RF coaxial connectors

RF coaxial connectors provide vital RF links in communications, broadcast, EMC testing, commercial and military, as well as test and measurement fields. While there is a vast array of RF connectors available, they are all characterized by just a few key parameters. The most obvious characteristic of a connector is its physical size. Other considerations include power handling and frequency range capabilities. To insure maximum power transfer, the characteristic impedance of the connector should match the source and load. All of these characteristics along with connector durability and cost must be considered in light of the specific application. This application note provides guidance and insight in choosing connectors best suited to accommodate your specific application.

Let’s begin by reviewing the most commonly found connector types in RF applications. These ubiquitous “traditional” connectors are available in both male and female configurations, standard and precision grades, high frequency and in some cases high power versions.
