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.
RF Rotary Joints - HR Series
Available for custom, DC-4.5, DC-18, 14-14.5 Frequency Rate(GHz)
GRAND HR Series RF rotary joints are designed according to the skin effect of high frequency signals and the structure of coaxial cable. Support single or multi-channels to transfer DC~18GHz RF signals, also can be integrated electric and other signals. HF rotary joint high frequency signal use 50Ω characteristic impedance RF coaxial structure.
With almost 10 years experience of high frequency slip ring, RF slip ring. GRAND offer rotary joints with compact design, excellent VSWR, low insertion losse and minimal fluctuation.
Although GRAND offer modularized & standardized design for various application solutions as an original slip rings manufacturer. To create your most suitable RF rotary joint connector, please feel free to contact us.
