OPERATING INSTRUCTIONSSPA9325-30Note: These operating instructions describe the procedure for turning on and off the amplifieroutput power using signal generators. This amplifier will be used with transmitters which have beenor will be certified separately. The specific transmitter instruction book should be consulted for thecorrect method to use this amplifier with transmitters.1. The input voltage range, applied to pin A1 of the DC input connector, should be between –36VDC and–57 VDC. Pin A2 and A3 of the connector should be grounded.2. Pin 5 of the Data I/O connector should be grounded to enable operation of the amplifier without thedata interface. Pins 1, 2, 11, and 12 on the Data I/O connector are connected to ground. Operationwith the Data I/O interface can only be performed using the transmitter software. See the transmittermanual for instructions.3. Connect the RF signal generator to the RF input port.4. Connect the RF output port to the measurement equipment. Make sure the measurement equipment iscapable of handling 30 watts, or use a power attenuator or directional coupler to attenuate the signal toa level the equipment can handle.5. To turn on the amplifier, first apply the DC voltage with the specified range (-48 VDC nominal).6. Apply RF power from the signal generator. Adjust the RF input power until the desired RF outputpower is achieved. The amplifier’s maximum RF output power rating is 30 watts (+44.8 dBm)7. The gain may change up to 0.5 dB as the amplifier temperature stabilizes after turn-on. Let theamplifier warm up for 10-30 minutes, then re-adjust the power to compensate for the gain change.8. The amplifier is now operational.SPECIFICATIONSParameter SpecificationOperating Frequency 1930 to 1990 MHzRated Output Power +44.8 dBm (30 Watts)Gain at Full Power 48 +/- 1 dBInput Voltage Range -36 to –57 VDCMaximum DC Power Consumption 220 WattsChanneling Controlled by transmitterModes of Transmission GSM (Gaussian Minimum Shift Keying)Type of Modulation Not applicable (performed by transmitter)Occupied Bandwidth and Emissions DesignatorsEmissions Type Amplitude Frequency Removed from CarrierGSM (300KGXW) -30 dBc 200 kHz-33 dBc 250 kHz-60 dBc 400 kHz-70 dBc 600 kHz-73 dBc 1200 kHz-75 dBc 1800 kHz-80 dBc 6000 kHz
