The scope of this standard is to specify coaxial connectors for precision electrical measurements to110 GHz. The frequency range of the standard is increased from 65 GHz to 110 GHz since in the marketexists a 1 mm connector with a rated upper minimum operating frequency of 110 GHz. The members of thesubcommittee felt, in view of this, the scope of the project should be changed to incorporate this advantage.
Purpose
The purpose of this standard is to present minimum performance requirements for those precisionconnectors whose upper frequency limits range from 18 GHz to 110 GHz for five line sizes of the pin andsocket type, which include 3.5 mm, 2.92 mm, 2.4 mm, 1.85 mm, and 1.0 mm connectors. It also incorporatesrelevant information on the 14 mm and 7 mm connector types, includes the Type N (7 mm) connector, andintroduces the performance requirements needed to standardize pin and socket type connectors. A novelfeature in this standard is the use of slotless socket contacts for some pin and socket type connectors tomaintain the concept of test port/device under test (DUT) independence. The standard presents updated testmethods to utilize automatic vector network analyzers (VNAs) along with current state-of-the-art conceptsin connector technology, and displays specification values from individual connector types in a connectorsummary table. A very important utility of this standard is that it serves as a user s guide. One unique featureof this standard is that it embodies the general requirements, definitions, measuring methods, and otherpertinent information into one document for all eight standard connector types while making use of the detail specifications information from each connector type for standardization into Annex C throughAnnex J, which are listed as follows:Annex C Detail specifications for precision coaxial 14 mm connectors (DC to 8.5 GHz)Annex D Detail specifications for precision coaxial 7 mm connectors (DC to 18 GHz)Annex E Detail specifications for precision coaxial Type N connectors (DC to 18 GHz)Annex F Detail specifications for precision coaxial 3.5 mm connectors (DC to 33 GHz)Annex G Detail specifications for precision coaxial 2.92 mm connectors (DC to 40 GHz)Annex H Detail specifications for precision coaxial 2.4 mm connectors (DC to 50 GHz)Annex I Detail specifications for precision coaxial 1.85 mm connectors (DC to 65 GHz)Annex J Detail specifications for precision coaxial 1 mm connectors (DC to 110
