Product Description: Calibration-grade metrology adapters have been designed as an integral part of Maury’s renowned vector network analyzer (VNA) calibration kits and are also available separately where calibration-grade precision is demanded. Calibration-grade metrology adapters offer the lowest VSWR reducing the mismatch between connected components and ensuring highest signal flow. Calibration-grade metrology adapters are available with waveguide-to-coaxial transitions with WR90, WR75, WR62, WR51, WR42, WR34, WR28 and WR22 flanges to 50 GHz in right-angle and end-launch configurations.
