Field replaceable nonmagnetic SMA and 2.92 mm connectors for quantum computing, with a bandwidth of 27 GHz for SMA and 40 GHz for 2.92 mm versions. Materials used are phosphor bronze, beryllium copper, Teflon (PTFE) and Ultem.
Standard and custom cryogen-free ADR cryostats, LTS and HTS foundry services, advanced LTS and HTS dc SQUID sensors, TES microcalorimeter and STJ X-ray detectors, PC-based SQUID readout electronics, bundled and woven-loom cryocables and Mr. SQUID.
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.
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 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.
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.
Specializes in RF/microwave connectors, cables and components supporting cryogenic, aerospace, defense, commercial air and industrial markets. The company stocks more than 20,000 products and offers custom cable assemblies built in its AS9120 facility.
The BOP High Power are true 4-quadrant programmable voltage and current power supplies, capable of both sourcing and sinking power. These bipolar power supplies pass smoothly through zero to provide ± voltage and ± current.
