Radio Frequency Connectors are interconnecting devices often used in systems that operate in the radio frequency and microwave. Rf Connectors are used to interconnect RF equipment and components. Some RF connectors are used in high-speed digital communication systems. OSM connectors most commonly used RF connectors and intended for use in semi-rigid cables. Precision SMA Connectors belong to "primary interconnects" and "precision measurement" categories for they are meant to bridge the gap between the two uses. Some RF connectors are used for satellite applications and are used in lower earth orbits. SSM or Sub, sub miniature connectors are very small in size. These connectors are offered in both male and female configurations. The male RF connector is mounted on a circuit board. The BNC connector is designed for military use and has widely accepted in video and RF applications. The BNC uses a slotted outer conductor and some plastic dielectric on each gender connector. These connectors are available in different frequency ranges.
