Miniature delay line having low direct coupling |
摘要 |
In a miniaturized delay line constituted by a single crystal through which an ultrasonic beam passes and by two electroacoustic transducers, the direct coupling between the input and the output of the delay line is attenuated by means of a molded shielding element of araldite loaded with silver. The molded element is placed around the output transducer as well as the lead which connects the transducer to one of the connector-pins of the base of the casing containing the delay line.
