Surface acoustic wave device, filter device and method of producing the surface acoustic wave device
The Journal of the Acoustical Society of America, 2006A surface acoustic wave device includes a piezoelectric substrate on which resonators having comb-like electrodes are formed; and a silicon substrate that is directly bonded to the piezoelectric substrate and is less expansive than the piezoelectric substrate, a cavity being formed in the silicon substrate and being located below at least one of the ...

Surface-acoustic-wave devices for communications
Proceedings of the IEEE, 1976Surface-wave components have demonstrated performance capabilities in the VHF/UHF range which are available with no other filtering technique. The major advantages of the filters are their small size, high reliability, low cost, high Q, good reproducibility, temperature stability, wide dynamic range, and linear phase response, as well as special ...

Surface Acoustic Wave Slanted Device Technology
IEEE Transactions on Sonics and Ultrasonics, 1979Abmacr-The most common linear FM chirp surface acoustic wave devices used in radar employ the conventional in-line structure for the transducer. These devices have Fresnel ripple and interelectrode reflections in the time domain that, unless compensated for, will degrade the compressed pulse time sidelobes.

A HISTORY OF SURFACE ACOUSTIC WAVE DEVICES
International Journal of High Speed Electronics and Systems, 2000This paper gives a historical account of the development of Rayleigh-wave, or surface-acoustic-wave (SAW), devices for applications in electronics. The subject was spurred on initially by the requirements of pulse compression radar, and became a practical reality with the planar interdigital transducer, dating from 1965.

Surface acoustic wave devices and applications
Ultrasonics, 1973Abstract The fundamental principles of spread spectrum signal processing are reviewed and the application of surface wave devices to a number of spread spectrum link configurations are described. Serial processing spread spectrum links have been operating successfully for years providing jam and multipath resistance communications, low spectra ...
