Seamless Semi-Rigid Flange to Flange Adapter

A low loss, hand formable waveguide section suitable for millimeter wave applications.

At millimeter wave frequencies flexible waveguides are often not available or the performance and reliability are considered unsatisfactory. For most applications a low loss flexible section that could be bent or formed a few times might be all that is required.

To meet the needs of this type of application Flann have introduced the Series 562 range of Seamless Semi-Rigid Waveguides which provide a low loss formable section encased in a ruggedised jacket with an insertion loss comparable to that of drawn copper waveguide.
