This standard concerns pin and socket r.f. coaxial connectors, with screw coupling mechanism, for low to medium power applications. The connector is commonly known as the "Type N". Three versions of the 50 Ω characteristics impedance Type N connector are included, each version being mateable with each of the others. The general purpose connector (Grade 2) derived from the United States of America specifications MIL-C-71B and MIL-C-39012 may preferably be used with r.f. cable 96 IEC 50-7 up to about 12 GHz maximum frequency. The high performance connector (Grade 1) is particularly suitable for microwave applications when lower reflection factors than are offered by the General purpose connector are required. The connector may also be suitable for microwave components. The tolerances of the interface dimensions lie between those for Grade 0 and Grade 2, and are chosen to give the performance required. Some Grade 1 connectors conforming to this standard may be used up to 18 GHz maximum frequency. The standard test connector (Grade 0) has a closely controlled interface to provide a reference for the measurement of connectors, cable assemblies, components and equipment with the above two interfaces. It may also be used as a microwave connector in situations when the most precise interface for use up to 18 GHz maximum frequency is required. A 75 Ω characteristic impedance connector is given in Appendix A even though the use of 75 Ω Type N connectors is strongly deprecated.
