WR137 U Shaped E Plane Bend Waveguide

WR137 U Shaped E Plane Bend Waveguide for Antenna Feeder Systems

This product is a professional Waveguide Bend featuring a U shaped E plane design that provides two direction changes. The waveguide operates in the WR137 (BJ70) band covering C band frequencies. As a U Bend, it brings the signal path back to a parallel offset position after two 90 degree bends. This configuration is ideal for routing signals around obstacles or creating compact system layouts. The U shape allows significant space savings compared to using multiple individual bends. The construction uses aluminum material with conductive oxidation and paint coating for durability. The interface is FDP70 flange for standard connection to WR137 waveguide systems. Custom options including different offset distances are available upon request.

This U shaped E plane bend delivers solid electrical performance across its operating frequency band. The Voltage Standing Wave Ratio (VSWR) is rated at 1.2, which shows good impedance matching with low signal reflection. The insertion loss is very low, ensuring efficient signal transmission through the double bend configuration. The U shape provides a smooth transition that maintains signal integrity while creating a parallel offset between input and output ports. The large cavity cross section allows high continuous wave and peak power transmission without breakdown or arcing. The robust aluminum construction provides good mechanical strength and resists vibration and deformation. The conductive oxidation and paint coating provide protection against corrosion and environmental exposure.

One clear strength of this U Bend is its ability to create a parallel offset in a single compact component. It is widely used in radar transceiver assemblies, antenna feeder lines, and RF transmission links where signals need to be routed around obstacles or between different levels. Other applications include broadcast television transmitters, microwave communication base stations, electronic warfare equipment, anechoic chamber testing, industrial microwave systems, ground station RF feeder systems, vehicle mounted and airborne RF equipment, and complete waveguide network assembly. The U shape is especially valuable in crowded equipment racks where space is limited and multiple direction changes are required to navigate around other components.

In practical use, this Waveguide Bend handles professional RF transmission tasks very well. For radar systems, it routes signals around other components in the equipment rack. For test laboratories, it provides a compact way to create offset paths in measurement setups. For communication systems, it allows signals to be routed from one level to another while maintaining the same direction. The FDP70 flange mates securely with standard WR137 components. The aluminum construction keeps weight reasonable while providing good durability. The U shape design eliminates the need for two separate bends and a straight section, saving space and reducing potential failure points. It stands as a solid example of a well designed U shaped waveguide bend for reliable low loss RF transmission in antenna feeder and system assembly applications.
