Product Overview

N Series RF Connector

The N Series RF connector (Type N) by Aptiv Interconnect is a robust, medium-sized, threaded coaxial connector. Developed in the 1940s, it was among the first RF connectors to operate in the microwave frequency range (typically up to 11 GHz, with precision versions reaching 18 GHz). Its threaded coupling ensures a vibration-proof and weather-resistant connection, making it ideal for outdoor and demanding environments. The N Series is widely used in antennas, base stations, broadcast equipment, test & measurement instruments, radar, and wireless communications. Trust Aptiv Interconnect's N Series for critical RF connectivity.
