L-Band Dual Redundancy RF Switching System

RFS8 is a 19” Rack EXTENDED L-BAND LINE AMPLIFIER & REDUNDANCY RF SWITCHING SYSTEM.

The RFS8 Rack interfaces up to 8 MAIN and 8 BACKUP L-BAND signals with monitoring capabilities to
switch to a backup signal with a programmable RF power threshold.

This system has a Split architecture to reduce assembly and maintenance costs. Built with N.4 HOTSWAP
modules on the rear side of the chassis (DRA4), having n. 4 L-Band Amplifiers each and with
N.4 HOT-SWAP modules on the front side of the chassis (DRS2), having n.2 switches to automatically
provide the proper RF output for each couple of L-Band input signals.

The double redundant PSU intelligent technology allows an immediate switch on the secondary
power source.

This technology ensures continuous quality of service and the hot swap Modules can be easily
replaced by the local personal.

An advanced monitoring system provides all measurements and alarms locally or remotely via WEB
or SNMP. Ideal for Professional use, like Redundancy, Distribution & Monitoring, these are currently
the best value for money.
