WebCrystal types such as the J, NT, E, DT, and CT were commonly used for filter applications and classified as low-frequency elements. In the 1950’s the demand for higher frequency filters increased dramatically with the development of new communications, radar, and navigation equipment. WebAug 13, 2024 · This crystal ladder filter calculator is a simple tool for dimensioning crystal bandpass filters composed by 2 to 8 identical quartz crystals and some capacitors. Quartzes are used in their fundamental mode (even if they are overtone) in their series resonance (even if they were designed for parallel mode operation).
