Coaxial Rotary JointsCoaxial Rotary joints are needed wherever high frequency signals have to be transmitted between a fixed platform and a second platform in continuous rotation. Typical applications include traditional radar technology for air traffic control or anti-missile defence, medical engineering, V-Sat and SatCom technology as well as TV camera systems or cable drums that allow sensitive cables to be wound up without twisting them, thus increasing their reliability.Download PDF

AOOD coaxial rotary joints allow signal transmission in the frequency range from DC up to 20 GHz. Single channel , dual channel and multi-channel RF solutions are available. The special benefits of AOOD coaxial rotary joints include their compact design, excellent VSWR and low attenuation loss, low variation of transmission properties during rotation and high crosstalk attenuation between the individual channels over the whole frequency range.
