Twistable and Seamless Flexible Waveguides

Pasternack’s new line of twistable and seamless flexible waveguides operating in the 5.85 GHz to 50 GHz range and covering 10 frequency bands from WR-137 to WR-22. Typical applications include DAS systems, base stations, antennas and test instrumentation.

Pasternack’s newly released line of flexible waveguides is made-up of 78 total models – 39 seamless and 39 twistable. All models operate in the same wide range of frequencies, are available in lengths of 6 to 36-inches and with UG-style square/round cover and CPR-style flanges.

The twistable models are able to twist in different directions, the twist flex material is wound, interlocking brass that allows it to slide on itself. These flexible waveguides provide VSWR as low as 1.05:1, insertion loss as low as 0.15 dB and max power as high as 1.5 kW.

The seamless models are made of a solid piece of brass that is pressed into shape. These flexible waveguides can be used in pressurized applications, deliver VSWR as low as 1.07:1, insertion loss as low as 0.06 dB and max power as high as 5 kW.

“Pasternack’s new family of flexible waveguide components provides designers and engineers with an in-stock source of wide-range, flexible waveguide solutions for their applications up to 50 GHz,” explains Steven Pong, RF Passive Components Product Manager at Pasternack. “Our rapidly expanding, ready-to-ship waveguide family is the largest in the industry and provides customers a comprehensive suite of waveguide solutions”
