Not all types of Quartz Materials are naturally occurring. Some transparent quartz crystals can be treated with heat or gamma-irradiation to induce color without naturally occurring. The sensitivity to this treatment depends on the location of the quartz being mined.
The SAW Resonator and the acoustic table filter are elastic waves that are generated and propagated on the surface of the piezoelectric substrate material and whose amplitude rapidly decreases as the depth of the material of the substrate increases.
The SAW filter has a small size and is suitable for micro-sealing, good consistency, and no need to adjust.
The basic structure of the SAW filter is to fabricate two acoustic and electrical transducers on the polished surface of the substrate material with piezoelectric properties - the interdigital transducer.
The effective filtering frequency range of common interference filters is from several KHz to MHz, and the effective filtering frequency of RF interference filters is from several KHz to more than GHz.
Wafer refers to a silicon wafer used for silicon semiconductor integrated circuit fabrication. Because of its circular shape, it is called a wafer.
