Product Description
Narda-ATM 112-745-6 High Power Rectangular Waveguide Termination – WR-112, 7.05-10.0 GHz, 850W Average Power
This used Narda-ATM 112-745-6 is a high-power rectangular waveguide termination (also known as a waveguide load) designed to absorb RF energy and provide a matched impedance at the end of a transmission line. These components are essential for eliminating reflections in high-power microwave systems, protecting sensitive equipment from back-reflected power, and terminating unused ports.
Narda-ATM (formerly part of L3Harris, now operating as an independent entity with Narda-MITEQ) is a leading manufacturer of high-quality RF and microwave components for military, aerospace, and telecommunications applications .

About WR-112 Waveguide
WR-112 waveguide operates in the X-band frequency range (7.05 to 10.0 GHz). This band is commonly used for:
-
Radar systems – Weather radar, marine radar, and military fire-control radar
-
Satellite communications – Ground station equipment
-
Telecommunications – Point-to-point microwave links
-
Test and measurement – High-power RF testing
Waveguide terminations are critical components in these systems, absorbing unused power and preventing reflections that could damage transmitters or degrade system performance.
