What is a RF Rotary Joint ?
The Rotary Joint or Rotary Union is the link between the stationary and movable parts of a radar or microwave communication system. It enables low/high frequency signals and low/high power energy to be transmitted between the antenna and ground components, with little or no distortion. Rotary Joints provide the ability to transfer signals ranging from DC to 50 GHz and power ranging from milliwatts to Megawatts.
A RF Rotary Joint often has several microwave channels on the same concentric axis. Slip Rings and azimuth position sensors, optical encoders or inductive discs and fluid joints can also be integrated into the assembly, creating a rotating subsystem.
A large part of the Rotary Joint is based on non-contact technology to ensure a longer life. When there is a need for extra wide band width and corresponding contacting designs, EVERAXIS utilizes only high grade materials and proven designs.
What are RF Rotary Joints used for ?
EVERAXIS Rotary Joints are the link between the rotary part and the stationary part of radar, satcom and Electronic warfare systems in high end complex systems.
They are installed in Naval, Aerospace, Air traffic control and land systems as well as in all climates.
The Rotary Union can be found in both military and civilian systems. It is designed to operate continuously in harsh environments, where extreme product reliability and performance are required.
