USER’S MANUAL
GSM Dual Amplifier Booster/ Combiner
REMEC Model Number xxxxxxxxx
User Manual
REMEC’s GSM Dual Power Amplifier (GDPA) product consists of two low gain power amplifiers
and a power combiner integrated into one compact housing capable of amplifying and / or
combining one or two PCS 1900 GSM RF carriers.
Two supplied user jumper cables allow the user to combine the 2 independent and isolated RF
radio carriers into one common output port via the integrated power combiner. This option
reduces the available output power for each RF carrier to 46 dBm per carrier, or a composite 2carrier power of 49 dBm. This mode of operation is noted as Combined Output Mode.
The user has the option of removing the jumper cables and connecting directly to the two
independent isolated output connectors of the Dual Power Amplifier. In this configuration, the
output power for each output port is 49.5 dBm separately. This mode of operation is noted as
Isolated Output Mode
The GDPA has factory configurable gain only, so input power adjustments must be made by the
user in order to adjust the output power.
This product has integrated DC power-conditioning circuits, monitoring circuits, control circuits,
digital interface circuits and fans. The available monitoring, control circuitry, and digital interface
circuits can be factory configured to meet customer needs of capability and cost flexibility.
The GDPA is a piece of a larger product solution that allows for up to 6 GPDA’s to be placed in
a common shelf side by side in a 19 inch Rack. The larger product solution consists of an AC to
DC power rectifier and a cable kit to interface input signal, output signal, AC and DC power to
OEM radio equipment. The larger product solution has an optional amplifier monitoring
assembly that can interface to OEM base station alarms or local monitoring by means of a
graphical user interface (GUI). The entire larger product solution is space efficient taking up
6RU high in a 19-inch rack.
The following instructions should be followed when installing the unit for service:
1. Installation Instructions
• Apply a 28VDC input voltage to the DC Input connector of the GDPA
• Ensure that the DC Source is capable of delivering up to 17.6 Amps at 28VDC.
• Apply a GSM signal to each RF input port of the GDPA.
• Measure the RF output port to ensure the proper output power is present.

• Adjust the input power level to ensure the output power level is in compliance with the values
indicated in Table 1 or Table 2 depending upon the mode of operation (Combined or Isolated).
(Note : The user must adjust the RF input power to the Booster Amplifier such that the RF
output power level does not exceed the FCC certified power levels. The FCC certified power
level is determined by the RF output spectral emissions to be compliant with the FCC spurious
emissions limit of -13 dBm outside of the assigned frequency block. Near the block edges, the
GMSK signal is such that the output power level must be further reduced so that the -13 dBm
spurious level is not exceeded.) (These levels must not be exceeded for FCC compliance.)

4. Tune-Up Procedure
There are no user tunable components in the design so no Tune-up procedure is required.
5. FCC Part 24 compliance
Changes or Modifications, not expressly approved by the manufacturer, could void the user's
authority to operate the equipment.
FCC rules for RF exposure require that the antenna connected to this GDPA equipment is fixed
on an outdoor structure with a minimum separation distance of 2 meters between it and any
person.
