The N-Type RF Surge Arrestor is engineered to safeguard high-frequency transmission systems from lightning strikes and electrical surges. Featuring precision N-type connectors, it provides excellent RF performance from DC to 18 GHz, supporting applications where stable connectivity and protection are essential.
The core protection element is a gas discharge tube (GDT) that instantly reacts to overvoltage events by conducting excess energy to ground, preventing equipment damage while maintaining signal integrity. Models with replaceable GDT cartridges enable quick and cost-effective maintenance.
Built with robust metal housing, including nickel-plated brass or stainless steel, the arrestor delivers superior mechanical strength, RF shielding, and corrosion resistance. Designed for 50-ohm systems, it ensures low insertion loss (<0.2 dB) and low VSWR (<1.2) across wide frequency bands.
Applications include base station antennas, RF distribution networks, and microwave radio systems, particularly in outdoor installations where weather resistance is critical. The N-type RF surge arrestor is a trusted solution for telecom, defense, and broadcast environments demanding reliable and consistent surge protection.

FAQ
Sample Delivery Time
Regular models require 15 days, while some complex connectors require 25 days.
Sample Fee
Most RF connectors are CNC-machined parts and do not require mold-making.
However, each part needs to be fine-tuned on the CNC machine. Typically, a single sample costs $200.
This fee will be refunded after a 5K bulk order.
Guarantee
Brass RF connectors come with a one-year warranty.
Stainless steel connectors come with a three-year warranty.
The lifespan also depends on the contact material beryllium contacts offer better durability.

What’s the lifespan of an RF connector?
Connector durability is rated in mating cycles: General-purpose connectors (BNC, SMA): 500 cycles. Precision connectors (2.92 mm, 2.4 mm): 500 cycles or less. Rugged telecom connectors (N, 7/16 DIN): 500 cycles.
Can RF connectors be reused?
Yes, but performance degrades with wear. Precision connectors (used in test equipment) should be handled carefully—damage to threads or pins increases VSWR and insertion loss.
What’s the difference between threaded, bayonet, and push-on RF connectors?
Threaded (SMA, N, TNC): Secure, vibration-resistant. Bayonet (BNC): Quick connect/disconnect. Push-on (MCX, SMP): Ultra-fast, compact, used in high-density modules.
Are RF connectors interchangeable between brands?
Yes, if they follow the same standard (e.g., SMA-to-SMA). However, tolerances, plating, and dielectric quality vary — mixing low-quality and precision connectors can damage equipment.
