ULTRAMINIATURE QUARTZ CRYSTAL UNITS
Abstract
Ultraminiature quartz resonators meeting the minimum Q requirement of 10,000 were fabricated at frequencies from below 9 mc to above 150 mc. Quartz plates as small as .100 inch in diameter gave satisfactory results over most of this frequency range. Contouring was necessary below 25 mc, but plane-parallel plates proved satisfactory above this frequency. Both ceramic and glass enclosures were developed for these resonators. The overall volume of these enclosures was less than .002 cubic inches. Metal holders obtained from a commercial source were also used. These holders had a volume of approximately . 006 cubic inches.
