RF Waveguide Termination, WR-62, UBR-140, 1.5 W, 11.9-18.0 GHz (Ku Band)

DLW62-U140-1R5 is a WR-62 waveguide termination with UBR-140 flange, designed to operate from 11.9 to 18.0 GHz with up to 1.5 W average input power at 25°C. It is intended for terminating unused waveguide ports, line ends and microwave test configurations in RF systems.

A waveguide termination absorbs RF energy and helps reduce unwanted reflections that can affect matching and measurement quality. This version is intended for low-power applications where very good matching performance is important, with a max VSWR of 1.03.
