The following is a list of radio frequency connector types.

Standard types[edit]

Standard-sized[edit]

A double DIN 1.6/5.6 bulkhead jack connector, crimp type, for 75 Ω coaxial cable
A Type N connector (male), right-angled solder-type for semi-rigid coaxial cable with a diameter of 0.141 inch
  • 4.3-10 connector, a new proprietary connector not to be confused with DIN 4.3/10 one
  • Belling-Lee connector, also called IEC 169-2 connector, used throughout Europe and Australia for domestic television and FM radio antenna cabling
  • BNC connector (Baby Neill Constant)
  • C-type connector (Concelman)
  • Dezifix connector, hermaphrodite connector used mainly by Rohde & Schwarz
  • DIN 7/16 connector (DIN 47223), a high-power 50 Ω connector originally developed by Spinner[1]
  • F-type connector, used for domestic television installations and domestic satellite LNBs (75 Ω) worldwide with the exception of Europe and Australia
  • GR connector (officially the General Radio Type 874)
  • 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 connector (new Motorola mount), removable mobile antenna connector uses a 34 inch (19 mm) mounting hole and has a large base with a 1 1/8" - 18 tpi thread for attaching the antenna.
  • SC connector, screw version of C connector [not to be confused with the fiber optic connector of the same name]
  • SR connector (from Russian: Cоединитель Pадиочастотный) is a Russian RF connector, based on the BNC connector and which comes in a 50 Ω and 75 Ω versions
  • TNC connector (threaded Neill-Concelman)
  • Twin-BNC (Twinax) Twinax connectors are used with 78 Ω or 95 Ω conductor cables and operate from 0-200 MHz. Due to improved shielding characteristics, these connectors are used in balanced low level and high sensitivity circuits. They feature keyway polarization to ensure system integrity and prevent signals from being mixed, making them ideal for computer network applications. Other popular applications include broadband, military and instrumentation. The 2 stud bayonet clamp design allows quick and easy coupling without requiring special tools.
  • UHF connector (e.g., PL-259/SO-239). Also referred to as an M-type connector by Japanese manufacturers such as Kenwood

Miniature-sized[edit]

  • AFI connector
  • DIN 1.0/2.3 (DIN 47297), used for miniaturized 50 and 75 Ω coaxial modules in data- and telecommunications equipment which can have a threaded, or a push-pull lock coupling mechanism.
  • DIN 1.6/5.6 (DIN 47295), a 75 Ω connector, used for similar purposes as DIN 1.0/2.3
  • DIN 4.1/9.5
  • DIN 4.3/10
  • FME connector
  • G-type connector
  • HD-BNC connector
  • HSD connector, used in the automotive industry
  • LEMO 00 connector, a proprietary push-pull 50 Ω coaxial connector
  • MCX connector
  • Microdot S-50 series connector, a proprietary 50 Ω coaxial connector
  • Mini-BNC connector
  • Mini-UHF connector, a smaller and much newer design than the standard UHF
  • SMA connector A 50 ohm screwed connection. The 0.9mm centre pin is the same diameter as the centre of RG402 Coax so that connections to that cable can be made with no discontinuity, forming the pin from the coax itself. Good to 18GHz
    • RP-SMA connector, used in SOHO wireless networks and similar ISM band devices.
  • Air cored Microwave connectors The name of a connector (e.g. 1.85) is determined by the diameter in mm of the air dielectric around the centre pin
    • 3.5 and 2.92 mm (sometimes called K) connectors, which also have a 0.9mm centre pin and cross-mate with SMA and offer higher maximum frequency
    • 2.4, 1.85 (sometimes called V) externally similar to SMA but have metric threads and a smaller pin, and do not cross-mate with SMA. The 0.5mm centre pin is the same diameter as the centre of RG405 Coax so that connections can be made with no discontinuity, forming the pin from the coax itself.
    • 1.0 mm (sometimes called W) connectors, for applications to circa 110GHz
  • SMB connector
    • FAKRA connector is a modified SMB connector with plastic housing and latch, used in the automotive industry[2]
  • SMC connector
  • SSMA connector is a 50 Ohm nominal impedance RF connector which utilizes a 10-36 threaded coupling and is essentially a scaled down version of the SMA. They are characterized by compactness, high frequency bandwidth, and highly reliable mechanical performance. The male contact was designed to be the same size as the cable conductor so that it could be used as the mating pin for optimized VSWR. Common applications included Mil-Aero, telecommunications, RFID, antennas, test and measurement and radar systems.
  • SMZ connector - System 43 (BT43 and High Density HD43) for use in DDF. This is a 75 ohm impedance RF connector, and is ideal for instrumentation applications. Amphenol RF offers a large selection.

Micro-sized[edit]

  • AMC connector (Amphenol Micro Coaxial)
  • AMMC connector (Amphenol Micro-Miniature Coaxial)
  • HFM connector (High-Speed FAKRA-Mini), used in the automotive industry
  • Hirose U.FL connector
  • Hirose W.FL connector
  • IMP connector
  • Mini-SMB connector This is a 75 Ohm RF connector which provides broadband capability through 2 GHz. It's snap-on design offers a quick connect/disconnect. It features a reduced housing allowing circuit miniaturization and efficient space utilization. They are available for several cable types as well as for PCB through hole, surface mount and end launch applications from several manufacturers including Amphenol RF.
  • MMCX connector
  • MMS connector
  • MMT connector
  • PSMP connector
  • SSMB connector This is a 50 Ohm connector which is a small version of the standard SMB connector. They provide excellent electrical performance in a micro miniature footprint. The snap-on mating interface allows quick installation and dense packaging. Common applications include military, instrumentation, PC/LAN and wireless.
  • SSMC connector Are ideal for limited-space applications that require the security of a threaded coupling mechanism. They are best used with semi-rigid cables or miniature flexible cables in demanding applications up to 12.4 GHz
  • UMP connector

Precision types[edit]

Flanged types[edit]

  • EIA RF Connectors series of flanged connectors, normally used in high power broadcast transmission sites with rigid lines

Quick-lock types[edit]

A Mini Quick connector, a Quick-lock type connector for coaxial cable

High-voltage types[edit]

Blind-mate types[edit]

Key features of hermetic, push-on and blind-mate RF connectors are listed below:

RF Connector Name Compatibility Size Maximum Frequency Notes
Sub-Miniature Push-on (SMP) PO-compatible MIL-STD 348 compliant 26.5 GHz
Sub-Miniature Push-on Micro (SMPM) PPO-compatible MIL-STD 348 compliant 40 GHz
Sub-Miniature Push-on Sub-micro (SMPS) 3PO-compatible 65 GHz Small size makes SMPS the ideal choice for high density packaging and multiport applications
