Cryogenic (super-low temperature) and superconductive coaxial cables and components
|Semi-Rigid Cables for Cryogenic (Super Low Temperature) Applications|
|KEYCOM offers wide variety of superconducting semi-rigid coaxial cables for cryogenic applications,
shown below in Table 1, from which you can select based on such features as heat conductivity,
flexibility, insertion loss, permeability, or thickness to meet your specific requirements.
They are low in heat conductivity, minimizing inflow of the heat from the high-temperature end.
Operating frequency is DC-40GHz by default, but available up to 65GHz upon request.
The characteristic impedance is 50Ω.

|Superconducting Coaxial Cable Assembly with niobium conductor,
recognized by research institutions all over the world.
Operating frequency is DC - 40GHz by default, but available up tp 65GHz upon request.
Minimum bend radius: 70mm
|Superconducting Coaxial Cable Assemblies (0.085" type NbTi-NbTi Superconducting Coaxial Cables)|
Superconduction coxial cable for cryogenic and strong electromagnetic field, recognized by research institutions all over the world. Highly effective at thermal gradient below 4K.
|Dielectric Waveguide Assembly for Millimeter Wave|
|With its transmission part being made only of dielectrics, this dielectric waveguide assembly possesses flexibility and extremely low insertion loss for millimeter waves.
It is suitable for insulation of high voltage, or between cryogenic temperature and room temperature.

|Cryogenic Low Noise Amplifier|
KEYCOM’s cryogenic low noise amplifiers are designed and manufactured to perform at their peak levels at extreme low temperatures (below 74K).
|Cryogenic Millimeter-Wave / Microwave Test Fixtures and Calibration Kits|
|Test fixtures and correction kits specifically designed for use at ultralow temperatures for testing the performance of patterns between the edges of printed boards (edge type) and circuit testing inside the printed boards (probe type).
We aim for drastic reduction of the influence of thermal shrinkage as well as for the miniaturization and the reduction of the heat capacity of our devices. In addition, our product line includes products operating in the 1 μHz - 300 GHz (infrasonic / VHF / UHF / microwave / millimeter wave / super-high) frequency range.
|110~140GHz Oscillator Systems|
|KEYCOM offers a millimeter-wave oscillator with variable attenuator whose frequency range is mechanically variable between
110GHz and 140GHz. The output can be read with a power meter. *Please ask your KEYCOM representative for frequency ranges of your request.
|Compact and Ultra-Compact Attenuators (operable at ultra-low temperatures)|
|* Ultra-compact(φ=5.2 mm, length 15.5 mm).
* All cases, connectors, contacts and resistors are non-magnetic.
* Cryogenic-resistant with resistors made of a non-superconductive material.
* Male-female connectors.
