Waveguide Bends & Twists


Made to order, these bends and twists feature precision machining from solid copper alloy, a gold plated finish and a choice of flanges compatible with the latest standards. They are primarily aimed at frequencies beyond 100 GHz where precision and high quality are mandatory for optimum performance. Bends and twists manufactured from drawn waveguide with fitted flanges are also available, and are generally suited to requirements below 100 GHz, or where long runs of waveguide are needed.

General Features

  • High precision
  • Custom lengths
  • Low loss
  • Up to 750 GHz
  • Physically robust

1. New definitions for use above 110 GHz have been proposed by IEEE in order to accomodate standards up to 1.1 THz.
2. There are variations in industry 'standard' flanges.When ordering waveguides > 100 GHz advise required flange PIN and hole dimensions.
3. Waveguide WR 03 historically covers 220-325 GHz however the new standard WM-864 extends coverage to 220-330 GHz.
4. How to Order : specify Model number with required length eg. VTWGE-1.5-50 is an E plane bend in WR1.5 with a length of 50 mm.
