QCW Series Circular Waveguide Sections and Flanges

Characteristics

Available in Internal Diameter from 0.059-0.660 inch
Precise Dimensions

Product Description

QuinStar Technology offers circular waveguides (flanged and unflanged) for operation in the TE₁₁ mode for frequencies from 12 to 220 GHz in all standard and many custom internal diameters ranging from 0.059 to 0.660 inches. The bandwidth associated with these TE₁₁ mode circular waveguides is narrower than a typical rectangular waveguide in the same general frequency range. Since several internal circular waveguide diameters are applicable for a given frequency, please contact QuinStar with your specific requirement.

QuinStar also can supply circular-to-rectangular waveguide transitions (QWC series) for all applicable combinations of these circular and rectangular waveguides.
