Our Circular to Rectangular Transitions are precision electro-formed components which will enable you to connect standard rectangular waveguide to circular waveguide with a minimum of loss and reflections. Each transition contains a short section of standard rectangular waveguide which gradually transitions to a circular shape. Circular to Rectangular Transitions are available in sizes WR3 to WR42 with circular sizes ranging from 0.0455 inch to 0.4547 inch.

Ordering Example: CR28S-3150S is a circular to rectangular transition with WR-28 rectangular waveguide on one end, .3150" diameter circular waveguide on the other. Both ends would have square flanges.
