Fast Warmup Quartz Reference Oscillator.

Abstract

FAST WARMUP QUARTZ OSCILLATOR FOR USE IN PLANNED TACTICAL COMMUNICATION EQUIPMENT. The report includes design, fabrication, and performance details of such a device. Electrical, thermal mechanical, and microelectronic design criteria are given in sufficient detail to allow trade-offs with respect to performance goals. To keep the size of this stable 5 MHz oscillator within one cubic inch, microelectronic techniques are employed. The resonator is held at its upper turn point and is enclosed in a specially designed isothermal enclosure. The enclosure is held at a constant uniform temperature by a proportional temperature control circuit so that the enclosure is the oven for the resonator. Located on top of the enclosure, and maintained at a constant temperature, are the oscillator, heating transistors, the temperature controller for the enclosure, and a second control circuit.
