Characteristics
A heat exchanger, and not a conventional multistage reflector, enforces a heat insulation at incoming/ outgoing sections of delay lines. Therefore, the length of normal conducting coaxial cables is dramatically shortened. And a signal distortion is greatly reduced.
*Liquid He continuously run through. That eliminates the use of liquid N2. Therefore the size of a unit becomes smaller and coaxial cables at lead sections are shortened. That leads to the improvement of a signal distortion.
*All products, including superconducting delay lines, normal conducting coaxial cables, and connectors, are designed for 40 GHz applications.
