Connectors
High Performance Connections With Minimal Footprints
The i/o chain features three points of interfacing:
-
Outside the fridge (between room temperature electronics / cables and Cri/oFlex®), for which multichannel coaxial SMA- and SMP blocks are available;
-
Inside the fridge between flex to anything (e.g. to go from the Ag- to the NbTi platform), for which our high density Tabbi/TM connectors are developed
-
Between the flex and the quantum device, for which multichannel coaxial SMA- and SMP blocks are available.
-
We have PCB to flex interfaces available upon inquiry.
Tabbi/TM Flex Connectors
To remove bulky interconnects, while still allowing for modularity in your cryogenic chain, we have developed a flex-to-flex interface to connect two open-ended 8-channel Crio/Flex® 3 cables. This ultra-high density microwave interconnect allows modular configuration of any Cri/oFlex® 3 i/o chain.
1.5 mm pitch
Characteristic impedance 50 Ohm
S11 below-15 dB @ 6 GHz
50x repeat connections
EL-FEXT below -52 dB @ 6 GHz
Contact Resistance <5 mOhm at 4 K
Coaxial Connectors
SMA connectors are available in 8 channel blocks. SMA connectors have long been the industry standard because of their sturdy nature and good microwave performance up to 18 GHz. The connector blocks are relatively large to allow tightening the connectors with a torque wrench.
