Acoustic Delay Line Fabrication.

Abstract

This report describes work performed at the Harry Diamond Laboratories to establish a viable production method for fabricating series-transducer delay lines. The devices considered in this report consist of a crystal delay medium with a series-connected matrix of zinc oxide transducers deposited on each end. This is a new concept (U. S. Patent 3,893,048) which eliminates the need for external electrical matching. Two basic fabrication approaches were tried successfully, and a combination of the two was finally adopted. A step-by-step processing section furnishes complete data regarding the materials, methods, and techniques employed, with sufficient detail to facilitate technology transfer. The devices fabricated operated typically in the bulk wave mode in the 3- to 4-GHz range and displayed through insertion losses of 30 to 50 dB for delays in the 0.5-ms region. Some life-time and ruggedness data also are included. (Author)
