RF Railway components

EMP Protector

Track-side wireless applications require protection of RF and data cables to increase system availability and to lower the operational risk.

• High lightning current resistance
• Low residual energy
• Environmental protection IP68
• Frequency range 2-6 GHz
• Low Passive Intermodulation

DC-DC Blocks

Track-side and tunnel applications require DC-DC bocks to protect RF equipment from EM coupling, return currents and electro migration. Such effects are originating from transients in communication lines, non ideal ground potentials and DC traction power systems.

• DC disconnection of centre and outer conductor
• 4kV electric strength
• Covers both 2.4 and 5.6 GHz WiFi bands

High Voltage DC Block 9077.17.0035

Multiplexers

Within rolling-stock applications multiplexers are used to distribute and combine signals from different radio systems and roof-top antennas.

• Cellular, WiFi and WiMAX/LTE applications
• High channel isolation

Power Splitters

Symmetrical power splitters are often used in track-side and rolling-stock applications in order to use two antennas per access point.

• Frequency range 2-6 GHz
• Low loss and high power
• Easy to install
