QWP Series Waveguide Tapered Transitions

Characteristics

Low VSWR

Minimum Insertion Loss

Precise Construction

Product Description

QuinStar Technology's QWP series Waveguide Tapered Transitions are used to connect different rectangular waveguide sizes together with minimal loss of RF energy. These units feature strong, precise construction with low VSWR, and are offered in the frequency range of 18 to 220 GHz in ten waveguide bands, using standard flanges and waveguide sizes.

Additionally, for custom applications where nonstandard flanges and/or waveguide sizes are needed, in most cases these can be made available by special arrangement (please contact our Sales Department).
