1. INTRODUCTION
1.1 GENERAL
Mini-Repeater Deko2119 is a PCS Block Selective RF Mini-Repeater that
amplifies signals bi-directionally between base stations and mobile handsets, in
cellular and other wireless systems (see Figure 1).
Deko2119 provides high selectivity capability by employing an advanced
up/down conversion and Intermediate Frequency (IF) SAW filtering
architecture.
This product features the Smart ALC algorithm that provides "plug-and-play"
capability for fast response and immediate solution to your coverage needs,
while preventing degradation in network performance. This repeater is provided
with a SAW Switcher that can be configured with pre-determined different
frequency blocks so as to enable complex frequency plans, as well as providing
two units in one Repeater.
Mini-Repeater Deko2119 is provided with 80 dB gain as default. Some units
are configured with 70 dB gain only. This manual is valid for both
configurations.
In addition, Deko2119 features a special configuration for dual-band coverage
using a Combiner. It enables interconnecting with another Mini-Repeater, such
as Deko2408, to provide coverage in the Deko2119 bandwidth as well as for
CDMA by Deko2408. The dual-band combination supports a single
Distribution Antenna System to provide coverage by different providers.
Deko2119 fully meets the FCC standard requirements.
1.2 APPLICATIONS
Dekolink’s Mini-Repeaters are suitable for deployment in dense urban
environments, tunnels and other areas where physical structures cause low
cellular coverage.
The Mini-Repeater introduces new system capabilities that enable a wide
variety of applications particularly when adjacent band selectivity and/or very
high spectral purity are required. This repeater provides a solution to situations
in which flexible, high quality and high resolution filtering methods are
necessary.
Dekolink’s Mini-Repeaters help improve in-building coverage, as the driver for
a single antenna for spot coverage or a distributed antenna system (DAS) for
larger coverage areas.

1.4 DESCRIPTION
1.4.1 General
This paragraph provides a brief description of key functional capabilities of
Mini-Repeater Deko2119.
1.4.2 Switchable Bandwidth
The internal SAW Switcher enables to implement the Switchable Bandwidth
option. This function enables more efficient and better adaptability of the
Repeater to your needs. This capability enables you to install the Repeater in
different operation environments or adapt it to the evolving operating
environment.
In standard configuration, the Switchable Bandwidth function provides the
capability to set up to three pre-determined different frequency blocks of 5, 10
and 15 MHz bandwidth respectively, as per requirement. The operating center
frequency is user-adjustable anywhere within the PCS band.
This capability ensures that in case of bandwidth evolution at the installation
site, you are not required to replace the installed Repeater, just set the second
bandwidth.
1.4.3 Smart-ALC
The downlink path includes Dekolink’s Smart Automatic Level Control
(Smart-ALC) control algorithm to ensure linear operation of the Repeater. This
feature automatically adjusts the Repeater gain, reducing it in case of over the
limit power output, or boosting it to maintain maximum gain utilization.
The Smart-ALC automatically maintains downlink and uplink gain balance.
This capability keeps system transparency at all times and enables "cell

Pub. 313-2006 Rev. 2.01S Proprietary Data Page 3
shrinking" whenever applicable. This algorithm is intended to prevent
oscillation in case of insufficient isolation.
In CDMA and UMTS networks, this optimum gain setting ensures the repeater
is transparent in the network and allows the repeater coverage area to “breathe”
along with the main cell coverage.
1.4.4 Operating Modes
Mini-Repeater Deko2119 can be operated in two modes:
•Manually, by a power control selector and LED indicators.
•Software control, via RS-232
1.4.5 Dual-Band Configuration
The Deko2119 can be operated in a dual-band configuration with a DEKO2408
Mini-Repeater. This configuration supports a single Distribution Antenna
System (DAS) to enable dual coverage of the PCS range (by Deko2119) and
the Cellular range by Deko2408.
Deko2119 includes a special purpose diplexer at the input and output interfaces
to enable the dual-band interconnection.
1.5 CONTROLS AND INDICATORS
The Block Selective Mini-Repeater includes one power adjustment selector and
three status LEDs in its front panel (see Figure 2).

2. FUNCTIONAL DESCRIPTION
2.1 GENERAL
The Block Selective Mini-Repeater functional operation is based on a duplexed
path configuration. In each path, the signal is down-converted to an
Intermediate Frequency (IF); filtered by a Surface Acoustic Wave (SAW) filter
and up-converted back. This configuration gives sharp out of band attenuation
for improved system performance.
2.2 FUNCTIONAL DESCRIPTION
2.2.1 Signal Path
The following process is performed in both the Uplink and Downlink paths of
the Repeater (see Figure 3).
The incoming RF signal from either the Base antenna (from the BTS) or from
the Mobile antenna (from the mobile handset) enters the Repeater through a
diplexer that enables dual-band support. The signal is filtered by the Duplexer,
followed by an Automatic Gain Control (AGC) amplifier (AMP). The signal is
then down-converted to an Intermediate Frequency (IF).
Figure 3: Mini-Repeater - Block Diagram
The IF signal is further filtered by a Surface Acoustic Wave (SAW) filter. The
Mini-Repeater includes three selectable SAW filters. However, a single filter
can be activated at any time. The IF signal is then converted back to RF signal
by the Up-Converter. This processing path provides sharp out-of-band
attenuation that improves the isolation between the receiving and transmitting
paths.

PRODUCT MANUAL MINI-REPEATER DEKO2119 DEKOLINK WIRELESS LTD.
Page 8 Proprietary Data Pub. 313-2006 Rev. 2.01S
The output RF signal is amplified by a power amplifier, combined by the
Duplexer and output from the diplexer that enables dual-band (Cellular and
PCS) signal output.
2.2.2 Power Monitoring - Smart-ALC
The Smart Automatic Level Control (Smart-ALC) is an innovative algorithm
for automatic repeater gain adjustment. Combined with advanced control
algorithms, SALC can perform gradual learning of traffic load characteristics
and adjust the Repeater RF Gain to the desired value.
This automatic operation practically removes the need to make initial settings
for maximal traffic load conditions and eliminates the need for numerous site
visits to take care of Gain adjustment.
The Smart-ALC maintains the Uplink/Downlink gain balance for system
transparency. This algorithm also adjusts the gain of the Repeater paths in case
of oscillations that may occur due to insufficient isolation, thus preventing
oscillations while maintaining the gain in a linear range operation. Smart-ALC
effectively reduces isolation problems.
To reset the Repeater to its highest set gain value, it is sufficient to simply
disconnect the Repeater power cable for several seconds and reconnect anew.
In addition, the power amplifier includes power-monitoring circuits with
Automatic Level Control (ALC). The ALC prevents excessive output power
while maintaining the power amplifier linearity.
2.2.3 SAW Switcher
The SAW switcher enables to select one or two PCS operational blocks along
the PCS band. The desired pair of frequency blocks can be tuned anywhere in
the available band. The selection is software enabled.
2.2.4 Control and Monitoring
The Mini-Repeater operation is controlled by a microprocessor. The processor
monitors the Repeater function and controls the alarm LEDs located on the
Mini-Repeater front panel.
2.2.5 Protection
The Mini-Repeater includes protection against high V.S.W.R.
An auto recovery mechanism returns the unit to normal operation, after power
or other failures.
