N-Type RF Coaxial Connectors — High-Power Precision for Reliable RF Systems

The Backbone of RF Infrastructure

Every high-frequency network begins with a reliable connection. For decades, N-type RF coaxial connectors have served as the foundation for high-power communication systems, ensuring stable performance in even the most demanding environments.

Originally developed for military applications, the N connector quickly became the industry standard in base stations, radar arrays, and test instrumentation, thanks to its low loss, rugged design, and consistent 50 Ω impedance.

Today, as systems evolve from analog microwave to 5G and millimeter-wave networks, the N-type connector remains the trusted choice for engineers who value precision and endurance.

Designed for Strength, Built for Frequency

The N-type connector is not a compact connector — and that’s intentional. It’s engineered to handle high power levels with minimal signal loss. With frequency performance up to 18 GHz (and precision variants up to 26.5 GHz), this connector provides exceptional VSWR and return loss characteristics.

Its threaded coupling interface ensures mechanical stability, preventing signal disruption under vibration, wind, or thermal stress. This makes it indispensable in tower-mounted antenna systems, radar installations, and long-range microwave links, where maintenance and downtime are costly.

Built from brass, stainless steel, or nickel-plated materials, and featuring PTFE dielectric with gold-plated contacts, the N connector delivers both electrical precision and environmental resilience.

Power and Weather Resistance Combined

Outdoor RF systems face challenges that go beyond frequency performance — moisture, corrosion, and temperature fluctuations all threaten reliability. That’s why the N-type RF connector is built with gasket sealing, waterproof coupling, and robust plating to ensure IP67/IP68 protection.

In 5G antenna systems, satellite ground stations, and defense-grade radar networks, waterproof N connectors maintain consistent signal transmission under extreme conditions. They can endure years of exposure to rain, dust, and salt fog, without degradation in performance.

For system integrators, this means fewer maintenance cycles, longer operational uptime, and higher network availability.

Electrical and Mechanical Characteristics

These specifications make the N connector series one of the most durable and versatile in the RF coaxial connector family.

Real-World Applications

N-type RF connectors are deployed wherever power, precision, and protection are essential:

5G and LTE Infrastructure: High-power antenna-to-radio connections with low insertion loss

Radar & Defense Systems: Rugged connectors that perform under vibration and thermal cycling

Microwave Communication Networks: Reliable interconnects for long-distance signal paths

Aerospace & Ground Stations: High-frequency stability with waterproof sealing

Test and Measurement Equipment: Consistent calibration-grade performance

In each of these sectors, the N-type connector plays a quiet but crucial role — it’s the link that keeps complex systems communicating flawlessly.

Trusted Engineering for Decades

The N connector continues to earn its place in modern RF design not just because it’s strong, but because it’s predictable. Engineers know exactly how it will behave under stress, heat, and time. This predictability makes it ideal for both legacy microwave installations and next-generation communication networks.

Its compatibility with various RF cable types — from RG142 and LMR400 to semi-rigid coaxial cables — adds to its flexibility in field deployment and laboratory environments alike.

Customization, Supply, and Global Support

We offer a complete range of N-type RF coaxial connectors, including standard, reverse-polarity (RP-N), and waterproof IP-rated variants. Options include straight, right-angle, bulkhead, flange-mount, and cable-mount configurations.

Our connectors are fully RoHS and REACH compliant, manufactured under strict ISO quality systems. Each unit undergoes full VSWR and insertion loss testing, guaranteeing batch-to-batch consistency.

We also provide BOM kitting, stock sourcing, low MOQ, and short lead times to support global OEM/ODM customers. Our engineers work closely with clients to ensure every connector fits seamlessly into the final design — from the lab bench to the field.

The Future of High-Power RF Connectivity

As RF systems move into higher power densities and 5G backhaul frequencies, the N-type connector remains a cornerstone of robust interconnect design. Its combination of mechanical strength, RF precision, and environmental sealing makes it a long-term solution for both current and future communication infrastructure.

In a world of rapid innovation, the N connector series stands for something timeless — reliability you can measure, and performance you can trust.
