PEM FOR FILTERS, UPPER SIDEBAND (1.75 MC) QUARTZ CRYSTALS TYPE EL-FR(X-1).
Abstract
The measured response characteristics of five Type I (18 crystal, equal motional capacitance design) and five Type III (12 crystal, equal motional capacitance design) filters are given and discussed. Difficulties with temperature compensation of the Type III filters would require considerable engineering to perfect this design, so subsequent effort will be concentrated on the Type I design.
