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
