Radio Frequency Rotary Coupler

A Radio Frequency Rotary Coupler is a device used in the field of electrical and electronic equipment components, specifically in the supply class of Antennas, Waveguides, and Related Equipment.

A rotary coupler is designed to transfer radio frequency signals between two rotating parts while maintaining a continuous electrical connection. It allows for the transmission of RF signals from a stationary source to a rotating component, such as an antenna or a rotating platform.

The coupler consists of two main parts: a stationary section and a rotating section. The stationary section is connected to the fixed RF source, while the rotating section is connected to the rotating component. The two sections are coupled together through a set of electrical contacts or brushes, which enable the transfer of RF signals while allowing for the rotation of the component.

The primary function of a radio frequency rotary coupler is to enable the transmission of RF signals without the need for physical wires or cables. This is particularly useful in applications where continuous rotation is required, such as radar systems, satellite communication systems, and rotating platforms for antennas.

In summary, a radio frequency rotary coupler is a specialized component used in electrical and electronic equipment to transfer RF signals between stationary and rotating parts, allowing for continuous rotation without the need for physical connections.
