1. INTRODUCTION
The Repeater assembly provides exceptional repeater performances to extend the
coverage area of radio communications in buildings and RF shielded environments.
Features such as high linearity power amplifiers are contributing for the overall
improved system linearity performances. The unit is based on a duplexed path
configuration, having sharp out of band attenuation filters to improve the isolation
between the receiving and transmitting paths. In addition the unit consist of SAW filter
in each path for better spectrum purity.
The following are some of the features of the Dekolink Repeaters:
• 4W composite output power
• 90 dB RF gain
• Flexible software controlled Band Pass Filter center frequency
• Relatively small dimensions
• Local and remote (optional) monitor and control (software enabled)
• High spectral purity

3. BLOCK DIAGRAM
Figure 1: Repeater RF Block Diagram
The block diagram showed in figure 1 illustrates the overall functionality of Dekolink
iDEN Repeater. Dekolink’s programmable iDEN Repeaters employ advanced
up/down conversion Intermediate Frequency (IF) Surface Acoustic Waves (SAW)
filtering architecture. This new technology offers distinct advantages over conventional
repeaters, when high adjacent selectivity and spectrum purity is required.
The Channeler Module (blue colored) consists of dual Radio Frequency (RF) Up/Down
Converter sub-modules for Downlink and Uplink paths. The Channeler amplifies the
received RF signals and converts them into an intermediate frequency (IF). The IF
outputs are connected to a SAW Filter. The IF outputs are converted back to the
original RF frequencies.
Cellular modem is an option for remote monitoring and control repeater parameters.

4.1.1.Components Description
The following is a description of the main components of the Repeater.
4.1.2.Channeler
The Channeler Module consists of dual Radio Frequency (RF) Up/Down Converter sub-
modules for Downlink and Uplink paths. The Channeler amplifies the received RF
signals and converts them into an intermediate frequency (IF). The IF outputs are
connected to a SAW Filter. The IF outputs are converted back to the original RF
frequencies. The Channeler also has controllable attenuators (32 dB range in steps of
1dB)and a pre-amplifier for each path.
4.1.3. Repeater Monitor Module
The Monitor Module measures the current of the following elements of the Repeater:
Up/Down Converter, Uplink Power Amplifier, and Power Supply. It also senses the
Downlink output power. If a module fails, an appropriate report is sent to the Control
Box and the Summarized alarm red LED lights up.

REPEATER OVERVIEW
Dekolink™—IDEN Repeater Hardware Manual 9
4.1.4. Control Box
The Control Box is used to control and monitor all modules in the Repeater. It also
provides local or remote connection to a PC. (See Dekolink’s RMT User Guide for
more information.)
4.1.5. Power Supply
The power supply module has a wide range of allowed input power.
The output power provided to the repeater internal modules is 28VDC, 9VDC and
15VDC.
4.1.6. Duplexers
The duplexers isolate the transmit path from the receive path. The pass bandwidth of
the duplexer is the entire width of the Uplink band and the Downlink bands
respectively.
4.1.7. Power Amplifiers
The power amplifier is the final stage of both the Downlink and Uplink paths. The
Repeater includes Power Amplifiers with relatively high Third Order Intercept Point
(IP3) figures, thus allowing high output power while preserving high linearity of the
output signals.

5. REPEATER FEATURES
5.1. Monitor And Control
The Dekolink Repeater Monitor Module monitors the DC functioning (DC Current and
Voltage Measurement) of the Repeater and provides local summarized feedback by an
alarm LED. The module provides the alarm statuses to the Control Box in the repeater. The
Control Box detects faults and controls the Repeater functions. The RMT software handles
alarm reporting and parameter transmissions to the repeaters’ outside world.
These functions are monitored and controlled in two ways:
• By an external PC through a serial interface connector on the Control Box.
• By a remote connection via a modem connected to the Control Box serial
interface. (Optional)
• The repeater operates from a power source of 110V/220 VAC. The maximum
consumption power is 120W
5.2. SALC (Smart ALC) Function
The Smart ALC optimizes gain factors while enabling iDEN repeater to remain
“transparent” to the network (both to the base stations and the mobile units).
Uplink and downlink balance is preserved. In previous repeaters there are separate
adjustments for the uplink and downlink. Here there is just one adjustment, manual
or automatic to both channels. Both channels have to be balanced for the proper
seamless integration of the repeater in the network. Unbalanced operation bares the
risk of reducing the dynamic range of the base station itself.
Reduction of isolation problems: .The proposed repeater will not oscillate.
Whenever the isolation drops for some reason the repeater will automatically sense
the oscillations and automatically reduce the gain in accordance with the new
isolation conditions. Once the isolation problem is solved the repeater will
automatically raise the gain again. All this is remote monitored and if so desired
remote controlled.

REPEATER FEATURES
Dekolink™—IDEN Repeater Hardware Manual 11
No adjustments are required: When installing the repeater, the standard procedure
for the technician is to tune the repeater to the desired isolation and gain values.
With SALC, the tuning procedure is accomplished automatically, thus saving
precious workmanship and equipment usage time for a “plug & play” foolproof
deployment.
The SALC periodically learns traffic conditions, avoiding the need to remember and
store the last state after power failure. Repeaters that blindly amplify the pilot code
(minimal transmission) of a certain base station might generate network problems
(unnecessarily increase the noise in a certain cell). By keeping the same gain for
pilot only transmissions as well as for full traffic situations, the Dekolink SALC
feature minimizes this effect.
SALC Summary, Conventional iDEN repeaters often interfere in the network when
strong traffic raises the repeater input signal level, which as a result turns on the
ALC algorithm of the system. Once under ALC, the conventional system is no
longer in its linear dynamic range, hence creating interferences in the cell shrinking
or expanding procedures. The Smart ALC solves this problem and thus there is no
need for adjustments. The repeater will not interfere with the network shrinking or
expanding processes and thus become “network friendly “.
5.3. Automatic Level Control (ALC) Function
The repeater has ALC functioning on both the Uplink and Downlink power amplifiers
that prevents saturation of the power amplifier. The amplifier has a directional coupler
and a detector that monitors the output power. When a high signal is received, the ALC
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 that the power amplifier operation stays within
the linear region only, thus preventing saturation and signal distortion.
Automatic Level Control protects the amplifiers from overloading and prevents the
system from generating spurious emissions. ALC limits the output power to a constant
value (Maximum output power). The output power is sampled, decoupled, rectified and
used to control the attenuator network in the RF modules.

5.4. RF Gain Setting
The gain range is 59-90 dB and should be set via the RMT software according to the
received power at the Base/Donor antenna, required Output Power at Mobile antenna
and Isolation requirements. Use the Max Gain field for Downlink GAIN setting and the
Gain Delta fields to determine the GAIN difference between Uplink and Downlink path
(Uplink GAIN follows Downlink GAIN by “Delta” dB).
Note: When you set the gain to 60 dB the Maximum Output Power will degrade
due to overload input power the maximum input power you can inject is
–35 dBm.
It is recommended to set the Downlink path gain to a maximum of 12 dB below the
isolation between the Base antenna and the Mobile antenna.
