The 7809B4 is a precision coaxial adapter with an NMD1.85mm female connector on one end and a 3.5mm male connector on the other, designed for use with Keysight PNA series VNAs and similar test equipment. It operates from DC to 34.0 GHz with a maximum VSWR of 1.12 in the 20.0 to 34.0 GHz range. The adapter is 1.085 inches (2.76 cm) long, features ruggedized construction for long-term repeatability, and protects the VNA test port from wear. It complies with IEEE 287 standards for instrument-grade connectors.
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.
