I have a different SMA connector measurement question. Specifically for an SMA 905. I am having difficulty tracking down the standard that gives the ID specification for an SMA 905 connector. I have found IEC 61754-22 which replaced IEC 60874-2. Am I on the right track? These standards reference an F-SMA which I am not sure what the "F" stands for and I cannot be purchasing standards until I am fairly confident that I am on track. Any ideas will be appreciated? Thank you.
