A series of RF Rotary Joints claimed to be compact in design, with VSWR, low insertion loss and minimal variation, have been released by Fairview Microwave. The series includes single-channel/single-axis and single-channel/multi-axis RF Rotary Joints, with operating frequency ranging from 0 to 18GHz depending on the model.
The 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 single-channel/multi-axis rotary joints includes one SMA male to female unit, one SMA male to male unit and one SMA female to female unit. Suitable applications include commercial and military radar, land-mobile-radio communications and anti-missile defence applications.
“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”, says Greg Arnold, Technical Sales Manager, Fairview Microwave. “Our new rotary joints and multi-axis ‘swivels’ can be used to accommodate linear and rotational motion while a system is under test.”
