Abstract
A hermetic electronic assembly incorporating cryogenically-cooled and air-cooled elements in an integrated assembly. A hermetic cryogenically-cooled enclosure is disposed in close physical proximity to one or more air-cooled circuit cards to minimize physical separation, thereby optimizing signal bandwidth and noise immunity. The air-cooled circuit cards, which generate substantial heat but do not require low operating temperatures, are thermally decoupled from the cryogenically-cooled elements to optimize cryo-cooler efficiency by reserving cooling capacity for the temperature-sensitive processor elements mounted within an evacuated hermetic enclosure. Thus, thermal isolation and physical/electrical proximity are preserved in the same package.
