OVEN-HEATED CRYSTAL RESONATOR AND OSCILLATOR ASSEMBLY

摘要

A crystal resonator assembly is described wherein a piezo-electric resonator (14) is mounted over a heat conducting substrate (28) and one or more heat generating elements (40) are located on the substrate. The heating elements provide heat both by conduction and radiation and by virtue of the use of a heat conducting substrate enable a uniform and efficient heating of the crystal resonator to a desired oven temperature.
