Switching Unit


The switching unit is required for automatic redundancy switching of RF signals in the frequency range 5850 ... 6425 MHz.


The switching unit is housed in a 19" subrack with very good RF shielding and consists of the following sub-assemblies:

- coaxial relays DPDT
- coaxial amplifiers
- control logic with automatic switch over
- redundant power supply modules
- LAN interface
- mimic with manual control

All the necessary signal and power supply connections and mains switches are provided at the back.


The unit is controlled via LAN interface. The integrated webserver allows the unit configuration, shows status information and obtain trouble shooting information.

Special features

A status string can also be requested at any time via the control interface. The unit is constructed using a modular approach utilising plug-in sub-assemblies which enable ease of installation and maintenance.
