Coaxial RF connectors are designed to operate at frequencies in the MHz or GHz range. They are used together with coaxial cable and are designed to maintain the best shielding with the cable. There are two main type of connections; threaded or bayonet-mounted. Different connectors are optimized for different frequency bands and power ratings.
Examples of contacts are F, BNC, TNC, 1.0 / 2.3, MCX, 7/16, SMA, N, 4.3-10, 3.5 mm, 2.92 mm and 2.4 mm.
Adapters make transitions between different types of contacts possible, or for adaptation between male and female contacts.
Coaxial cables are adapted for specific frequency bands, effects, signal losses and shielding. Some are very flexible while others are more rigid. Rigid cables are used in fixed designs where the cables do not need to be moved as often. The cable consists of an inner conductor surrounded by insulating layers and shielding. Cables can be optimized for different requirements such as low losses, phase matching, low intermodulation, impedance and reflection. Mechanical design is also important in applications where the cable is used more frequently and is subjected different types of stress.
