Concept and Method of High Efficiency in a Precision Ka-band Subminiature Coaxial Connector

This article presents the design approach and test results of a Ka-band narrow flange receptacle (NFR), subminiature version A (SMA) connector based on transmission line theory, involving multi-step impedances and air-layer characteristics to increase ...
During the late 1950s and early 1960s, 7 mm coaxial transmission lines with standard SMA connectors were only used at frequencies between 10 and 12 GHz. In the mid-1960s, the US Department of Commerce established the Joint Industry Research Committee for the Standardization of Miniature Precision Coaxial Connectors (JIRF/SMPCC)....
