Type N
Type N Connectors
Description
Named after Paul Neill of Bell Labs after being developed in the 1940’s, the Type N
offered the first true microwave performance. The Type N connector was developed to
satisfy the need for a durable, weatherproof, medium-size RF connector with consistent
performance through 18 GHz.
There are two families of Type N connectors: Standard N (coaxial cable) and Corru-
gated N (helical and annular cable). Their primary applications are the termination of
medium to miniature size coaxial cable, including RG-8, RG-58, RG-141, and RG-225.
