Type "N" Connectors The type N series coaxial connectors were originally designed as medium-size low voltage constant impedance 50 OHM connectors. Type N connectors found immediate popularity for microwave applications because of the 7 mm size air-filled mating interface. United Microwave Products has developed a complete line of precision type N series connectors. Constructed of stainless steel, Teflon dielectrics, and gold plated beryllium copper center contacts, these precision N connectors will mate nondestructively to the standard MIL-C-39012 interface. Additionally, United Microwave Products has extended the upper operating frequency to 18.0 GHz as compared to 11.0 GHz offered in MIL-C-39012. These precision type N connectors are offered for both semirigid and flexible cables, panel mount receptacles, inseries adapters, and strip-line transmission applications. Panel mount N connectors are available in both nickel plated brass & passivated stainless steel.
