Microwave and RF product supplier Fairview Microwave has released a new line of single channel/single-axis and single-channel/multi-axis RF rotary joints.
Fairview’s RF rotary joints are designed to be used wherever RF signals have to be transmitted between stationary and moving parts of a system, including commercial and military radar, land-mobile radio communications and anti-missile defense applications. Featuring operating frequency ranges from 0 to 18 GHz depending on the model, these rotary joints boast a compact design, excellent VSWR, low insertion loss, and minimal variation of RF performance during rotation.
The latest release includes four single-channel/single-axis rotary joints, which, according to the company, provide the perfect solution for antenna characterization 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.
Also available are 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 targeted to applications where linear and rotational movement may cause undue stress and strain on the coaxial cables and the connectors they mate to.
“Fairview’s RF rotary joints are an invaluable accessory for any antenna test range where cables can easily become twisted and damaged due to continual rotation,” Greg Arnold, technical sales manager at Fairview Microwave, said. “Our new rotary joints and multi-axis ‘swivels’ can be used to accommodate linear and rotational motion while a system is under test.”
