RF rotary joints
As an international leader in innovation, SPINNER is a reliable supplier of advanced RF rotary joints and components for radar and satellite systems. Applications include traditional radar technology for air traffic control and medical engineering, V-Sat and SatCom technology as well as TV cameras or for the usage in cable drums that ensure an anti-twist protected winding for sensitive cables and thus increase reliability.
Non-contacting rotary joints are based on coupling mechanisms such as capacitive, inductive, transmission line or transformer coupling. These extremely long-lived rotary joints are available as coaxial and waveguide units for frequency ranges up to 110 GHz. Non-contacting rotary joints are used for narrow band transmissions and additionally, with special coupling structures, two different frequency bands can be transmitted parallel within one module (e.g. X- and L-Band).
The inner and outer conductors of stator and rotor of contacting rotary joints are DC coupled. These rotary joints are used for broadband applications and allow signal transmission in the frequency range from DC up to 67 GHz. In some cases, specially designed slip rings can be used at lower frequencies (e.g.: low frequency data). Depending on the unit size such contacting systems can transmit signals from DC up to 120 MHz.
SPINNER offers the complete range of waveguide rotary joints up to 94 GHz to help its customers with outstanding solutions. The product line follows a common design philosophy that is characterized by excellent electrical and mechanical performance, allied to a highly reliable design. Although realized in a non-contacting design which guarantees a long lifetime of a minimum of 20 million revolutions, SPINNER’s waveguide rotary joints are characterized by large frequency bandwidth and high-power capability.
The interface style describes the orientation of both interfaces (rotor and stator) of a rotary joint.
• I-style: Both interfaces in line with the rotational axis.
• U-style: Both interfaces perpendicular to the rotational axis.
• L-style: Special arrangement of interface orientation, one interface is perpendicular to the rotational axis, the other interface is in line with the rotating axis.
SPINNER RF components meet highest standards
SPINNER applies extremely high standards with regard to quality, engineering, materials and manufacturing e.g. DIN EN ISO 9001 – Quality Management, DIN EN ISO 14001 – Environmental Management and ISO 50001:2011 – Energy Management. This enables us to offer RF rotary joints with the best possible performance, even under the harshest environmental conditions.
