Editing BNC connector (section)

==Description ==

The BNC connector features two bayonet lugs on the female connector; mating is fully achieved with a quarter turn of the coupling nut. It uses an outer conductor with slots and some plastic dielectric on each gender connector. This dielectric causes increasing losses at higher frequencies. Above 4&nbsp;GHz, the slots may radiate signals, so the connector is usable, but not necessarily stable, up to about 11&nbsp;GHz. BNC connectors are made to match the [[characteristic impedance]] of cable at either 50 ohms or 75 ohms (with other impedances such as 93 ohms for [[ARCNET]] available though less common). They are usually applied for frequencies below 4&nbsp;GHz<ref name=Lee04/> and voltages below 500 volts.<ref name="amphenol">[http://www.amphenolrf.com/connectors/bnc.html BNC Connector specifications], Amphenol Connex</ref> The interface specifications for the BNC and many other connectors are referenced in MIL-STD-348.<ref name="MIL-STD-348">{{cite book |title=RADIO FREQUENCY CONNECTOR INTERFACES FOR MIL-DTL-3643, MIL-DTL-3650, MIL-DTL-3655, MIL-DTL-25516, MIL-PRF-31031, MIL-PRF-39012, MIL-PRF-49142, MIL-PRF-55339, MIL-DTL-83517 |date=2017-01-22 |publisher=US DOD |edition=B with change 3 |url=http://quicksearch.dla.mil/qsDocDetails.aspx?ident_number=35726}}</ref>
