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.
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.

Dolph Microwave offers customized unit design based on customer requirement. All microwave waveguide components from us are produced with the highest quality and performance. ISO9001 Quality System is ensured. All Adapters are painted flat black with standard.
Waveguide to coax adapters, a type of mode transfer components between coaxial and waveguide, are composed of a waveguide component that fits the waveguide tubing and ends with a flange, and a coaxial probe assembly with a coaxial adapter and connection hardware. The standard waveguide to coax adapters are divided into right angle type and end launch type.
