1. INTRODUCTION
1.1 GENERAL
Dekolink’s Mini Repeaters are high selectivity amplifiers that amplify signals
bi-directionally between base stations and mobile handsets, in cellular and other
wireless systems.
Dekolink’s Mini Repeaters provide high selectivity capability by employing an
advanced up/down conversion and Intermediate Frequency (IF) Surface
Acoustic Waves (SAW) filtering architecture. This advanced architecture
offers distinct advantages over conventional band selective Repeaters.
These Mini Repeaters feature a "plug-and-play" capability for fast response and
immediate solution to your coverage needs. These repeaters can be operational
flexible by adding the optional SAW Switcher which enables to set one of two
of two pre-determined different frequency bands, thus providing two units in
one Repeater.
1.2 APPLICATIONS
Dekolink’s Mini Repeaters are highly suitable for deployment in dense urban
environments, tunnels and other areas where physical structures cause low field
strengths. These Mini Repeaters introduce new system capabilities that enable
a wide variety of applications particularly when adjacent band selectivity and/or
very high spectral purity are required. The Repeaters provide 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, and can perform
as hole-filler in particular spots in a residence such as parking lots, tunnels, etc.
1.3 DESCRIPTION
Small, lightweight and easy-to-install, this Mini Repeater addresses network
coverage problems quickly and straightforwardly (see Figure 1).
1.3.1 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 preventing oscillation in case of insufficient isolation. It prevents “cell
coverage shrinking” while maintaining the power amplifier linearity.
Dekolink’s Mini Repeaters comply with relevant standards in accordance with
their application, such as CDMA 2000, FCC, ETSI, etc.
1.3.2 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

PRODUCT MANUAL MINI REPEATER DEKO2408-09 DEKOLINK WIRELESS LTD.
Page 2 Proprietary Data Pub. 308-2005 Rev. 2.00S
different operation environments or adapt it to the evolving operating
environment.
The Switchable Bandwidth function provides you the capability to set the
Repeater to one out of three pre-determined different frequency bandwidths, as
per requirement. At each frequency band, the operating center frequency can
slide all over the application bandwidth.
This capability lowers operating costs and reduces complex logistics by
removing the need to install a different Repeater at separate locations with
different allocated bandwidth, or similarly, in case the allocated bandwidth
evolves at the installation site, you are not required to replace the installed
Repeater, just set the second bandwidth.
1.4 CONTROLS AND INDICATORS
The High selectivity Mini Repeater includes one power adjustment selector and
three status LEDs in its front panel (see Figure 2).
Figure 1: Mini Repeater
1.4.1 Power Selector
The Power selector enables to set the output power in accordance with the local
requirements, during the setup and during troubleshooting of the Repeater.

2. FUNCTIONAL DESCRIPTION
2.1 GENERAL
The High selectivity 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 isolation between the receiving and transmitting paths.
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 and is first
filtered by the Duplexer. The incoming signal is amplified 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 input IF signal is next filtered by a Surface Acoustic Wave (SAW) filter.
After filtration, the signals are converted to RF signals by the Up-Converter.
This processing path provides sharp out-of-band attenuation that improves the
isolation between the receiving and transmitting paths.

Page 8 Proprietary Data Pub. 308-2005 Rev. 2.00S
2.2.2 Power Monitoring- Smart-ALC
Next, the output RF signal is amplified by a power amplifier and combined by a
duplexer before output.
The power amplifier includes power-monitoring circuits with Automatic Level
Control (ALC). The ALC prevents excessive output power while maintaining
the power amplifier linearity.
The Repeater also includes Dekolink's Smart-ALC algorithm for gain control.
This algorithm adjusts the gain of the Repeater paths in case of insufficient
isolation. This feature prevents oscillation while maintaining gain utilization in
the linear range operation.
To reset the Repeater to its highest gain value, it is sufficient to simply turn the
Repeater power off then on.
2.2.3 SAW Switcher
The SAW Switcher enables you to select one out of three frequency bands in
order to adapt the Repeater to the site bandwidth allocation. The selection is
software enabled (see Chapter 6).
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 also includes protection against high V.S.W.R. and difficult
operation conditions. An auto recovery mechanism returns the unit to normal
operation, after power or other failures.
