Dielectric waveguide lines for millimeterwave
(Received Dupont Plunkett Awards)

Model No. MMT01

The transmission body part is made of dielectric, which enables flexibility and very low insertion loss for millimeterwave.
This is best suitable for heat cut-off and high voltage cut-off of between cryogenic (super low temperature) and room temperatures.
