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]], after whom the connector is named.

==Design==
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 [[gender of connectors and fasteners|male]] connector is hand-tightened and has an air gap between center and outer conductors. The coupling has a 5/8-24 [[Unified Thread Standard|thread]].

==Usage==
The N connector follows the MIL-C-39012 standard, [[Defense Standard|defined by the US military]], and comes in 50 and 75 [[Ohm (unit)|ohm]] versions. The 50 [[Ohm (unit)|ohm]] version is widely used in the infrastructure of land mobile, wireless data, paging and cellular systems. The 75 [[Ohm (unit)|ohm]] version is primarily used in the infrastructure of [[cable television]] systems. Connecting these two different types of connectors to each other can lead to damage due to the difference in diameter of the center pin. Unfortunately, many type N connectors are not labeled, and it can be difficult to prevent this situation in a mixed impedance environment.

The 50 [[Ohm (unit)|ohm]] type N connector is favored by enthusiasts who create their own [[Wireless LAN]] antenna systems, which run at 2.4 GHz or 5 GHz. The [[Cantenna]] is one such design. The enthusiasts have settled on using the N connector as a standard connection for homebrew antennas. By using a cable with an N connector one can easily interchange homebrew antennas. 50Ω N connectors are also commonly used on [[amateur radio]] devices (e.g., [[transceiver]]s) operating in [[UHF]] bands.

==Variations==
'''SnapN''' was originally designed by Rosenberger Hochfrequenztechnik in 2006 and is a quick locking replacement for the threaded interface of the widely applied Type N connector. Though part of the Quick Lock Formula Alliance (QLF), engineers at Rosenberger independently designed the SnapN in order to correct the performance issues of QLF’s version of the quick lock N connector, QN. This design achieves better electronic performance because, unlike the QN, this new version maintains the basic structural parameters of the original Type N in which the inner dimensions of the outer conductor are 7.00 mm, and the inner conductor’s outer dimensions are 3.04 mm.
