Lightning Arrester DC-3000MHz N-M&N-F-Wall-through
Product Model: Arrester DC-3000MHz N-M&N-F
An RF lightning surge arrester is a critical passive protection device in RF communication systems. Its core function is to accurately discharge Instantaneous overcurrent such as lightning-induced overvoltage and power grid surges without affecting the transmission of normal RF signals. It protects expensive backend equipment including base station antennas, RF transceivers, and communication modules from damage caused by high-voltage impacts, while blocking the conduction of overvoltage along RF transmission links to ensure the stable and continuous operation of the entire communication system.

Product Description of RF lightning Surge Arrester
The RF lightning surge arrester is a critical passive protection device in RF communication systems. Its core function is to accurately discharge Instantaneous over current such as lightning-induced overvoltage and power grid surges without affecting the transmission of normal RF signals. It protects expensive backend equipment including base station antennas, RF transceivers, and communication modules from damage caused by high-voltage impacts, while blocking the conduction of overvoltage along RF transmission links to ensure the stable and continuous operation of the entire communication system.
This RF lightning Surge arrester features three core advantages:
1. Low Insertion Loss and High Voltage Standing Wave Ratio (VSWR)
Adopting a high-performance RF impedance matching design, it achieves an insertion loss ≤ 0.2 dB and a VSWR ≤ 1.2 within the operating frequency band. The attenuation effect on RF signals is negligible, fully meeting the signal transmission requirements of various communication systems.
2. Rapid Response and Precise Protection
Equipped with an integrated protection unit consisting of Metal Oxide Varistor (MOV) and Gas Discharge Tubes (GDTs), it boasts a response time of less than 1 ns. It can conduct and discharge current in an extremely short time upon the occurrence of transient overvoltage, and accurately distinguish between normal operating voltages and hazardous overvoltage to prevent signal interruption caused by false triggering.
3. High Reliability and Environmental Adaptability
The housing is made of high-strength metal material with an IP65 rating for dust and water resistance. It can operate stably in a wide temperature range from -40℃ to +85℃. With anti-salt spray and anti-corrosion treatment, it is suitable for long-term use in harsh environments such as coastal areas, deserts, and alpine regions, with a service life of over 10 years.
In addition, this arrester supports customization of various RF connectors including Type-N, SMA, and DIN. It features flexible installation, can be directly connected in series between RF feeder lines and equipment, and requires no additional debugging for convenient operation.
In terms of application scenarios, this RF lightning Surge arrester is widely compatible with various RF communication systems:
1. Mobile Communication Field
It can be deployed at the connection between antennas and feeder lines of 5G/4G base stations, as well as at the front end of RRU modules in distributed base stations. It resists lightning damage to base station equipment and reduces base station failure rates.
2. Radio and Television Field
It is applicable to the RF links of FM broadcast transmission towers and satellite ground receiving stations, protecting core equipment such as transmitters and receivers to ensure the continuity of signal transmission.
3. Radar and Navigation Field
It can be installed at the RF ports of radar antennas and navigation communication equipment to withstand surge impacts in complex outdoor electromagnetic environments, ensuring the detection accuracy of radar systems and the stability of navigation signals.
4. Internet of Things (IoT) and Private Network Communication Field
It is compatible with private network base stations in scenarios such as smart grids, rail transit, oilfields, and mines, providing reliable overvoltage protection for outdoor terminal equipment and facilitating the safe operation of industrial-grade communication systems.
With its high-performance and highly reliable protection advantages, this RF lightning Surge arrester serves as an indispensable safety barrier for RF communication systems, safeguarding the stable operation of communication equipment in various scenarios.
