The N connector (in full, Type N connector) is a threaded RF connector used to join coaxial cables. It was one of the first connectors capable of carrying microwave-frequency signals, and was invented in the 1940s by Paul Neill of Bell Labs, for whom the connector is named.

Coaxial cable is an electrical cable consisting of a round, insulated conducting wire, surrounded by an insulating spacer, surrounded by a cylindrical conducting sheath, usually surrounded by a final insulating layer. ...

Originally, the connector was designed to carry signals of up to 1 GHz in military applications, but the common Type N today handles up to 11 GHz comfortably. More recent precision enhancements to the design by Julius Botka at Hewlett Packard have scaled this to 18 GHz. The male connector is hand-tightened and has an air gap between center and outer conductors. A gigahertz is a billion hertz or a thousand megahertz, a measure of frequency. ... HP redirects here. ... In electrical and mechanical trades and manufacturing, each of a pair of mating connectors or fasteners is conventionally assigned the designation male or female. ...


The N connector follows the MIL-C-39012 standard, defined by the US military, and comes in 50 and 75 ohm versions, the latter of which is used in the cable television industry. Connecting these two different types of connectors to each other can lead to damage.[citation needed] Unfortunately, many type N connectors are not labelled, and it can be difficult to prevent this situation in a mixed impedance environment. A United States Defense Standard, often called a military standard, MIL-STD, or MIL-SPEC, is used to help achieve standardization objectives by the U.S. Department of Defense. ... The ohm (symbol: Ω) is the SI unit of electric resistance. ... Coaxial cable is often used to transmit cable television into the house. ...

BNC connector - Wikipedia, the free encyclopedia (282 words)
The connector was named after its bayonet mount locking mechanism and its two inventors, Paul Neill of Bell Labs (inventor of the N connector) and Amphenol engineer Carl Concelman (inventor of the C connector).
The BNC connector is used for professional video connections, both for analog and Serial Digital Interface signals, amateur radio antenna connections, and on nearly every piece of electronic test equipment manufactured in the last 35 or so years.
BNC connectors were commonly used on 10base2 thin Ethernet networks, both on cable interconnections and network cards, though these have largely been replaced by newer Ethernet devices whose wiring does not use coaxial cable.
