Request InfoDesign & Manufacturing Capabilities
Every component is constructed from verified non-magnetic materials to prevent flux noise and qubit decoherence. Gold-plated OFHC copper and BeCu standard throughout.
Components are designed for effective heat sinking into cryostat cold plates. Proper thermalization ensures stable operation and prevents thermal load on the mixing chamber stage.
All components are characterized at cryogenic operating temperature. Measured data for attenuation, return loss, and insertion loss from 300K down to base temperature.
Custom attenuation values, connector types, cable lengths, and mounting configurations. Ganged attenuator blocks and bulkhead-mount options for dense cryostat wiring.
Proprietary thin-film resistor technology maintains precise attenuation values across the full temperature range. No resistance drift, no open circuits at cryogenic temperatures.
Full cryostat RF wiring packages including attenuators, cables, adapters, and mounting hardware for each thermal stage of your dilution refrigerator.
