Phoenix Contact RF Surge Protectors

Transceiver systems in remote locations are particularly susceptible to surge voltages resulting from lightning strikes or nearby strikes. Antenna cables which extend beyond the building and are very long, as well as the antenna themselves, are directly exposed to lightning strikes. For this reason, cables with a coaxial structure are used. The shield of the antenna cable can either be grounded or floating, however, the risk of surge voltage coupling in the antenna cables is not completely eliminated. Surge voltages can reach the sensitive interfaces of transceiver systems through the cable path.

Phoenix Contact RF surge protectors are equipped with powerful gas-filled surge protective devices or with the Lambda/4 technology. The Lambda/4 technology uses a short circuit between the inner conductor and the shield. The length of the cable between the short circuit and the inner conductor matches the frequency that is allowed to pass through without attenuation. Lambda/4 protective devices can transmit relatively wide bandwidth signals, from 0.8 - 2.25 GHZ, while achieving a very good (low) voltage protection level.

Phoenix Contact RF surge protection devices for radio and television receivers are mounted between the antenna wall connection and the outgoing antenna cable. For satellite receivers, there are multi-channel protective devices for wall mounting. Satellite receivers are connected using F connectors and broadband cable and antenna connections are generally TV and RF connectors. As a general rule, coaxial attachment plugs that are used with protection devices have BNC or TNC connectors. N, SMA or 7/16 DIN connectors are used with protective devices for various radio link technology.
