Dielectric Waveguide Assembly for Millimeter Wave
Model No. MMT01
With its transmission part being made only of dielectrics, this dielectric waveguide assembly has characteristics of flexibility and extremely low insertion loss for millimeter waves.
It is suitable for insulation of high voltage, or between cryogenic temperature and room temperature.
