Waveguide Adapters

Dolph Microwave manufactures a wide range of waveguide to coax adapters covering all waveguide bands from WR2300 to WR10, which is available for most standard waveguide to coax adapters.

Additionally Dolph Microwave still offers precision type with almost perfect VSWR and Low insertion loss with both groove, flat, chock and customized flange as option.

Ordering Guide of Waveguide Adapters

Flange type: Multiple types available - see Technical Reference page

Finish: Corrosion protection plus black/grey top coat

Standard unit provided not sealed pressure tight unless otherwise specified

Note: All Dolph Microwave waveguide adapters include an anti-corrosion protection treatment, painted flat black. For other flange finishes, material or paint color requirements please specify or check our custom microwave components page. Precision type with perfect VSWR and IL are still available as option.
