n rf connector

n connector Type N is a kind of low to medium power connectors with screw coupling. Characteristic impedance has two types: 50ohm and 75 ohm. The characteristic of connector is high reliability , great vibration performance , excellent mechanical and electrical performance etc. they are used in connection with rf coaxial cable in radio instrument , communication equipment , microwave test and ground launch system at vibration and inclement weather circumstance. By using semi-rigid or semi-flex cable, this type will gain small VSWR, and the frequency can by up to 11GHz.
