WR-137 C-Band Flexible Waveguide Rigid Extension 01007714-01 Rev 2 Three 90°

WR-137 C-Band Flexible Waveguide Rigid Extension 01007714-01 Rev 2 Three 90°

This WR-137 C-Band flexible waveguide assembly combines a corrugated flexible section with a rigid extension arm and terminates in large-format flanges at both ends. Part number 01007714-01 Rev 2, it incorporates three 90-degree bends, allowing it to route microwave signals through tight angular changes within a system chassis or between components. The flexible section permits slight positional adjustment during installation, while the rigid arm provides a stable fixed run. Flanges at both ends are brass-faced with multiple bolt-hole patterns for secure mating.

Applications

WR-137 is a standard rectangular waveguide size used throughout C-band RF and microwave systems, covering the 5.85–8.2 GHz frequency range. Flexible waveguide assemblies like this one are used to interconnect fixed waveguide components — such as feeds, filters, amplifiers, or transmit/receive modules — where rigid waveguide runs cannot accommodate angular offsets or slight positional misalignment. The rigid extension arm provides a stable mounting interface, while the flexible corrugated section absorbs mechanical tolerances and vibration. This type of assembly is common in ground-based and airborne satellite communication systems, C-band radar installations, and microwave test setups where a direct rigid connection between two components is not practical. The large-format 85mm x 85mm rigid flange is characteristic of high-power waveguide interfaces used in transmitter and antenna feed assemblies.
