Tactical Miniature Crystal Oscillator.
Abstract
The report describes the further development of a fast warmup Tactical Miniature Crystal Oscillator (TMXO). The intended use for this TMXO is as a reference frequency source in advanced tactical communications systems and in time ordered navigational systems. The quartz resonator is enclosed in a special enclosure, maintained at a constant temperature equal to the upper turn point of the resonator. The top of the crystal enclosure is the bottom of the microcircuit enclosure. This enclosure contains the oscillator/amplifier circuitry, heater, temperature controller and fast warmup compensation network. Both enclosures are supported by a thermal insulator, and all enclosed in an evacuated outer case. Changes in the electrical, mechanical and thermal design are described, pertaining to the solution of the remaining problems. Electronic methods for achieving the fast warmup compensation are discussed.
