Book Synopsis Surface Acoustic Wave Filters by : David Morgan
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

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the report is to provide a unified and reasonably self-contained source of theoretical techniques for ideal Surface acoustic wave (SAW) bandpass filter design and analysis. Topics discussed include an introduction to sampling theory, transducer analysis from sampling weights, cosine squared-on-a-pedestal transducers, phase reversal transducers, Dolph-Chebyshev and Kaiser weighting for sharp-cutoff filters, optimum (equiripple) filter synthesis plus Butterworth and other no-null frequency response filters. In addition, periodic time and frequency responses are discussed. Synthesis of phase weighted bandpass filters are also considered in detail, as are second order and real life effects such as inaccurate apodization, inaccurate finger placement, electrode resistance effects, and phase distortion due to the finite gap between electrodes and dummy electrodes. In all cases, full computer program descriptions, listings and test runs are provided.

Available in PDF, EPUB and Kindle. Book excerpt: "The aim of this thesis was to extend previous work to SAW resonator based wideband bandpass filters on LiNbO3 substrates. In order to accomplish this aim, it was necessary to 1) apply coupling of modes (COM) theory 2) develop custom fabrication techniques for black LiNbO3 substrates 3) understand the critical issues in fabricating a wideband bandpass SAW filter. This thesis discusses the issues that must be addressed in order to achieve successful devices."--Abstract.
Book Synopsis Surface Acoustic Wave Band Elimination Filter. Phase 1 by : Michael B. King
Download or read book Surface Acoustic Wave Band Elimination Filter. Phase 1 written by Michael B. King and published by . This book was released on 1988 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: SAW devices are monolithic signal processing elements for frequencies between 10 MHz and 2000 MHz. SAW devices have many performance advantages which have resulted in wide ranging applications in military, commercial, and consumer systems. However, it has been generally recognized that SAW technology has been limited to bandpass filter functions and further that these filters typically have very high insertion loss (typically greater than 20 dB). This research program extends SAW technology to the bandstop filtering function with very low insertion loss and very high passband power handling capability. Prototypes of the SAW notch filter which are being developed under this program have already demonstrated insertion loss of less than 2dB. This notch filter could be very useful for eliminating specific interfering signals at a receiver front end without degrading sensitivity. The high performance notch filters described in this report are the result of research into methods for using inherently high Q of SAW devices for notch filters. (JHD).
Book Synopsis SURFACE ACOUSTIC WAVE NOTCH FILTER USING A PHASE-SHIFTING TECHNIQUE by : Thomas George Wear
Download or read book SURFACE ACOUSTIC WAVE NOTCH FILTER USING A PHASE-SHIFTING TECHNIQUE written by Thomas George Wear and published by . This book was released on 1974 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface acoustic wave (SAW) devices have been under development for about the past six years. These devices lend themselves to the construction of small, inexpensive delay lines and other wavelength-dependent devices because acoustical waves in solids propagate with a velocity roughly 100,000 times smaller than the speed of light. Surface acoustic wave devices already in commercial use include radar pulse compression filters, precisely shaped bandpass filters for color television, and other communication systems, low noise microwave generators, and various types of coding equipment.

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.
