3.2 COMPONENTS GENERAL DESCRIPTION
A description of the main components of the Digital Repeater follows.
3.2.1 Channeler
The Channeler Module consists of the dual Radio Frequency (RF) Up/Down
Converter sub-modules for Downlink and Uplink paths.
The Channeler amplifies the input RF signals and converts them into an intermediate
frequency (IF). The IF outputs of the Channeler are routed to the Dekolink Digital
Filter (DDF) modules.
In the DDF, the IF inputs from the Channeler are converted back to their original
frequencies. The Channeler also includes digital controllable attenuators (range 32
dB, in steps of 1 dB) and a pre-amplifier for each path.
3.2.2 Monitor Module
The Monitor Module monitors the Repeater operation and provides a visual warning
whenever it detects a failed module or function. The monitoring is performed by
measuring the current of several elements:
DDF Uplink and Downlink, •
•
•
•
Up/Down Converter,
Uplink Power Amplifier, and
Power Supply.
If a module fails, the appropriate red LED lights up and a report is forwarded to the
Control Box.
For a more detailed description of the module, refer to paragraph 3.3.
3.2.3 Controller
The Controller (also called Control Box) controls and monitors the parameters in all
modules of the Repeater. It provides local or remote connection to a PC (See
Dekolink’s RMT User's Guide for more information.).
For a more detailed description of the module, refer to paragraph 3.3.
3.2.4 Digital Filter Module
Dekolink’s Digital Filter Module uses digital processing techniques to generate up to
eight separate, programmable, and independent filters. These filters are activated in
both the Downlink and the Uplink paths.
The filter parameters can be modified and tailored to meet the customer’s specific
applications requirements.
3.2.5 Connections Box
The Connections Box module interconnects the Repeater Modules. This box includes
the Repeater ON/OFF switch and the power fuses.
