A Waveguide Single Channel Rotary Joint is a device used to transfer microwave energy from a fixed line to a rotating line. This type of rotary joint is an electromechanical device whose radio frequency (RF) performance relies on strict electrical and mechanical design. There are three common types of rotary joints based on physical geometry: I-type, L-type, and U-type.
I-type rotary joint: two transmission arms are in line with the axis of rotation.
L-type rotary joint: one transmission arm is perpendicular to the axis of rotation.
U-type rotary joint: both transmission arms are perpendicular to the axis of rotation.
These rotary joints are widely used in systems that require rotating parts, such as radar antennas and satellite communication antennas, to ensure reliable transmission of signals at the rotating interface. In addition, single channel rotary joints are often used in systems with limited space because they are compact and suitable for smaller application scenarios.
If you have special needs, it is recommended to contact our sales engineers for a detailed discussion to select the rotary joint model and configuration that best suits your needs.
