Standardization of precision coaxial connectors

Previous work in precision coaxial connectors for air lines and improvement of coaxial cable connectors is reviewed. The current philosophies and resulting Standards of the United States of America Standards Institute's Subcommittee C83.2 and the Institute of Electrical and Electronics Engineers' Subcommittee on Precision Coaxial Connectors are discussed. Techniques for improved VSWR measurements needed in the development of precision coaxial connectors are described. Applications, development plans, and unresolved problems are mentioned.
