Product Spotlight
Microwave Techniques waveguide rotary joints are constructed with high power levels in mind. Double bearings and precision seals allow for reliable pressurization with dry air, nitrogen, or SF6 to increase the power carrying capacity. The design makes these rotary joints capable of transmitting extremely high power levels. The tight control of all machining tolerances minimizes the effects of rotation on the electrical performance. Most units are available and constructed in U-Style, L-Style and Inline Style configurations. These are serious rotary joints for serious applications.

More About Waveguide Rotary Joints
What are rotary joints?
A rotary joint is a waveguide component used to connect two different interfaces. They have the ability to rotate while still passing signals, with minimal losses. Our typical geometric configuration styles include: U, L, and Inline types.
In which applications are they used?
Waveguide rotary joints are used for transmitting high power microwave and RF signals. They are often used in air traffic control radar systems, as well as other applications in which a 360-degree rotation is necessary.
