Crystal filter - Wikipedia
A crystal filter is an electronic filter that uses quartz crystals for resonators. Quartz crystals are piezoelectric, so their mechanical characteristics can affect electronic circuits (see mechanical filter).
Quartz Crystal Filter: Bandpass Filter » Electronics …
When a quartz crystal filter is designed factors such as the input and output impedance as well as bandwidth, crystal Q and many other factors need to be taken into account. Some of the chief factors are obviously the bandwidth, shape fact, and ultimate cutoff.

The crystal filters supplied by KVG are mainly band-pass filters with Chebyshev-characteristic (theoretical ripple 0.1 dB). Depending on the selection in the stop-band range and the ripple in the pass-band range the filter design can be chosen between Chebyshev-design and Butterworth design (theoretical ripple 0 dB).
Quartz Crystal Band Pass Filters » Electronics Notes
Crystal filters are widely used in many applications including radio receivers as well as many other radio communications applications. The very high level of Q makes the quartz crystal resonators they use makes them ideal for use as the primary band pass RF filter …
Crystal Bandpass Filters - W0QE
16.09.2011 · Crystals (not crystal oscillators) are used with the resulting filter frequency usually a few kHz different than the number stamped on the crystal case. I have found that HC-49/U crystals usually have higher Qs than the smaller HC-49/US packages.

Quarz-Ladder-Filter konstruieren. Mit Schwingquarzen lassen sich steilflankige Bandfilter mit Filterbandbreiten realisieren, die für CW, SSB und AM geeignet sind. Am Beispiel eines AM-Filters mit 6 Quarzen und einer Zwischenfrequenz von 10 MHz möchte ich die Vorgehensweise kurz demonstrieren. Worauf es bei der Vorgehensweise ankommt: Für die Berechnung der Quarzladderfilter gibt es ...

Quarzfilter – Wikipedia
Schaltplan eines Quarzfilters mit vier Schwingquarzen (englisch crystal ladder filter). Die Parameter des Quarzfilters, wie seine Grenzfrequenz und Dämpfungswerte, werden durch die mechanischen Abmessungen des Quarzes und den Quarzschnitt bestimmt.
Online Calculator .:. Quartz Crystal Filter Design
Quartz Crystal Filter Design. Equivalent Circuit Determination of Quartz Crystals. Before we may design a crystal filter it is necessary to know the crystals data. Unfortunately this information is not in the datasheet - or we have no datasheet because the crystals were bought on a market some decades ago ... A quartz crystal and its equivalent circuit. As you may have guessed from the ...
