Microwave Acoustic and Bulk Device Technique Studies.
Abstract
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.
