Packaging and signal transfer hardware for cryogenically cooled RF receivers Navy SBIR FY2007.2 Sol No.: Navy SBIR FY2007.2 Topic No.: N07-150 Topic Title: Packaging and signal transfer hardware for cryogenically cooled RF receivers Proposal No.: N072-150-0122 Firm: S2 Corporation 2310 University Way Building 4-1 Bozeman, Montana 59715 Contact: Luke Mauritsen Phone: (406) 922-0334 Abstract: While cryogenics is an enabling component for many new technologies, the integration of components into cryocoolers is fraught with challenges that hinder system deployment and technology advancement. We propose an cryogenic packaging approach based on experience and novel concepts to provide vibration isolation, thermal stability, interfaces for signal transfer hardware (either RF or optical, or both), and connectivity to a variety of commercial 4K cryocoolers. The devices can be integrated into 19" rack mounts for both the 4K cryocooler and compressor, with reliable, convenient and efficient connections to temperature stages. During Phase I we plan to design and demonstrate the predicted performance. In Phase II we plan to build and test a prototype version of the systems. Benefits: Technologies that require a cryogenically cooled device will benefit from a cryo device interface because it provides a stable cryogenic environment, isolated from vibrations and temperature fluctuations while also providing reliable interfaces with temperature stages and cost-effective integration of the device and signal transfer hardware. Potential military and commercial applications are cryoelectronic RF systems, medical imaging, cryogenic holography, lab research, IR sensors, SQUID's. Return
