What is an N Connector?

The Type "N" connector, commonly known as the N connector, is used to join coaxial cables using a threaded RF connector. It was one of the first connectors to be capable of carrying microwave-frequency signals. Invented by Paul Neill of Bell Labs in the 1940s, the connector is named after him.

Design Details

These connectors were devised to carry signals that could reach 1 GHz in certain military applications. The Type N connector that is commonly used today can easily handle up to 11 GHz. However, that was just the beginning. Precision enhancements made to the design by Julius Botka from Hewlett Packard extended the range to a massive 18 GHz. The male connector is generally hand-tightened, leaving an air gap between outer conductors and the center.

The N connector follows the MIL-C-39012 standard (defined by the military) and comes in 50 and 75 ohm versions. The cable television industry is largely dependent on the latter 75-ohm versions. Note that connecting the two connectors to each other may cause some damage. The problem is that many N connectors available for use are not labeled, so preventing their use in a mixed-impedance environment can be difficult.

The N connector is commonly used by those who prefer to create their own Wireless LAN antenna systems, which run at both 2.4 GHz or 5 GHz. These Wireless LAN manufacturers have opted to use the N connector as their standard connection. Using an N connector with a cable makes interchanging antennas really easy and comfortable.

Features and Benefits

N connectors allow room for an extensive range of medium-to-miniature RG coaxial cables in the form of a rugged medium-sized pattern.
A broad range of military, industrial, and commercial grade products are available for consumers, allowing them to compare quality and pricing before buying.
Different plug styles, such as right angle, jack-styled or straight, are available to meet the demands of the customers. Receptacle and bulkhead mounts are two of the popular kinds that are available in the panel mount.

Owing to the popularity of the N connector, it has diversified into a number of types for use in specific environments. You can browse the Internet for a list of specifications and product details.
