Abstract
Abstract A plug in module for providing a temperature contolled environment and a electromagnetic shield for electronic circuits contained therein. The electronic circuit is mounted within a metallic enclosure so that a low impedance path for thermal conduction is provided to heater and a temperature sensor mounted on the exterior of metallic enclosure. Coaxial connections are provided so that the metallic enclosure functions as an electromagnetic shield. A thermally insulating housing encloses the metallic shell, the heater, the the temperature sensor, and other electronic circuit components that require temperature regulation. An electrical connector provides ''''plug-in'''' connections to the circuit elements within the module.
