REMEC’s PCS Edge-GSM Dual Power Amplifier Model DPA-4040E 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 Edge or GSM modulated 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 2- 
carrier 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 DPA-4040E 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-4040E 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 
(AMM) 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, consuming

6RU of height in a 19-inch rack. 

 
The following instructions should be followed when installing the unit for service: 
 

1. Installation Instructions 
 

1.1  Apply a 27VDC input voltage to the DC Input connector of the DPA-4040E 

 

1.2  Ensure that the DC Source is capable of delivering up to 25 Amps at 27VDC. 

 

1.3  Apply either an Edge or GSM modulated signal to each RF input port of the DPA-4040E. 

 

1.4  Measure the RF output port to ensure the proper output power is present.
