Millimeterwave super-low-loss delay lines

Millimeterwave super-low-loss delay lines employ a dielectric material waveguide. Investigations, developments, and pre-shipment final tests of millimeterwave radars and altimeters can be conducted with super-low loss without emitting signals into air. This method increases accuracy of measured data. And measurements can be done promptly.
A waveguide tube flange type is the standard connector. A lens antenna type, which enables measurements while radar/ antenna are attached, is also available.
