SURFACE ACOUSTIC WAVE DEVICE Russian patent published in 2007 - IPC H03H9/02 H03H9/145 H03H9/25 H03H9/42 H03H9/64 H03H9/68 H03H9/72 H03H9/76 

FIELD: radio electronics; acousto-electronic devices for processing surface acoustic wave signals.

SUBSTANCE: proposed device has piezoelectric acoustic line whose effective surface mounts input and output interdigital transducers. Device also has additional components such as reflectors with short-circuited electrodes and/or shielding structures. Internal region of bus abutting against active region is completely plated with metal. Intermediate region of bus is made in the form of periodically disposed non-metal-plated windows. External region of bus is completely plated with metal and its width is chosen basing on provision for minimizing resistance of bus as a whole.

EFFECT: reducing device aperture by two or three times which accordingly reduces size of piezoelectric acoustic line.
