Overview

CAES offers a full range of rectangular waveguide assemblies. Designed using decades of waveguide design expertise, we have a solution to meet all of your design needs.

CAES provides an extensive portfolio of rectangular waveguide assemblies.

Our rectangular waveguide assemblies include E-Bends, H-Bend, twists, straight and transition. In addition, we also offer custom waveguide assemblies as well as a range of cast bends in rectangular waveguide assemblies.

E-Bend

Rectangular E-Bend Waveguides

CAES offers a variety of formed E-bends with flanges covering waveguide sizes WR-22 through WR-430. VSWR is less than 1.10 maximum over the full waveguide bandwidth while insertion loss is equivalent to straight waveguide sections. Additional sizes, configurations and combinations are available on request.
