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.

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.

8 Installation of the Repeater in Lab.
NOTE! In case that Antennas are not connected, terminate the Base & Mobile marked
connectors with a 30dB attenuator, in order to prevent damage (by a regressing signal) to
protect the Test equipment.
The attenuators power rating should be at least 50W at the Mobile marked repeater’s
terminal, and 10W at Base marked repeater’s terminal.
- Connect power supply. A supplied voltage in the range of 90 to 260VAC should be
connected to the repeater’s AC power connector.
- Inject to the repeater’s Downlink route terminal (Base connector), RF Signal from the
connected RF Generator, and a Spectrum Analyzer, to the repeater’s Mobile terminal,
and test the repeater RF performance (see test set up diagram below).

REPEATER (BDA) OPERATION
The RF connection is made via two type “N” female connectors. The RF connector labeled
“Base” must be connected to the antenna pointing to the base station; usually a rooftop antenna.
The RF connection labeled “Mobile” must be connected to the antenna pointing into the area to
be covered by the Repeater such as inside a building or outdoor shaded area.
The repeater operates from 110V/220 VAC @ 2A.
9.1 AGC (ALC) FUNCTION
The repeater has AGC (Automatic Gain or Level Control) function on both paths that serve to
prevent the saturation of the power amplifier. The amplifier has a directional coupler and a
detector at the output of the high power amplifier to monitor the output power. When a high
signal is received the automatic level control detects the amplitude and sends a feedback signal to
a voltage variable attenuator that attenuates the signal level so that the output power of the
amplifier does not exceed the preset limit. This level control ensures the power amplifier
operation in the linear region only.
9.2 RF GAIN SETTING
For proper operation of the Repeater, the isolation between the base station antenna and the
mobile antenna should exceed the Repeater gain by at least 10 dB. If the Repeater gain is higher
than the isolation between the antennas, oscillation will build up and will saturate the amplifier.
The step attenuator on the low noise amplifier can reduce the Repeater gain. The repeater gain
can be reduced by 31 dB in 1 dB steps.

Manual
10 BDA INSTALLTION
Install the BDA Repeater in a shielded, ventilated and easy to reach area.
Use low loss cables to connect antennas to the BDA. Install the BDA close to the service area to
improve output power and noise figure.
The BDA Base/Donor connector port is connected to donor antenna, usually a Yagi antenna,
while the BDA Mobile/Remote connector port is connected to a mobile antenna; outdoor indoor.
10.1 BASE / DONOR ANTENNA INSTALLTION
Typically this is a directional antenna such as Yagi or Dish antenna of 10 to 15 dB gain. This
antenna is pointed to the base station to get maximum input power. This antenna should be in
line of sight with the base site. Raise this antenna higher if no line of site is achieved. The
required Base signals should be the dominant signals; at least 6 dB higher power than other
signals.
Choose the antenna site to get the maximum isolation from the remote (mobile serving) antenna.
10.2 REMOTE / MOBILE ANTENNA INSTALLTION
The second antenna is connected via cable that has typical 1~10 dB attenuation (depends on the
length of the cable) to the CBDA MOBILE port. This type of antenna is omni directional
(isotropic), or wide beam, with 0 to 2 dBi typical gain and is installed and distributes indoor (in
buildings, tunnels, basements, park lots, shopping centers etc.). Typical specifications: gain: 2
dBi, VSWR: better than 2:1, Impedance: 50 ohm. For direct connection to the BDA this antenna
must be installed to provide a minimum separation distance of 2 m (200 cm) from persons
within the area.
Less separation is needed if the power from this power is divided into many antennas covering
many floors or areas.
Page 13 of 21
IDEN Digital Repeater Installation
Manual
10.3 ANTENNA ISOLATION
For proper operation the isolation between these two antennas must be at least 10 dB higher than
the BDA gain. Lower isolation would lead to high in-band ripple.
Oscillations will build up when the isolation is lower than BDA gain.
The isolation between the antennas is critical for high gain outdoor repeaters.
To measure the isolation, inject a known signal into one antenna and measure the coupled output
at the other antenna. This should be done across the frequency range of both uplink and downlink
bands.
Page 14 of 21
IDEN Digital Repeater Installation
Manual
11 INSTALLATION STEPS
1. Install all antennas and connect them to the BDA inputs.
2. Set “MAX Gain” according to isolation (at least 15 dB lower) and available donor power.
This allows the SAGC to smartly limit the output power of the BDA.
Optional: The SAGC on the Downlink path guarantees constant downlink power (relative to
cell traffic) when and if the Donor power changes.
3. Uplink will set ultimately according to the downlink gain.
4. Check that the uplink FWD power, if power is at constant maximum then isolation between
antennas is low (BDA oscillations) or the BDA is faulty. In such a case:
• Disconnect one of the cables from the BDA connectors and connect a load at the connectors.
FWD power is at constant maximum
If the

antennas is low. Either improve the isolation (e.g. increase separation) or reduce BDA gain.
• To reduce gain, reconnect the antenna cables. Reduce the

. Reduce the gain further by 10 dB.
then the BDA is faulty (oscillating) and
then the isolation between the donor and remote

12 RF EXPOSURE WARNING
In order to satisfy the FCC RF exposure requirements, you must ensure that the installation
complies with the following:
One antenna is connected via cable that has typical 1~10 dB attenuation (depends on the length
of the cable) to the BDA base port. This antenna is installed outdoor and has very sharp beam
(Yagi type or similar) pointed to the donor (BTS). This type of antenna has about 10dBi gain.
Typical specifications: gain: 8 dBd (=10.1 dBi), VSWR: better than 1.5:1, Impedance: 50 ohm.
The outdoor antenna must be installed to provide a minimum separation distance of 1 m (100
cm) from persons within the area.
The second antenna is connected via cable that has typical 1~10 dB attenuation (depends on the
length of the cable) to the BDA MOBILE port. This type of antenna is omnidirecttional
(isotropic), or wide beam, with 0 to 2 dBi typical gain and is installed and distributes indoor (in
buildings, tunnels, basements, park lots, shopping centers etc.). Typical specifications: gain: 2
dBi, VSWR: better than 2:1, Impedance: 50 ohm. For direct connection to the BDA this antenna
must be installed to provide a minimum separation distance of 2 m (200 cm) from persons within
the area.
Less separation is needed if the power from this power is divided into many antennas covering
many floors or areas.
