Millimeterwave super-low-loss delay lines

Model No. MRS02

The use of dielectric waveguides allows for ultra-low-loss experiments without radiating radio waves into space during research, development, and shipping tests of millimeter-wave radars and altimeters.

As a result, data is accurate and measurements can be performed in a short time.
The standard connection is a waveguide flange type, but a lens antenna type is also available, which enables measurement while the radar or other antenna is still attached.
