Quartz crystal filters are the optimum choice where the application requires selective narrow band filtering at HF and VHF frequencies. Because of the extremely high Q of quartz …

 — The first use of quartz crystals as filter elements was suggested by Waiter Cady in 1922 in his paper "The Piezo-Electric Resonator", although in the initial conception a single crystal only was used as a very narrow bandwidth coupling element. The use of multiple crystals in ladder and lattice configurations was proposed in the late 1920's and …

The Q's of such quartz crystal resonators range from 25,000 to 150,000! Another advantage is that a small temperature coefficient can be obtained for quartz crystals. This is useful so that the resonant ... These quartz crystals can be modeled as RLC filters in electrical circuits: V s X R s R +-V o Quartz crystal

What is a crystal filter? Definition of a Monolithic Crystal Filter: A monolithic (Greek: one stone) crystal filter has 2 sets of electrodes deposited on the same quartz disc. This forms 2 resonators with acoustic (mechanical) coupling between them. If the acoustic coupling is correct a filter response will be achieved.

The X-cut crystal has the lowest capacitance ratio (C0/C1 = 125) of all quartz crystal types making it very attractive for filter use. One problem with this crystal design is a strong coupling to a shear mode at a frequency approximately 40% …

The 7D series crystal filter is an electronic filter that uses our high-performance quartz crystals as its resonators. Due to the exceptionally stable physical and chemical properties of our quartz crystals, this selective filter possesses a very high Q factor which is usually over 10,000. Feature 1.

What Is a Crystal Filter? Crystal filters are filters that use quartz crystals. Crystal filters are mainly used as band-pass filters to extract the required frequency components. Crystal filters are effectively used to selectively extract frequencies because quartz crystals have high Q and steep passband characteristics.
