Thermo-electric cooled oven controlled crystal oscillator |
摘要 |
The present invention is a stabilized oscillator system comprising an oven controlled crystal oscillator positioned inside an insulated housing. Within the insulated housing, there is a cold plate in thermal contact with the oven controlled crystal oscillator and a thermo-electric cooler in contact with the cold plate. A heat sink external to the insulated housing is in thermal contact with the thermo-electric cooler. The thermo-electric cooler pumps heat into or out of the oven controlled crystal oscillator through the cold plate and into or out of the heat sink. The thermo-electric cooler is controlled as part of a feedback loop which attempts to stabilize the output frequency of the oven controlled crystal oscillator.
