Product details
Amphenol ICC (Commercial Products)'s L777HRD78P pioneers new D-Sub, D-Shaped Connectors - Housings solutions for quantum computing applications, engineered to maintain signal purity at cryogenic temperatures. This ultra-low noise D-Sub connector enables reliable qubit control signal transmission in superconducting environments down to 4K.Utilizing D-Sub, High Density architecture, the connector achieves 60% reduction in thermal conductivity compared to standard designs while maintaining mechanical stability.The Plug for Male Contacts interface employs superconducting materials that maintain <0.1m contact resistance at cryogenic temperatures for precise qubit control.Designed with 78 channels, the configuration supports 128-qubit systems with individual bias and readout lines in compact form factor.Special 4 row spacing prevents crosstalk between adjacent microwave control lines (<-40dB isolation at 10GHz).The 5 (DD, D) High Density incorporates thermal break technology that reduces heat leak to <10 W while maintaining vacuum integrity.Featuring Signal contacts with niobium-titanium alloy cores that maintain superconductivity in strong magnetic fields up to 16T.Optimized for Free Hanging (In-Line) installation, the connector includes non-magnetic fasteners that prevent interference with sensitive quantum measurements.The Housing/Shell (Unthreaded) design implements indium seals that maintain ultra-high vacuum (UHV) compatibility down to 10^-9 Torr.Incorporating Grounding Indents, the design implements superconducting RF filters that suppress noise above 20dB in the 4-8GHz quantum control band.Constructed with Steel, Tin Plated, the housing demonstrates negligible outgassing rates (<10^-12 Torr L/s cm ) for clean vacuum environments.Precision 100µin (2.54µm) plating ensures consistent thermal contraction matching to prevent microphonic effects during cooldown.
