RF and Microwave Connectors

Radio frequency (RF) and microwave connectors are used to connect the ends of cables in systems that operate in the radio frequency or microwave spectrum. Microwave refers to electromagnetic energy with a frequency higher than 1 gigahertz and a wavelength shorter than 30 centimeters. Radio frequency refers to alternating current which generates an electromagnetic field suitable for wireless broadcasting and/or communications if the current is input to an antenna. An RF connector can be found in transmission systems and allows for the coupling or uncoupling of system components. A mated pair consists of a plug and a jack.

Connector Classifications

There are three basic ways to categorize RF connectors:

• Cable connectors include plugs and jacks which terminate cables.
• Receptacles include plugs and jacks which terminate to printed circuit boards.
• Equipment chassis and adapters are used to join multiple incompatible units in, or between, series.
