Flexible multi channel cable

Flexible multi-channel cabling solution for scalability in cryogenic i/o

Cri/oFlex®3 lines serve a wide range of applications. This product features our high line density Cri/oFlex® technology and is available for both the Ag- and the NbTi platform. The product comes in different lengths with our standard SMA or SMP connectors. On this product, no components are integrated. However, this can be done on request.

Delft Circuits have re-envisioned the cryogenic i/o chain: a single-shot solution for getting your microwave signals from room temperature directly down to milliKelvin using a flexible multi-channel cabling solution. As part of this effort, every component of our Cri/oFlex® 3 flagship product is designed for scalability. Key challenges include balancing the thermal and electrical characteristics, whilst maintaining the robustness of the system in terms of installation and use. The small volume and low thermal load greatly increase the number of signal lines that can be installed inside a dilution refrigerator. This makes a flexible multi-channel cable Cri/oFlex® 3 a truly scalable technology for cryogenic i/o.
