Popular science N-type connector concept

Author: Date:11/28/2019 2:05:46 AM
    What is the N-type RF coacial connector? What is your knowledge of the N-series RF coaxial connector? The N-type RF coaxial connector is one of the RF coaxial connectors.        The following day will explain to you. I hope to help you with the knowledge of N series RF coaxial connectors.

    According to the definition of Baidu Encyclopedia, N series RF coaxial connectors are small and medium power RF coaxial connectors with screw connection mechanism developed according to MIL-C-39012 standard. The characteristic impedance is 50Ω and 75Ω, and the frequency range is 0~11GHz. It has strong anti-vibration, high reliability and superior mechanical and electrical performance. It is widely used in wireless equipment such as radar, broadcasting and communication.

    Introduction to N Series RF Coaxial Connectors

    N Series RF Coaxial Connectors SERIES RF COAXIAL CONNECTORS

    The N series is a threaded medium power connector with high reliability, strong vibration resistance, excellent mechanical and electrical performance, and is widely used in radio equipment and instruments and ground launches under harsh vibration and environmental conditions. The system is connected to an RF coaxial cable.
