A coaxial RF connector (radio frequency 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, blind mate) and springs for a low ohmic electric contact while sparing the gold surface, thus allowing very high mating cycles and reducing the insertion force. Research activity in the area of radio-frequency (RF) circuit design has surged in the 2000s in direct response to the enormous market demand for inexpensive, high-data-rate wireless transceivers.[1]

Miniature types[edit]

Sub-miniature types[edit]

  • 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
    • FAKRA - Modified SMB connector with plastic housing and latch used in the automotive industry.[3]
  • SMC connector
