N Type RF Connectors

Please note that you only need to register as a member for the first time.

N (Type-Navy) type rf connectors have good frequency characteristics (DC to 12GHz) and are used in a wide range of radio communication equipment, mainly in the UHF band. The relatively large body with an impedance of 50Ω and threaded coupling method ensures reliable coupling. 75Ω N type rf connectors are also available, but they are in a different category and cannot be mated with the 50Ω N type rf connectors.

Some N type RF connectors are available for purchase from Digi-Key.

Trivia: The Origin of N

The connector is generally called Type-Navy, but it was invented in the 1940s by Paul Neal of Bell Laboratories in the US, and the name was taken from Neal's initials. It is sometimes called the Nancy connector to ensure the M connector is clear.

Trivia: UHF Band

UHF (Ultra High Frequency): Ultra High Frequency refers to radio waves between 300 MHz and 3 GHz. For example, the UHF band for television is 470–770 MHz, and the UHF band for RF-ID is 860–960 MHz. (Ministry of Internal Affairs and Communications)

Trivia: About Cables

JIS Standard
Japanese Industrial Standards (JIS) compliant cables. The higher the number of the part number, the thicker the cable. "D: 50Ω" and "C: 75Ω" represent the impedance.
MIL Standard
Compliant with US military standards for cables. Begins with the initials "RG" and is also called Mil-Spec.
Micro Coaxial Cables
Micro coaxial cables for attaching to miniature RF connectors such as U.FL.
Semi-flexible
Shape memory coaxial cables can be bent to a certain degree but have high shielding and low loss (attenuation).
Semi-rigid
A coaxial cable that uses a seamless metal tube to achieve higher shielding and less attenuation than semi-flexible cables.

Relatively large in size among coaxial connectors. The large connector size makes it possible to connect to thick coaxial cables. Because of their excellent weather resistance, they are often used outdoors at mobile base stations.

Trivia: Coaxial Cable Thickness

The thicker the coaxial cable, the less flexible it is, but the better the characteristics with less noise and loss. Usually, the longer the cable, the worse the characteristics, so the tendency is to select thicker cables.

We have a lineup of products that can be used in high-frequency bands from DC to 12 GHz.

N connectors are divided into 50Ω and 75Ω. Note that 50Ω and 75Ω type connectors cannot be combined.
