  2. RG-58 - Wikipedia

    en.wikipedia.org/wiki/RG-58

    RG-58. RG-58/U is a type of coaxial cable often used for low-power signal and RF connections. The cable has a characteristic impedance of either 50 or 52 Ω. "RG" was originally a unit indicator for bulk RF cable in the U.S. military's Joint Electronics Type Designation System. There are several versions covering the differences in core ...

  3. RF connector - Wikipedia

    en.wikipedia.org/wiki/RF_connector

    RF connector. Time-domain reflectometry shows reflections due to impedance variations in mated RF connectors. An 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 ...

  4. SMA connector - Wikipedia

    en.wikipedia.org/wiki/SMA_connector

    SMA ( SubMiniature version A) connectors are semi-precision coaxial RF connectors developed in the 1960s as a minimal connector interface for coaxial cable with a screw-type coupling mechanism. The connector has a 50 Ω impedance. [ 1] SMA was originally designed for use from DC (0 Hz) to 12 GHz, however this has been extended over time and ...

  5. 10BASE2 - Wikipedia

    en.wikipedia.org/wiki/10BASE2

    10BASE2 cable end terminator. 10BASE2 (also known as cheapernet, [ 1] thin Ethernet, thinnet, and thinwire) is a variant of Ethernet that uses thin coaxial cable terminated with BNC connectors to build a local area network. During the mid to late 1980s, this was the dominant 10 Mbit/s Ethernet standard. The use of twisted pair networks competed ...

  6. BNC connector - Wikipedia

    en.wikipedia.org/wiki/BNC_connector

    Cable. Coaxial. Passband. Typically 0–4 GHz. The BNC connector (initialism of "Bayonet Neill–Concelman") is a miniature quick connect/disconnect radio frequency connector used for coaxial cable. It is designed to maintain the same characteristic impedance of the cable, with 50 ohm and 75 ohm types being made. It is usually applied for video ...

  7. Standing wave ratio - Wikipedia

    en.wikipedia.org/wiki/Standing_wave_ratio

    Voltage standing wave ratio (VSWR) (pronounced "vizwar" [ 1][ 2]) is the ratio of maximum to minimum voltage on a transmission line . For example, a VSWR of 1.2 means a peak voltage 1.2 times the minimum voltage along that line, if the line is at least one half wavelength long. A SWR can be also defined as the ratio of the maximum amplitude to ...

  8. List of RF connector types - Wikipedia

    en.wikipedia.org/wiki/List_of_RF_connector_types

    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 18 GHz

  9. Characteristic impedance - Wikipedia

    en.wikipedia.org/wiki/Characteristic_impedance

    The characteristic impedance of an infinite transmission line at a given angular frequency is the ratio of the voltage and current of a pure sinusoidal wave of the same frequency travelling along the line. This relation is also the case for finite transmission lines until the wave reaches the end of the line. Generally, a wave is reflected back ...
