RF Rotary Joints High Frequency RF Rotary Joint is applied in constant rotating devices. RF Rotary Joint transmits high frequency signal and high speed signal from stationary part to rotary part. This rotary joint is able to transfer analog signals and high-speed digital signals with frequencies up to 500MHz-50GHz. RF Rotary Joint is compact in structure, stable in performance with good shielding effect, and low interference. Besides, high frequency slip ring can be easily installed in other applications.
