Stable Coaxial Rotary Joint For Radar, Medical Equipments And Satellite Communication With Low Insertion Loss
RF Rotary Joint
RF rotary joints are electromechanical devices designed to transmit RF signals between a fixed platform and a rotating platform. They are essential components in various high-performance systems, including high-definition camera systems, defense radar systems, and satellite communications (SATCOM).
Panlink RF rotary joints are engineered with a compact design, ensuring low insertion loss, excellent voltage standing wave ratio (VSWR), minimal fluctuation of electrical characteristics, and high crosstalk attenuation across all channels and frequencies.
Our product range includes a variety of RF rotary joints to meet diverse application needs:
