The Phoenix Company of Chicago, Inc.

SMA cables and HD PkZ microwave contacts, cables and housings provide a full dilution refrigerator system, from hermetic header through each level to interface with the quantum chip. HDQ18 microwave connections offer a complete board-level solution.

XMA Corporation

Designs and manufactures passive components such as attenuators, terminations, bulkheads, DC blocks, power dividers and couplers. XMA€™s cryogenic attenuators, terminations and bulkheads are used in quantum computing, aerospace exploration and more.

Other Suppliers:

ALLVAR

ALLVAR Alloys are the world’s first negative thermal expansion alloys. These materials passively shrink when heated and expand when cooled compensating for the CTE mismatch between other components. We make constant force-load washers and spacers for fasteners used in cryogenic assemblies. These washers expand while other materials contract in order to keep a consistent force-load on a bolt. We also manufacture custom components of material to meet specific designs. Want to learn more? As experts in these materials, we are happy to help determine if the material is a good fit for your application.

API Technologies (APITech)

Manufactures fixed coaxial attenuators, DC-40 GHz (SMA, SMPM and 2.92 mm), standard (0, 3, 6, 10 and 20 dB) and custom attenuation values, 50 ohms. Also provides Powerfilm SMT chip attenuators, DC-18 GHz, 0-20 dB, 50 ohms, alumina substrate, 4 mK to 150 Celsius.
