Abstract
An ovenized oscillator has two ovens. One of the ovens is heated by a heater and the other is cooled by a thermoelectric module. The ovenized oscillator has an inner oven with an oscillator located inside. A thermoelectric heat pump cools the inner oven. An outer oven contains the inner oven and the thermoelectric heat pump. A heater heats the outer oven. The ovenized oscillator is operated with the inner oven temperature being lower than the outer oven temperature to improve component life and reduce crystal aging.
