasi-static theory, which gives a basis for the non-reflective transducers in transversal bandpass filters and interdigital pulse compression filters. It is also needed for the reflective transducers used in the newer devices. A thorough revision of a classic on surface acoustic wave filters first published in 1985 and still in print Uniquely combines easy-to-understand principles with practical design techniques for all the devices in widespread use today Complete coverage of all the latest devices which are key to mobile phones, TVs and radar systems Includes a new foreword by Sir Eric Albert Ash

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 Wideband Dispersive Surface Wave Filters written by H. M. Gerard and published by . This book was released on 1974 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of this program clearly demonstrate that broadband, large dispersion reflective array filters can be readily implemented, noniteratively, based on a simple design model. With careful control on filter fabrication and measurement, corrections in the phase response can be introduced to achieve a high sidelobe suppression capability. To the small extent that 'ideal' performance was not achieved in the present device, the inadequacies proved to be associated with the transducer rather than reflective grating limitations. From the excellent agreement between theory and measurement, it is safe to conclude that it is quite feasible to achieve required transducer equalization through non-iterative compensations in the reflective grating design.
Download or read book Surface Wave Resonator and Bulk Wave Crystal Filters written by K. M. Lakin and published by . This book was released on 1979 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report details a 32 month research project on surface acoustic wave, SAW, two port resonator filters, phase weighted gratings for surface wave resonators, and the equivalent circuit modeling of a thin film stacked crystal bulk wave filter. The report details a new device configuration for coupled two port SAW resonators which would allow the coupling to occur only when the grating reflectors are in resonance and would offer little coupling when the resonator is out of the resonance condition. This configuration is composed of an interdigital electrode transducer, IDT, which is placed within the grating itself but is an IDT whose periodicity is an even multiple of the wavelength. The concept of a phase weighted grating is described for use in wide band resonators. This new concept is based upon the unique properties of gratings and the concept of a movable reflection plane. A simple equivalent circuit for the thin film stacked crystal filter is derived for the first time and results in a lumped element representation for this important device. (Author).

Download or read book The Development of Surface Wave Dispersive Filters for Use in a Multichannel Pulse Compression System written by W. M. Bridge and published by . This book was released on 1975 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The technology and understanding of acoustic surface wave devices has progressed to the point where they can be used to implement sophisticated processing schemes such as a parallel channel pulse compression filter. The report discusses the design, development and experimental verification of the surface wave dispersive networks necessary to build a 7-channel pulse compression filter with 700 MHz bandwidth and a TW product of 4900. These individual channel filters must be time contiguous with identical linear FM dispersive characteristics. A division synthesis technique is developed for the realization of these filters. The technique is specifically tailored for an acoustic surface wave implementation consisting of one apodized and one unapodized transducer. The resulting filters were quite reproducible and their general characteristics (spectrum shape, bandwidth, and dispersive delay) were essentially as desired.

Download or read book Experiments with Chirp Filtering of Surface Waves written by Leif Bruland and published by . This book was released on 1971 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: In connection with the application of linear chirp filters to dispersed surface wave trains recorded at LASA, Montana, a number of events from the SinoSoviet region have been examined in order to determine the predictability of the time of the maximum filter output. The group velocities thus obtained were compared with the group velocities determined by an analyst using ordinary dispersion analysis. On the basis of the scatter in group velocities found, 'arrival time windows' for surface waves from various regions are given. Dispersion analysis has shown that the assumption of a linear frequency variation in surface waves is not always satisfactory. Therefore, we have allowed for non-linear frequency variation in the chirp filters, and some applications of such filters are demonstrated. (Author).

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.
