I2ODPA4040GPCS Dual Amplifier Booster/Combiner

350 West Java Drive Sunnyvale, CA. 94089 USER’S MANUAL GSM Dual Amplifier Booster/ Combiner REMEC Model Number xxxxxxxxx GSM Booster User’s Guide Page 1 of 3 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 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 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. 350 West Java Drive Sunnyvale, CA. 94089 USER’S MANUAL GSM Dual Amplifier Booster/ Combiner REMEC Model Number xxxxxxxxx GSM Booster User’s Guide Page 2 of 3 • 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.) 2.

Amplifier ON Amplifier OFF Per your request we have provided two plots one with the amplifier on and the second plot with the amplifier off. This is to show that the second harmonic is the only emission being produce by the amplifier and that the amplitude levels display on the analyzer, that are over the limit, is do to the lack of the dynamic range of the analyzer due to the high external attenuator. Also, the plots in the application (FCC ID: E675JS0039) from 5.5 GHz to the second harmonic were measured with a RBW and VBW of 30 kHz. We measured with a RBW and VBW of 1 MHz, per the rules, putting the noise floor of the analyzer above the limit. The only way to show that the noise of the analyzer will be in compliance will be to reduce the RBW down to either 30 kHz or 10 kHz, but this will be deviating from the rules. In the past I have provided two plots, one with the unit on and another with the unit off, to show FCC that the levels over the limit where not being created or produce by the device under test, but it was due to the lack of dynamic range from the spectrum analyzer itself.
