Coaxial Connector Frequency Ranges

All RF coaxial connector types were designed with a specific purpose in mind. Certain applications require acceptable performance across a range of frequencies in conditions ranging from controlled laboratory settings (metrology, production test) to extremely harsh outdoor environments that need protection from wind, rain, ice, and extreme temperatures. In many instance, physical size is an issue both for space considerations and due to the diameter of the coaxial cables which must be accommodated.

Many time connectors are used quite successfully under conditions for which they were not designed for use. However, unless you have the luxury of being able to experiment or you have previous experience with the connector type, then it is best to stick with proven connectors for their designed-for uses. This chart will help you choose a coax connector based on frequency range.

See a discussion on transmission lines and coaxial connectors.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
