ABSTRACT:
A reflective array surface acoustic wave signal compressor or expander (RAC) has a piezoelectric substrate (LiNbO.sub.3) upon which is deposited an input transducer and an output transducer and etched therein a reflective grating. The RAC grating comprises reflective elements which includes a plurality of grooves having either uniform depths and lengths and preselected widths or uniform depths, lengths and widths for producing a flat pass band or a desired frequency characteristic. Yields are increased owing to the simplified fabrication process and costs decreased owing to batch fabrication made possible by the resulting simplified fabrication-process.
