Precision Coaxial Connectors (DC to 110 GHz)
|Publication Date:||22 March 2007|
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 test (DUT) independence. The standard presents updated test methods to utilize automatic vector network analyzers (VNAs) along with current state-of-the-art concepts in connector technology, and displays specification values from individual connector types in a connector summary table. A very important utility of this standard is that it serves as a user's guide. One unique feature of this standard is that it embodies the general requirements, definitions, measuring methods, and other pertinent 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 through Annex J, which are listed as follows
