This standard presents the combined efforts of IEEE Subcommittee P287 that reflect the knowledge and experience of leading specialists in the development and measurement of precision coaxial connectors from dc to 110 GHz. It presents minimum performance requirements to standardize both hermaphroditic and pin- and socket-type connectors. It provides recommended electrical and mechanical test procedures for general and laboratory precision connectors. A bibliography provides a list of pertinent references for measurement techniques used in determining electrical, mechanical, and dimensional parameters for coaxial connectors.

The scope of this standard is to specify coaxial connectors for precision electrical measurements to 110 GHz. The frequency range of the standard is increased from 65 GHz to 110 GHz since in the market exists a 1 mm connector with a rated upper minimum operating frequency of 110 GHz. The members of the subcommittee felt, in view of this, the scope of the project should be changed to incorporate this advantage.

The purpose of this standard is to present minimum performance requirements for those precision connectors whose upper frequency limits range from 18 GHz to 110 GHz for five line sizes of the pin and socket type, which include 3.5 mm, 2.92 mm, 2.4 mm, 1.85 mm, and 1.0 mm connectors. It also incorporates relevant information on the 14 mm and 7 mm connector types, includes the Type N (7 mm) connector, and introduces the performance requirements needed to standardize pin and socket type connectors. A novel feature in this standard is the use of slotless socket contacts for some pin and socket type connectors to maintain the concept of test port/device under tes...
