Coaxial Rotary Joint

Introduction

Coaxial Rotary Joint is a connecting device used to realize RF signal transmission between two relative rotating mechanisms. It is mainly used to keep RF signal continuously transmitted to the fixed platform during 360 ° infinite continuous rotation of the continuous rotating platform.

Like all coaxial systems, the maximum operating frequency of the rotary joint is determined by the coaxial connector used at the rotary joint port. Therefore, a 2.92mm female coaxial connector can be used for the rotary joint with a maximum operating frequency of 18GHz, and a standard SMA connector can be used for the coaxial rotary joint with a maximum operating frequency of 6GHz.

Advantage

Coaxial Rotary Joint is more and more widely used because of its transmission frequency bandwidth, small size, strong versatility and other advantages. It is generally used in situations with small installation space, few demand loops (generally 1-3 circuits), and relatively low transmission frequency (generally below 20GHz). Generally, both ends of such rotary joints are standard RF coaxial connectors, such as SMA, N-type, BNC, 2.92mm, 3.5mm, etc., which are very convenient for direct connection with coaxial cables with the same type of RF connectors.

Features

The rotation joint is different from the conventional adapter in that it can rotate about the axis in the direction perpendicular to the wave propagation. This type of rotation joint can freely rotate 360 degrees while maintaining the transmission characteristics. This type of joint is essential for all application scenarios that require rotating functions, such as rotating antennas (aerial surveillance), missile guidance systems, and other rotating radar applications. If there is no rotation joint, the rotation part of the signal chain cannot be connected with the fixed part.

Application

The coaxial rotary joint is a series component that must be used to connect the static RF system with the rotary RF line. These rotary joints are used in military, aerospace and commercial applications, and are usually used in conjunction with rotary antennas and radars. Specifically, coaxial rotary joints are used for air traffic control, image transmission, medical/industrial and telecommunications control, and ground-based, shipborne and space-based radars.
