ABSTRACT:
A surface acoustic wave filter has a Lithiumniobate substrate of parallelogram configuration, which is bonded to a header having similar acoustic impedance. The substrate has three transducers arranged along its long sides at particular spacings destined to suppress triple transit echoes. The short sides are oblique and surface portions adjacent thereto are covered by surface waves attenuating paddings. Two such filters are cascaded on the same header.
