N-Type coax connector: engineering & RF performance
RF N-Type connectors are constructed with brass bodies available in gold or nickel plating. By utilizing PTFE or styrene insulators, this configuration ensures stable electrical performance across various environments.
The 5/8-24 threaded coupling mechanism prevents mechanical disconnects under high vibration, withstanding a minimum retention force of 100 lbs. For reliable and secure installation, the recommended mating torque is 8 to 12 in-lbs.
Coax N connector standard configurations operate from DC to 11 GHz, while extended-range designs maintain signal integrity up to 18 GHz. They support high-power requirements with a 300 W capacity at 10 GHz and a low PIM of -166 dBc. Additionally, these connectors seamlessly accommodate industry-standard coaxial cables including RG-213, LMR-400, RG-55, and RG-174.
