High-Performance N Type Connector Female for 7/8″ Flexible RF Cable
Product Introduction:
Equip your telecom infrastructure with uncompromising signal clarity using the NF-7/8″L N Straight Female Connector. Engineered precisely for 7/8″ flexible RF cables, this rugged, low-PIM (≤-155dBc) component delivers true IP68-rated weatherproofing and seamless frequency performance from DC to 11GHz. As a reliable solution for minimizing signal loss, it is ideal for modern Distributed Antenna Systems (DAS), In-Building Antenna Systems (IBS), and mission-critical public safety networks.
Engineered for Global Telecom Excellence
When showcasing our latest RF passive components to global telecom leaders at major industry events like MWC Barcelona, the demand for reliable, low-interference connections is always a focal point. At Hefei BRI Electronic & Technology Co., Ltd., we design every female n connector to meet these exacting global standards.
Designed for seamless integration with 7/8″ flexible RF cables, this n type connector female guarantees exceptional electrical performance and mechanical durability in both indoor and harsh outdoor environments.
Superior Low-PIM Performance: Rated at PIM3 (2*43dBm) ≤-155dBc, it drastically cuts down passive intermodulation for cleaner, uninterrupted signal transmission.
Military-Grade Durability: Tested to MIL-STD-202 standards for mechanical shock and vibration, ensuring it stands up to extreme physical demands.
Heavy-Duty Construction: Features a brass body with trimetal plating and inner contacts with silver plating for optimal conductivity and corrosion resistance.
Complete Weather Protection: An IP68 sealing class (24hr, 1m, 20°C) ensures complete defense against dust and water immersion.
