Flexlines
The performance of semi-rigid coax with a fraction the thermal load, footprint, and cost
Maybell partnered with top research institutions to develop a series of ultra-high-density RF ribbon cables for quantum applications.
The Flexlines’ geometry eases thermalization, lowering the thermal noise of the delivered signal. The small cross section and soft traces transmit dramatically less vibration, facilitating a more mechanically isolated sample.

Available in NbTi-NbTi, CuNi-CuNi, and SS-SS
PFA-coated conductors, 100% metal ground plane
Much more durable than traditional semi-rigid coaxs
Physically flexible to reduce vibrational load
Why the Flexlines?
Scalable
40% the thermal load, 20% the footprint at 100% the performance; Flexlines allow you to cool more traces with less power.
Compact
compatible with existing RF components, Flexlines also have a growing ecosystem of native components
Affordable
Flexlines cost less per trace than semi-rigid coax of the same material

Alternative wiring
Semi-rigid coax
We offer traditional coaxial wiring options for customers seeking to upgrade an existing system. All our wiring systems provide years of hassle-free operation in the most demanding cryogenic environments.
Our wiring options include CuNi-CuNi, NbTi-Nb-Ti, SCuNi- CuNi, and SS- CuNi, impedance matched to 50 Ohm. Most standard connectorization and attenuation profiles can be satisfied.
DC wiring
Twisted pair wiring can be incorporated through either the primary wiring inserts, or optional low-volume passthroughs. For the lowest thermal load, ultra-fine unsheathed 38 gauge twisted pairs are available. Alternatively, lower gauge twisted pairs bundled in Kevlar sleeves provide unsurpassed durability for applications that require frequent modification or at higher temperature stages.
Both room temperature and low-temperature connectorized can be adjusted to match client specifications, and break-outs can be added at any flange, for flexible device installation.
Fiber optics
Maybell’s system can incorporate most commercially available fiber optics through a hermetic fiber bulkhead with either FC/PC or FC/APC connectors, offering extremely high flexibility regarding wavelength and polarization properties.
Optical feedthroughs are available for M10 and M12 sizes.
