for Information/Sources Sought Notice for providers of 110 GHz Cryogenic Coax Cables Notice ID: NB672030-26-00372 Sought Response Date 03/11/2026 6625—Electrical and Electronic Properties Measuring and Testing Instruments NAICS Code 334516 – Analytical Laboratory Instrument Manufacturing

BACKGROUND This is a notice to request information from industry to help the U.S. Department of Commerce, National Institute of Standards and Technology (NIST) determine the availability and capability of small businesses and other than small businesses to provide 110 GHz Cryogenic Coax Cables, that require low thermal conductance (stainless steel or CuNi) thin-diameter coaxial wiring connectorized with 1 mm (or similar) rf connectors. To include infrastructure to install this coax into an existing dilution refrigerator – i.e. a vacuum feedthrough and high thermal conductivity copper plates at each temperature stage. Suppliers will work with end-users to get exact dimensions and lengths. This notice is strictly to request information for market research purposes to help NIST determine the appropriate acquisition strategy for this requirement. This notice shall not be construed as a solicitation, an obligation, or commitment by the NIST. OVERVIEW The NIST has a need for 110GHz Cryogenic Coax Cables. See attached Specifications document. ANTICIPATED

PERIOD OF PERFORMANCE/DELIVERY NIST anticipates the 110 GHz Cryogenic Coax Cables with deliver 90 days after receipt of order (ARO). INFORMATION REQUESTED FROM INDUSTRY SOURCES: NIST invites industry sources to review this notice carefully and to familiarize themselves with the Specifications document. Thereafter, by the closing date of this notice, NIST encourages those sources to submit responses to [email protected].
