USER’S GUIDE
Product Description:
DAC-1819-125-G3 Dual Amplifier Booster/ Combiner:
The CCI GSM Dual Amplifier-Booster Combiner Module (DAC) consists of two linear
power amplifiers with intermodulation level control circuitry, each capable of
generating a minimum 125 Watt GSM/EDGE signal. The Dual Amplifier-Combiner
Module (DAC) contains a passive hybrid combiner at the output which combines
both signals to provide a minimum two 62 Watt GSM/EDGE signals on a common
output.
Operation Description:
The DAC-1819-125-G3 Dual Amplifier Booster/ Combiner is designed to supply a
nominal output power level of 62 Watts (48 dBm) per channel. Although the gain of
the Dual Amplifier Booster/ Combiner is fixed, the output can be adjusted by setting
the input power level.
Operation and Installation Instructions:
The following instructions should be followed when installing the unit in service:
• Apply a 26-30VDC 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 30 Amps at 28VDC.
• Apply a GSM/EDGE signal of up to +40dBm to each RF input port of the Dual
Amplifier-Booster/Combiner Module.
• The Dual Amplifier-Booster/Combiner Module will provide approximately 9dB
or less of RF Gain.

• Check the RF output to insure the proper output power is present.
{Approximately 62 Watts (48dBm) per channel}.
• 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 DAC-1819-125-G3 Booster Amplifier
The RF output power is not adjustable on the PCS DAC Booster Amplifier. The user
must adjust the RF input power to the PCS DAC 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. The
total composite output power at the antenna terminal output of the device
must not exceed the peak output power of 125.9W.

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 10 meters between it and any
person."
