  • Acoustical wax on a surface wave device
    Patent number: 4470026
    Abstract: A surface acoustic wave (SAW) filter partially coated with an acoustical wax, such as one soluble in trichlorethylene, or with an epoxy paint dramatically improves the performance of the filter, especially with regard to the attenuation of out-of-band signals.The coating pattern may be initially empirically determined depending on the substrate and transducer configuration but once determined is readily amenable to known printing and stamping techniques.

  • Surface acoustic wave filter
    Patent number: 4450420
    Abstract: A surface acoustic wave filter comprises aluminum input and output transducers, an aluminum 3db coupler, an aluminum reflector, and a triangularly configured substrate constructed from lithium niobate. In a specific configuration the lengths of the sides of the substrate are equal to approximately 6.06, 9.25 and 11.05 millimeters respectively. The triangular configuration not only reduces the amount of substrate material required but also attenuates the degree of signal reflection encountered.
