    Rotary joint

    Rotary joint is a connected device used to realize RF signal transmission between two relative rotating mechanisms, which is mainly used for continuous rotating platform to keep RF signal continuous transmission to fixed platform in the process of 360° infinite continuous rotation.

    Product features are as follows:

    1. Small size, even small space can be installed.
    2. Strong versatility, both ends are standard RF coaxial connectors, and the coaxial cable of the same type of RF connector is directly matched.
    3. Wide, some support 1 DC~50GHz channel.
    4. Low loss, RF rotary joint usually uses high-performance antenna and transmission technology, can achieve low transmission loss, to ensure the transmission quality and stability of the RF signal, can be error-free transmission of high rate high-frequency (coaxial RF) signals.
    5. Multi-channel transmission: RF rotary joint can support multi-channel signal transmission, allowing multiple RF signals to be transmitted at the same time, providing greater flexibility and functionality.
    6. Wireless transmission: Radio frequency rotary joint through wireless transmission technology, you can transmit radio frequency signals in rotating motion, such as radio frequency signals, wireless network signals. This technology can avoid the limitations of traditional wired connections and provide more flexible wiring and use.

    The main applications are as follows:

    1. Robot technology: RF rotary joint can be used in the joint connection part of the robot to realize the rotation, movement and wireless communication of the robot.
    2. Rotating equipment: RF rotary joint is suitable for rotating equipment, such as camera head, rotating display, rotating billboard, etc., to achieve wireless signal transmission.
    3. Aircraft and spacecraft: RF rotary joints are also widely used in drones, aircraft and spacecraft, and can achieve data transmission, signal reception and power supply functions.

    Qualwave Inc. provides DC~50GHz high frequency rotary joint, can support single channel or multi-channel high frequency transmission, small phase fluctuation, insertion loss and voltage standing wave ratio index is superior, standard SMA, 2.4mm, 2.92mm and other connectors, suitable for satellite, radar and other fields.
