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

Book Synopsis VHF-UHF Passive Filter Synthesis Based on Acoustic Resonator Structures by : Melissa Sefton Dempsey
Download or read book VHF-UHF Passive Filter Synthesis Based on Acoustic Resonator Structures written by Melissa Sefton Dempsey and published by . This book was released on 2009 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This thesis presents a novel design method for approximating standard bandpass filter transfer functions using surface acoustic wave (SAW) technology. This method is based on standard circuit simulation and optimization tools to generate physical specifications for the fabrication of a SAW impedance element filter (IEF) network. The IEF topology is verified in the design of a narrowband bandpass filter composed of commercial quartz SAW resonators. The utility of the design method is further demonstrated for a wider bandwidth filterbased on custom resonators fabricated on a lithium niobate substrate. An optimum fit was obtained between the standard filter target response and the corresponding SAW IEF response. Comparisons made between the two networks show that by exploiting the high Q characteristics of SAW devices in an IEF configuration, smaller footprints and tighter filter tolerances are obtained."--Abstract.
Book Synopsis Impact of SAW Filters on RF Pulse Frequency Measurement by Double Detection by : Kenneth R. Laker
Download or read book Impact of SAW Filters on RF Pulse Frequency Measurement by Double Detection written by Kenneth R. Laker and published by . This book was released on 1975 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: When it is desired to measure the frequency of RF pulses to within a resolution comparable to the pulse spectral width, special techniques must be adopted. Double detection is such a method. The report presents a simplified mathematical model of the double detection frequency measurement technique. Both frequency and time domain (through the use of an FFT routine) responses of the two individual filters are considered along with the difference of the squares of the time domain responses. Good agreement between theory and experiment is shown. The model includes gating and thresholding and the effects of these parameters are investigated. A complete computer program description, listing, and test case are given. This model can be used to optimize the parameters of a double-detection system. Finally, the model has been used to evaluate the double detection performance of a variety of filter responses including Butterworth, flat exponential filter, brick wall, Kaiser truncated sinx/x, Hamming, and Gaussian.

Book Synopsis UHF Multilayer Acoustic Filter by : Alfred J. Bahr
Download or read book UHF Multilayer Acoustic Filter written by Alfred J. Bahr and published by . This book was released on 1968 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: The theoretical design of a multilayer acoustic filter is described. A prototype design that uses a minimum number of gold and aluminum films and cadmium sulphide input and output transducers is analyzed and is found to have a 3-dB bandwidth on the order of one percent and an insertion loss on the order of 20 dB. To overcome this insertion loss a transistor amplifier is added in series with the filter. Analysis of both field-effect and bipolar transistors shows that, if no external tuning or impedance matching is allowed, the bipolar transistor is superior. A method is described for measuring the change in amplitude of an acoustic wave as it is reflected from the end of a sapphire rod that is being coated by a metal film or films. The magnitude of the acoustic losses can be inferred from these data. It was found that at 575 MHz the acoustic Q of gold is on the order of 100, while that of aluminum is on the order of several hundred. The construction and testing of several multilayer acoustic filters is described. None of these filters exhibited the desired transmission response, but one of them showed indications that some coupling to acoustic waves was taking place. RF leakage was found to be a major problem in these devices. The construction of several multilayer acoustic transducers on sapphire delay lines is also discussed, wherein it was found that gold-aluminum bimetallic films alloy at relatively low temperatures.

Book Synopsis MSW Reflecting Array Filters by : John M. Owens
Download or read book MSW Reflecting Array Filters written by John M. Owens and published by . This book was released on 1983 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface Acoustic Wave (SAW) Reflective array filters (RAF's) which operate very effectively in the VHF/UHF range experience significant technical difficulties as the operating frequency is increased above 1 GHz and bandwidths greater than 300 MHz are required. In particular, operation above 3 GHz requires submicron device dimensions and corresponding propagation loss is high. Recently, it has been proposed and demonstrated that quasi-isotropic magnetostatic forward volume waves (MSFVW) propagating in liquid phase epitaxially grown. YIG films can be obliquely reflected by arrays similar to those used in SAW RAF's to provide bias field tunable, compact, nonrecursive transversal filter at microwave frequencies (1-20 GHz). This paper will describe the background and status of this new RAF technology based on MSFVW propagation in low linewidth thin film YIG. The propagation of MSFVW is nominally isotropic in the plane of the film, with a lowest order mode bandwidth of greater than 2 GHz with center frequency bias field tunable.
