RF connector

Male Type N RF connector.

A coaxial RF connector is an electrical connector designed to work at radio frequencies in the multi-megahertz range. RF connectors are typically used with coaxial cables and are designed to maintain the shielding that the coaxial design offers. Better models also minimize the change in transmission line impedance at the connection. Mechanically they provide a fastening mechanism (thread, bayonet, braces, push pull) and springs for a low ohmic electric contact while sparing the gold surface thus allowing above 1000 reconnects and reducing the insertion force. Research activity in the area of radio-frequency (RF) circuit design has surged in the last decade in direct response to the enormous market demand for inexpensive, high data rate wireless transceivers.^[1]

Standard types

• 7/16 DIN connector, a high power 50 Ω connector originally developed by Spinner^[2]
• BNC connector (Bayonet Neill-Concelman)
• C connector (Concelman)
• Dezifix connector, hermaphrodite connector used mainly by Rohde & Schwarz
• IEC 169-2 connector, also called Belling Lee connector or PAL, used throughout Europe and some other countries for domestic television installations and as FM connector for radio. It is standardised in EN 60169-2.
• F connector, used for domestic television installations and domestic satellite LNBs (75 Ω) world wide.
• GR connector (General Radio)
• HN connector, a high voltage version of the N connector
• MiniQuick
• Motorola connector, standard AM/FM antenna connector used for automotive radios
• Musa connector, a 50 Ω connector used in telecommunications and broadcast video
• N connector (Neill)
• NMO mount (new Motorola mount), for removable mobile antennas. Large threaded base for durability in wind.
• SC connector, screw version of C connector
• SMA connector, SubMiniature version A - also listed below in SubMiniature - Is a very popular lab equipment standard connector.
• TNC connector (threaded Neill-Concelman)
• Twin lead
• UHF connector (e.g., PL-259/SO-239). Also referred to as an M-type connector by Japanese manufacturers such as Kenwood

• Blind mate BMA, also known as OSP (Omni Spectrum Push-On) is used in a wide variety of RF and microwave interconnect applications to provide excellent electrical performance to 22GHz. The patented OSP interface has set the standard for blind mate RF/microwave connectors for over two decades.

• RCA connector (Radio Corporation of America) originally introduced for audio, but now widely used for video as well
• SCART
• List of coaxial connectors
• Concentric twinax connector
