The Type N connector was developed to satisfy the needs for a durable, weatherproof, medium-size RF connector with consistent performance through 11 GHz. The N connector is the most practical and popular coaxial cable connector for 7mm *inner diameter of outer conductor) of 50W group. The coaxial connector can be supplied with characteristic impedances 50 ohm and 75 ohm. The thread coupling incurs low noise and withstands shock and vibration. Applications include power transmitters, communication base station, antennas, cable-based LAN systems, and test and measurement equipment.
