The Maury MPC14 connector is a precision 14 mm connector that is essentially equivalent to, and mating compatible with, GR900 type connectors. It incorporates an improved Hex/Knurl Coupling Nut and an improved center conductor inner contact (Model 2481A). the coupling nut has a 1.00-inch hex portion for accurate tightening with a torque wrench and a knurled portion, which provides a positive grip for finger tightening. By torquing the coupled junction, measurement repeatability and accuracy are enhanced. Frequency range is DC to 8.5 GHz. All adapters feature low VSWR and insertion loss.
