A Surface Acoustic Wave refers to the wave delivered with concentrated energy around the surface of a medium. The surface acoustic wave function element has the following merits: light, thin, short, and small attributes, high speed, and low power consumption. And, thus, applicability to the filters, and signal processing elements of telecommunications equipment is very high.

The SAW Filter is a device using surface acoustic wave. A characteristic of the filer is that it can be made small, since Q is high and wavelength is about 5-10 fold of the electromagnetic wave, due to the use of mechanical vibration. Moreover, motion is limited to solid surface, and the filtering function is possible with only the circuit that can control SAW on the surface.
