The 7909D3 is a coaxial test port adapter with an NMD2.4mm female connector on one side and a Type N female connector on the other, designed for use with precision VNA test ports. It operates from DC to 18 GHz with a maximum VSWR of 1.08 below 4.0 GHz, 1.12 between 4.0 and 12.0 GHz, and 1.14 between 12.0 and 18.0 GHz. Its insertion length is 1.280 inches (3.25 cm). The adapter is ruggedized for repeated mating cycles and serves as a test port protector, preserving the VNA's original connector. It complies with IEEE 287 instrument grade connector standards for its interface types.
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 coaxial BNC, TNC, AFTNC, SMA, Type N, 7mm, 3.5mm, 2.92mm, 2.4mm and 1.85mm connectors up to 67 GHz, as well as with specialized NMD test port connectors and bulkhead connectors.
