Book excerpt: This final report summarizes the results of a single one year study of the device physics aspects of the thin film bulk acoustic wave resonator. The study involved high Q trapped energy resonators, zinc diffusions in GaAs as a precursor to temperature coefficient studies, and refinements to the two dimensional numerical analysis modeling of microwave acoustic boundary value problems by the finite difference method. Keywords: Microwave acoustics, Thin film resonators, Bulk acoustic waves, Diffusion of Zn, and GaAs.

Book excerpt: The final report describes device research in both linear and nonlinear acoustic devices for signal processing. Wideband, monolithic surface-acoustic-wave convolvers have been developed, based on nonlinear interaction between surface acoustic waves and conduction electrons in zinc oxide film on sapphire structures, achieving new ranges of conversion efficiency. A high speed 8-bit analog-to-digital converter has been developed, using a heretofore unused property of linear surface acoustic wave delay lines, which has potential for multichannel parallel processing with large data throughput.

Download or read book Microwave Acoustic Device Research at Standard Telecommunications Laboratories written by H. J. Shaw and published by . This book was released on 1969 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simultaneous measurements have been made of electric field and acoustic flux distributions in propagating domains in CdS crystals. Electric field measurements used a standard probe, while acoustic intensity measurements were made with a laser probe utilizing Brillouin scattering. Acoustic frequencies in the range between approximately 2.5 GhZ and approximately 0.3 GhZ could be covered. It was found that substantial acoustic flux exists at frequencies far below the maximum small-signal gain frequency, and that there were substantial differences in the spatial distributions of electric and acoustic fields. Measurements are continuing to cover wider parameter ranges. Microwave two-port fixed acoustic delay lines have been developed for use in calibration of STC C-band FM radio altimeters. Acoustic delay lines are very well suited to this application, as delay, bandwidth, and insertion loss requirements are well within the range of such delay lines. Scaling of these delay lines for X-band radar application is being undertaken. (Author).

Book excerpt: In the previous report results on a ZnO on Si convolver were described, where a conversion efficiency of - 55 dBm was obtained. During the reporting period a new type of broadband matching network which makes it possible to increase the bandwidth of the interdigital transducers from 8 to 22 MHz were designed and tested. New types of diffusion layer transducers using p(+) elements laid down in Si were also tested; these can be switched on and off by incident light or by changing an applied dc potential. The work on the diffusion layer transducers to improve their efficiency is also continuing, and to use a new dc sputtering station to make more reproducible convolver devices is also intended. In the last report a new approach to analog/digital conversion was introduced. It operates by comparing a reference signal, having a linearly varying amplitude versus time, with the analog input signal whose amplitude is to be digitized. The reference signal is produced by passing an rf tone pulse through an interdigital acoustic wave transducer. The basic convolution property of the transducer results in the production of the required linearly varying ramp. An integrated circuit comparator and counter are used to produce the digital readout. During the reporting period a first experimental model has been constructed, utilizing a 50 MHz surface acoustic wave delay line, and using four-bit words, which has established the principle of the device.

Book excerpt: Information essential for the accurate design of advanced acoustic surface wave filters, signal processors, and other miniature low-cost reliable devices for use in communications and electronic sensing is given. Numerical data on surface wave velocity, electromechanical power flow angle, mechanical displacement, electric potential, and estimates of surface wave coupling to interdigital transducers are given for various orientations of the following surface wave substrate materials: Ba2NaNb5O15, Bi12GeO20, CdS, Diamond, Eu3Fe5O15, Gadolinium Gallium Garnet, GaAs, Germanium, InSb, InAs, PbS, LiNbO3, MgO, Quartz, Rutile, Sapphire, Silicon, Spinel, TeO2, YAG, YGaG, YIG, and ZnO. This present volume is intended to be used as a supplement to Volume 1A whenever accurate numerical data is required rather than the more convenient graphical information.
