N Connectors Introduction
N connector is a threaded RF connector and commonly is used to join with coaxial cable. N connector was invented in 1940’s and comes in 50 ohm and 75 ohm impedance.
The 50 ohm N connector is widely used in the infrastructure of wireless base station and cellular base station, and the working frequency normally is from hundred MHz to 5.8GHz. The 75 ohm N connector can work up to 1.5GHz, and is primarily used in the infrastructure of cable TV systems.
