Product Description

TYPE N is a kind of low to medium power connectors with screw coupling. Characteristic impedance has two types: 50ohm and 75ohm. 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 smaller VSWR, and the frequency can by up to 11GHZ.
