Phoenix Transceiver System Surge Protection Lightning Arrester

Transceiver systems are highly vulnerable to surge damage. Antenna feeders spanning outside buildings are typically long, with cables and antennas directly exposed to the atmosphere.

Therefore, it is necessary to use coaxial-structured cables with characteristics compliant with EMC technology. However, this still cannot prevent the risk of coupled surges in antenna feeders and the formation of parasitic voltages at the highly sensitive interfaces of transceiver systems.

Nevertheless, surge protection can be employed to enhance the safety of directional wireless and mobile wireless systems. Local communication systems or video surveillance systems also require surge protection. For personal applications, special adapters are needed to provide surge protection for televisions and wireless devices.

Surge protection devices can significantly improve the safety of various transceivers. Utilizing these protective measures can greatly enhance the effectiveness and operational reliability of specialized equipment.

Coaxial Surge Protectors

Wireless transceiver systems are generally considered particularly sensitive to surge voltages. Antenna cables spanning buildings are often very long, and the antennas themselves are directly exposed to the atmosphere. Thus, it is essential to use coaxial-structured cables with characteristics compliant with EMC technology. Despite this, the risk of coupled surge voltages in antenna cables and the formation of parasitic voltages at sensitive interfaces of transceiver systems cannot be entirely eliminated. However, the use of surge voltage protection devices can enhance transceiver safety, making them almost immune to damage from transient surge voltages. The goal of these protective measures is to improve the availability and operability of specific devices.

Wireless Communication Systems and Mobile Phone Systems

Radio link systems can be used to bridge transmission paths where laying cables is difficult. This method enables communication for data processing equipment that is only used temporarily, for example. Coaxial antenna cables are connected to transmitters and receivers with BNC or N-type connectors. Protection devices with adapter structures can be easily inserted into the corresponding connectors. Since these devices operate at high transmission frequencies for antennas, gas discharge tubes are used as the coarse protection level.

Local Communication

Radio systems are used in all business sectors. Fire departments and emergency services utilize this wireless communication technology. Radio amateurs use many radio systems. Mechanical connections for antennas are typically made via UHF or N connectors. Suitable surge voltage protection devices feature such connection systems. Due to the high transmission frequencies, the protection circuit, composed of robust gas discharge tubes, is designed as a single stage.

Video Communication

In the field of building security, cameras are used for surveillance. Since equipment is often located in exposed positions, surge voltage protection devices are necessary to ensure camera availability. Coaxial surge voltage protection devices provide both coarse and fine protection.

Broadband Cables and Terrestrial Antennas

When lightning strikes near underground broadband cables or enters receiving antennas for televisions or radios, surge voltages can be coupled into antenna cables. In such cases, there is a risk of damaging broadband amplifiers, televisions, and radio antenna inputs. Surge voltage protection devices for these applications are designed as adapters with TV and radio connectors compliant with DIN 45 325 requirements.
