Fairview Microwave Inc., a supplier of on-demand microwave and RF products, has introduced its latest line-up of single-channel/single-axis and single-channel/multi-axis RF rotary joints. According to the company, the devices can be used in cases where RF signals have to be transmitted between stationary and moving parts of a system, commonly used in commercial and military radar, land-mobile-radio communications and anti-missile defence applications.

The rotary joints boast a compact design, excellent VSWR, low insertion loss and minimal variation of RF performance during rotation. The operating frequency ranges from 0-18GHz depending on the model.

RF rotary joints

Fairview's latest release includes four single-channel/single-axis rotary joints that provide a solution for antenna characterisation applications such as measuring antenna patterns. This line of single-channel/single-axis rotary joints includes two SMA female units, one PCB to SMA female unit and one 3-hole flange to SMA female unit. The company also has three single-channel/multi-axis rotary joints, commonly referred to as swivels. This line includes SMA male to female, SMA male to male and SMA female to female configurations. These single-channel/multi-axis rotary joints are aimed at applications where linear and rotational movement may cause undue stress and strain on the coaxial cables and the connectors they mate to.

Fairview's family of RF rotary joints is available from stock and can ship the same-day ordered.
