Below is a list of RF Connectors manufacturers from Lisle, Illinois. RF connectors, also known as radio frequency coaxial connectors, are a type of electronic connector that is specifically designed in order to work at radio frequencies within the multi-megahertz (Mhz) range. RF connectors are often described with the term “coaxial” in their name because they are commonly used in conjunction with coaxial cables and are specially designed in order to maintain the shielding required by the coaxial design. In addition, RF connectors typically have either a threaded or spring mechanism in their design.
