Waveguide to Coax Adapters
Microtech's Waveguide to Coax Adapters are engineered, designed, and manufactured "in house".
Microtech, Inc. Waveguide to Coax Adapters are made from a precision extruded tubing with the end caps silver or dip brazed to give you a precise and durable unit for both lab and systems use over the full specified operating band, with a minimum VSWR and Insertion Loss. These units can be built to be pressure tight on request.
