The temperature dependence of quartz crystal resonator frequencies is determine principally by the crystallographic orientation of crystal blanks. as frequency requirements become more stringent, the required angle tolerances can become tighter than the typical capability of many production… More

The success of numerous weapons systems, now under active development, depends upon electronics capable of withstanding very high acceleration and mechanical shock. Most will use crystal oscillators. Applications include guided munitions, smartand penetrating weapons. For this program we are… More

"Electrical filters are critical elements in communications, navigation and radar systems. The steadily increasing use of bandwidth in communications systems and consequent increased usage of microwave frequencies has created a need for small, selectivefilters above 1 GHz. Conventional lumped… More

At the present state of the art it is not feasible to generate a signal directly at the microwave operating frequency having the required short-term or long-term stability The best is a high-performance crystal oscillator, usually realized as an ovenizedcrystal oscillator (OCXO). The OCXO forms the… More
