An RF connector, also known as an RF connector, is generally considered to be an element attached to a cable or mounted on an instrument as an electrical connection or separate component of the transmission line. The RF connector is a mechatronic product that serves primarily as a bridge. The following is a description of the RF connector code .

    N connectors: Threaded RF coaxial connector with an outer conductor of 7 mm (0.276 in.) and a characteristic impedance of 50 Ω (75 Ω). (IEC169-16).

    BNC connectors: bayonet-locked RF coaxial connector with an outer conductor of 6.5 mm (0.256 in.) and a characteristic impedance of 50 Ω. (IEC169-8).

    TNC connectors: Threaded RF coaxial connector with an outer conductor inner diameter of 6.5 mm (0.256 inch) and a characteristic impedance of 50 Ω. (IEC169-17).

    SMA connectors: Threaded RF coaxial connector with outer conductor inner diameter of 4.13mm (0.163 inch) and characteristic impedance of 50Ω. (IEC169-15).

    SMB connectors: push-in locking RF coaxial connector with outer conductor inner diameter of 3mm (0.12 inch) and characteristic impedance of 50Ω. (IEC169-10).

    SMC connectors: Threaded RF coaxial connector with outer conductor inner diameter of 3mm (0.12 inch) and characteristic impedance of 50Ω. (IEC169-9).
