GSM Dual Amplifier Booster/ Combiner
CCI Model Number DAB-1819-100 & DAC-1819-100
USER’S GUIDE
The CCI GSM Dual Amplifier-Booster Module (DAB) consists of two linear power
amplifiers with intermodulation level control circuitry, each capable of generating a
100-120 Watt GSM signal. The Dual Amplifier-Combiner Module (DAC) is identical
to the DAB Module with the exception of a power hybrid combiner at the output
which combines both signals to provide two 50-60 Watt GSM signals on a common
output.
The following instructions should be followed when installing the unit in service:
· Apply a 28VDC input voltage to the DC Input connector of the Dual Amplifier-
Booster/Combiner Module.
· Insure that the DC Source is capable of delivering up to 15 Amps at 28VDC.
· Apply a GSM signal of up to +41dBm to each RF input port of the Dual
Amplifier-Booster/Combiner Module.
· The Dual Amplifier-Booster/Combiner Module will provide approximately
10dB or less of RF Gain.
· Check the RF output to insure the proper output power is present.
(Approximately 100-120 Watts).
· Adjust the input power level to insure the output power level is in compliance
with the values indicated in the table on page 2.
· Install the Alarm Connector to the Alarm Output connector of the Dual
Amplifier-Booster/Combiner Module.
Setting the RF Output Power on the DAB & DAC Booster Amplifier
The RF output power is not adjustable on the DAB & DAC Booster Amplifier. The
user must adjust the RF input power to the Booster Amplifier such that the RF output
power level does not exceed the levels shown below in order for the RF output
spectral emissions to be compliant with the FCC spurious emissions limit of -13 dBm
outside of the assigned frequency block. These levels must not be exceeded.

This equipment complies with Part 24 of the FCC rules. Any changes or
modifications not expressly approved by the manufacturer could void the user's
authority to operate the equipment.
In order to comply with FCC rules for RF exposure, it must be observed that the
antenna connected to this equipment be fixed on an outdoor structure and that it
must have a minimum separation distance of 2 meters between it and any
person."
