DPA-4040G User Manual
REMEC's PCS GSM-EDGE Dual Power Amplifier Model DPA-4040G product consists of two
power amplifiers and a power combiner integrated into one compact housing capable of
amplifying and / or combining one or two PCS 1900 GSM or EDGE modulated RF carriers.
GSM Modulation
For GSM modulation, 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 2- carrier power of 49 dBm. This mode of operation is noted as
Combined Output Mode.
For GSM modulation, 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
EDGE Modulation
For EDGE modulation, 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 43 dBm
per carrier, or a composite 2- carrier power of 46 dBm. This mode of operation is noted as
Combined Output Mode.
For EDGE modulation, 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 46.5 dBm separately. This mode of
operation is noted as Isolated Output Mode
The DPA-4040G 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 DPA-4040G is a piece of a larger product solution that allows for up to 6 DPAs 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 Module
