There are four kinds of RF-IF filter which may be defined. Each different kind rejects or accepts signals in a different way, and using the appropriate kind of RF filter it is possible to accept the required signals and reject the ones which aren't desired.The file can be downloaded
Before using the SAW Filter, do a good job of grounding to minimize the coupling between the input and output. Otherwise, this coupling will cause the amplitude and group delay of the device to fluctuate. Note that the wave frequency is f = 1/TThe file can be downloaded
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 file can be downloaded
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 file can be downloaded
