1.3 Purpose
The full band repeater CSR-DMT is a bi-directional digitally controlled amplifier that offers an increase of
signal strength in small and medium-sized rooms.
Generally TETRA repeaters are used in emergency services and government systems to provide signal
coverage for areas with poor or no signal (e.g. blind spot). Procom A/S came across the insufficient
coverage within buildings, airports, tunnels, etc. The digital repeater CSR-DMT series can solve these
problems by amplifying the available signal from an outdoor antenna into weak coverage areas via an
antenna or indoor delivery network with multiple antennas.
CSR-DMT is based on a digital filtering approach thanks to that the CSR-DMT is very flexible in
continuously changing conditions of mobile communication systems. The digital filter can be reconfigured
in a custom desired way:
•
Full band (5 MHz) is default configuration (factory settings)
•
Additionally it is possible to adjust bandwidth and center frequency of band-segment
•
Possible number of band-segments is 1-4
•
adjustable gain of individual band-segment
Built-in Automatic Gain Control circuit prevents the occurrence of undesired oscillations, signal
compression and distortion conditions.
