3 Introduction.
Dekolink Wireless channel selective repeaters employ digital processing techniques to
attain versatile programmable filter array.
The input RF signal is sampled and converted to digital signals. The digital signal is
filtered using fast parallel logic. Using digital processing techniques the system
generates up to 8 (12 optional) separate, programmable and independent filters. The
filter parameters can be easily modified and tailored to meet specific customer
requirements.
3.1 Computer Program.
Repeater Management Software (RMA) supplied with the repeater and provide full access to
all control setting and monitoring capabilities. The RMA software can be installed on
Windows 95, Windows 98, Windows 2000 & Windows XP operation systems.
Dekolink's Repeater Management Application software (RMA) is used to manage and
control the repeater by local connection via RS232 or remotely by Modem.
3.2 Programmable Modules
All Repeater settings made trough Controller unit (CB-04), This unit controls the active
components in the repeater, and communicate with two DDF (Dekolink Digital Filter) units
Up& Downlink trough RS232 Communication.
The controller controls RF Gain, Power On/Off, AGC On/Off & provides Alarms Report .
The controller also set DDF parameters to each DDF units (Uplink & downlink) it sets
Center Frequency, Bandwidth & Enable/Disable each one of the 8 channels separately of the
Uplink/ Downlink path. It allows independence shaping of several filters, by controlling
frequency, frequency bandwidth and type.

Figure 1: Digital Repeater RF Block Diagram.
Dekolink Wireless channel selective repeaters employ digital processing techniques to attain
versatile programmable filter arrays in both the uplink & downlink paths.
The RF signal entering the repeater, is filtered by a duplexer, amplified, down converted &
sampled to digital signals. The digital signal is filtered using fast parallel logic.
Using digital processing techniques, the system generates up to 8 separate, programmable
and independent filters.
After filtration is accomplished, the digital signals are up-converted to an RF signal,
amplified by a High Power Amplifier & combined by a duplexer to the output port.
