PEM FOR FILTERS, UPPER SIDEBAND, (1.75 MC.) QUARTZ CRYSTALS TYPE EL-FR (X-1).

Abstract

The type III filter, a 12 crystal, equal motional capacitance design, were analyzed to determine the effects of crystal and coil losses. Two filters were constructed and the test results presented. Crystal designs were evaluated to determine the best techniques for the present application. The most desirable design, using elliptically beveled blanks, was finalized and evaluated.
