DLW51-U180-100 is a WR-51 waveguide termination with UBR-180 flange, designed to operate from 14.5 to 22.0 GHz with up to 100 W average input power at 25°C and 1000 W peak power. It is intended for terminating unused waveguide ports, line ends and microwave test configurations in RF and high-frequency systems.

A waveguide termination absorbs RF energy and helps reduce unwanted reflections that can affect matching, measurement quality and overall system behavior. In this configuration, the aluminum heatsink supports applications where thermal management and higher power handling are important selection criteria.
