What is RF rotary joint?

RF rotary joint is the abbreviation of radio freqency, used to transmit radio frequency signals between rotor and stator parts in a rotary system. RF rotary joints can be divided into three types, coaxial rotary joints, waveguide rotary joints and waveguide to coaxial rotary joints. The possible applications range from radar antenna, military, air traffic control, space. It is often necessary to receive and send multiple frequency signals.
