Get ready for March Meeting
Delft Circuits is introducing a full stack I/O for quantum computing, microwave drive and flux-bias lines for addressing qubits at ultra-low temperatures. Measurement wiring from room temperature down to the mK stage with integrated filtering is now possible. Filtering includes attenuators, low-pass and infrared filters, and superconducting flex.
No need to worry about the different hardware suppliers. With the Cri/oFlex technology, there is no need for additional filtering components for the measurement wiring. Reed more in the brochure.

Product overview
Overview of our flexible cryogenic i/o product range


Ultimate cryogenic flexibility
Ultra-flexible microwave i/o for scanning probe microscopes and other vibration sensitive instruments. The thinnest and the most flexible cryogenic RF cable allows you to transmit your signal while offering extreme vibrational decoupling.
- Up to 18 GHz
- < 4 μW/channel (3K - 0.7K)
- Up to 60 cm length
- Customizable connectors
- < 1 mm Bending radius
- Single channel
- UHV compatible


The new cryogenic microwave standard
Single channel microwave i/o for densely-packed sample spaces in the refrigerators. Simple installation, small form-factor and reduced thermal loads, allow an increased number of microwave lines in cryostats. This flexible cryogenic cable is a new standard.
- Up to 26,5 GHz
- < 8 μW/channel (3K - 0.7K)
- Up to 100 cm length
- Customizable connectors
- 2 mm Bending radius
- Single channel
- Ultra durable


Massively scalable cryogenic i/o
Massively scalable multi-channel flexible RF cable for refrigerators, optimized for quantum computing applications with built-in on-flex filtering for signal conditioning.
- Up to 10 GHz
- < 4 μW/channel (3K - 0.7K)
- Up to 130 cm length
- Customizable connectors
- 5 mm Bending radius
- 8 Parallel channels
- Integrated filters
