High-frequency rotary joints are used in continuous rotation devices to transmit high-frequency and high-speed signals between the stationary and rotating parts. They can transmit analog signals and high-speed digital signals at frequencies ranging from 500 MHz to 50 GHz. These slip rings feature a compact structure, stable performance, excellent shielding, strong anti-interference capabilities, and are easy to integrate into other equipment. This series is divided into two types: high-frequency slip rings and high-frequency hybrid slip rings that combine power transmission.
