RF connector

From Wikipedia, the free encyclopedia

An 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.

[edit] Types

[edit] Standard types

• 7/16 DIN connector, a high power 50-ohm connector originally developed by Spinner^[1]
• BNC (Bayonet Neill-Concelman)
• C connector (Concelman)
• Dezifix connector, hermaphrodite connector used mainly by Rohde & Schwarz
• GR connector (General Radio)
• F connector, used for U.S. domestic television installations and domestic satellite LNBs (75 ohm)
• HN connector, a high voltage version of the N connector
• IEC 169-2 connector, also called Belling Lee connector used throughout Europe and some other countries for domestic television installations and as FM connector for radio. It is standardised in EN 60169-2.
• LC connector, type of large screw connector
• Motorola connector, standard AM-FM antenna connector used for automotive radios
• Musa connector, a 50-ohm connector used in telecommunications and broadcast video
• NMO mount (New Motorola MOunt), for removable mobile antennas. Large threaded base for durability in wind.
• N connector (Neill)
• SC connector, screw version of C connector
• TNC connector (Threaded Neill- Concelman)
• UHF connector (e.g. PL-259/SO-239) Also referred to as an "M-type" connector by Japanese manufacturers such as Kenwood

[edit] Miniature types

• Miniature BNC connectors
• Miniature UHF connectors
• DIN 47223 connectors
• U.FL connector
• SMZ - System 43 (BT43 and High Density HD43) for use in DDF

[edit] Sub-miniature types

• MMCX connector
• MCX connector
• FME connector
• SMA connector, including variants:
  • 3.5 and 2.92 mm connectors, which cross-mate with SMA, and
  • 2.4, 1.85 and 1.0 mm connectors, which do not cross-mate with SMA
• SMB connector
• SMC connector
• SMP connector

[edit] Precision types

• APC-7 connector

[edit] Flange connectors

• EIA RF Connectors series of RF flange connectors

[edit] Quick-lock connectors

• QMA and QN connector
• QLS connector
• SnapN connector
• CQMA, Mini-CQMA and CQN

• Antenna socket
• MHV connector, a coaxial connector designed for high voltages
• SHV connector, a safer coaxial connector designed for high voltages

The following audio and video connectors are sometimes used for RF, but are not generally considered to be RF connectors:

• DIN connector (not to be confused with the "7/16 DIN" connector)
• RCA connector (Radio Corporation of America) originally introduced for audio, but now widely used for video as well
• SCART
