Teko Telecom Digital Donor Front End•
The Digital Donor Front End Module is the single-band/single-operator System RF interface
towards a Donor Antenna. No physical connections are required between the DFE and the
cellular network: the Donor Antenna provides the connection to a BTS or NodeB over an air
link.
Coverage Systems can be equipped with one or more Donor Front End modules to make
multiple congurations available: single operator (single band / multi-band) and multi-
operator (single-band / multi-band).
SIRIUS: Teko Telecom Modular Coverage and Capacity System
A single-band single-operator modular O-air Repeater can be set up combining a Digital
Donor Front End Module and a Service Front End (Teko Telecom single-band/multi-operator
interface towards a Service Antenna). Up to 4 Donor Front End Modules can be connected to
a single Service Front End to provide a single-band 4-operator modular O-air Repeater.
Digital Donor Front End Modules can also be used to drive Optical Systems: the Digital Donor
Front End Module allows Optical Systems to be driven without the need of a dedicated BTS or
Node B. A donor antenna picks-up the signal and the Optical System acts as a repeater with
distributed Service antennas connected to the Remote Units. Service Front End subracks can
be connected to DFE modules to provide coverage to the area next to the Master Unit site.
Doc ID Number 91 080 0781 - Rel. 02

www.tekotelecom.it
www.tekotelecom.it
Let us repeat !
Each DFE module hosts the duplexer, to be connected to the Donor Antenna to separate/
combine downlink and uplink paths.
In downlink the signal from the Donor Antenna is preamplied by a Low Noise Amplier and
converted into an IF signal by a downconverter. The selection of the band of frequencies or
channels to be extended is handled by a digital lter.
The digital lter can manage 1 variable band or 2 variable sub-bands.
An upconverter converts the IF signal into the RF output signal.
In uplink the signal from the Service Front End Subrack or from the Optical System is converted
into an IF signal by a downconverter, ltered and re-converted into an RF signal, amplied by
a power amplier and re-transmitted to the signal source.
