Dolph Microwave offers a standard product line of waveguide short plates which provide high reflection short circuits for terminating all standard waveguides. It offers a cover, all-clear configuration as a standard product. Alternate materials and configurations are available upon request. Waveguide offset and sliding short are also available.
Flange type: Multiple types available - see Dolph Microwave Flanges page.
Finish: Corrosion protection plus black/grey top coat.

Waveguide offset short can be chosen with standard 1/8, 1/4, and 3/8 shorting distance, designed close to the center frequency of each waveguide size, which is to allow the units to have extraordinary electrical performance across each of the different waveguide frequency bands. It is mainly for VNA calibration kit applications.
