    en.wikipedia.org/wiki/List_of_RF_connector_types

    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 ...

  3. Test probe - Wikipedia

    en.wikipedia.org/wiki/Test_probe

    Active scope probes use a high-impedance high-frequency amplifier mounted in the probe head, and a screened lead. The purpose of the amplifier is not gain, but isolation (buffering) between the circuit under test and the oscilloscope and cable, loading the circuit with only a low capacitance and high DC resistance, and matching the oscilloscope ...

    They are commonly referred to by the inner diameter of the outer conductor in fractional inches. Sizes covered under these two standards range from 3/8 to 6 1/8 inch outside diameter (OD) for 50 Ω and 3/8 to 3 1/8 inch OD for 75 Ω.

  5. RG-58 - Wikipedia

    en.wikipedia.org/wiki/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 material ...

  6. High frequency - Wikipedia

    en.wikipedia.org/wiki/High_frequency

    High frequency (HF) is the ITU designation [1] for the band of radio waves with frequency between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters).

  7. BNC connector - Wikipedia

    en.wikipedia.org/wiki/BNC_connector

    The BNC connector 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 and radio frequency connections up to about 2 GHz and up to 500 volts.

  8. VLF cable testing - Wikipedia

    en.wikipedia.org/wiki/VLF_cable_testing

    Frequency ranges used are within the range of 0.01 Hz to 0.1 Hz, where frequency selection depends on the load presented by the cable. Test voltage levels are either calculated using a multiple of the cable's nominal phase-phase voltage or via tables in IEEE 400.2; typically they are in the range of 1.5 U0 to 3 U0.

  9. Coaxial cable - Wikipedia

    en.wikipedia.org/wiki/Coaxial_cable

    Coaxial cable is a type of transmission line, used to carry high-frequency electrical signals with low losses. It is used in such applications as telephone trunk lines , broadband internet networking cables, high-speed computer data busses , cable television signals, and connecting radio transmitters and receivers to their antennas .
