ABSTRACT:
An apparatus for processing surface acoustic waves includes input and output transducers mounted on a piezoelectric substrate so as to launch and receive acoustic waves, respectively. Two pairs of reflective arrays are positioned in the propagation path between the input and output transducers so as to provide an S-shaped propagation path in which the directions of propagation of the waves launched by the input transducer and received by the output transducer are essentially parallel.
