Product overview

Overview of our flexible cryogenic i/o product range

Cri/oFlex® 1

Ultimate cryogenic flexibility

Cri/oFlex® 2

The new cryogenic microwave standard

Cri/oFlex® 3

Massively scalable cryogenic i/o

Broadband microwave cabling in cryogenic systems requires a special combination of thermal and microwave properties. Moreover typical cryogenic setups are very confined and lead to densely-packed situations, where the form factor and flexibility of the cabling is critical.

Our Cri/oFlex® technology aims to bring a dedicated microwave solution to the cryogenic environment. By using a unique combination of polyimide and silver, we are able to construct extremely thin stripline channels with impressive microwave performance and unparalleled flexibility. We are continuously upgrading our products to provide the optimal cryogenic microwave solution for your applications. Find out more about our flexible microwave cables below!

Cri/oFlex® - flexible microwave cabling for cryogenic i/o

Scalability is key

Experience the convenience of a monolithic microwave cryogenic cabling solution, from room temperature straight down to milliKelvin. Every part of Cri/oFlex® is designed to be scalable, from our microwave channels to thermal anchoring, and from our vacuum feedthrough to the connector blocks.

  • 8 parallel microwave channels with 2 mm pitch
  • No breakouts required between stages
  • Heat Load of < 125 μW per channel @ 4K – 40K

Integrate and conquer

Contrary to the old Roman saying, Delft Circuits is integrating all filtering components to overcome traditional microwave engineering challenges in cryogenics. Integration of components removes potential points-of-failure, increasing the robustness of your setup and reducing installation time. Our current filter library contains:

  • Low-pass filters
  • Band-pass filters
  • Eccosorb-type filters
