Product details
The 646477-7 from TE Connectivity AMP Connectors delivers breakthrough performance in Backplane Connectors - Housings for quantum computing applications. This cryogenic-ready interconnect system maintains signal integrity at temperatures approaching absolute zero while addressing the unique challenges of qubit control and measurement systems.Featuring Shroud for Male Pins technology, this solution provides <0.1dB insertion loss at 4K temperatures with minimal thermal loading in dilution refrigerator environments.The Hard Metric, Type E design incorporates superconducting materials that maintain <1m contact resistance at cryogenic temperatures for Josephson junction arrays.With 250 filtered signal paths, this interconnect supports parallel qubit control with minimal crosstalk in 50+ qubit processors.The 0.079" (2.00mm) quantum-grade pitch spacing minimizes parasitic capacitance (<0.1pF) critical for preserving qubit coherence times in superconducting circuits.The 8 row configuration enables efficient routing of microwave control lines while maintaining 50 impedance in 3D quantum processor packaging.Designed for Through Hole installation, this connector features zero-thermal-expansion materials that prevent microphonic effects in sensitive quantum measurement systems.The Gray housing material exhibits negligible outgassing properties while providing visual contrast for optical qubit alignment systems.
