Rectangular to Rectangular Transitions

Tapered Rectangular to Rectangular Transitions are used to transfer energy from one waveguide size to another with a minimum of reflections and loss. Our transitions are electro-formed on precision mandrels to obtain the best mode purity and minimize insertion loss. Rectangular to Rectangular Transitions are available in sizes WR3 to WR90. /p>

Ordering Example:

ET28S-8R is a transition from WR28 waveguide with a Square flange to WR8 waveguide with a Round flange. ET15R-5R is a transition from WR15 waveguide to WR5 waveguide with round flanges on both ends.
