NT3DAB-C-1819Amplifier

GSM Dual Amplifier Booster/ Combiner CCI Model Number DAB-1819 & DAC-1819 USER’S GUIDE The CCI GSM Dual Amplifier-Booster Module (DAB) consists of two linear power amplifiers with intermodulation level control circuitry, each capable of generating a 55-60 Watt GSM signal. The Dual Amplifier-Combiner Module (DAC) is identical to the DAB Module with the exception of a power hybrid combiner at the output which combines both signals to provide two 27-30 Watt GSM signals on a common output. The following instructions should be followed when installing the unit in service: • Apply a 28VDC input voltage to the DC Input connector of the Dual Amplifier- Booster/Combiner Module. • Insure that the DC Source is capable of delivering up to 15 Amps at 28VDC. • Apply a GSM signal of up to +39dBm to each RF input port of the Dual Amplifier-Booster/Combiner Module. • The Dual Amplifier-Booster/Combiner Module will provide approximately 10dB or less of RF Gain. • Check the RF output to insure the proper output power is present. (Approximately 55-60 Watts). • Adjust the input power level to insure the output power level is in compliance with the values indicated in the table on page 2. • Install the Alarm Connector to the Alarm Output connector of the Dual Amplifier-Booster/Combiner Module.

The user must adjust the RF input power to the Booster Amplifier such that the RF output power level does not exceed the levels shown below in order for the RF output spectral emissions to be compliant with the FCC spurious emissions limit of -13 dBm outside of the assigned frequency block. These levels must not be exceeded. Block Channel Center Frequency (MHz) Maximum RF 0utput (Watt) A 1930.2 5 A 1930.4 - 1944.6 55 A 1944.8 5 D 1945.2 5 D 1945.4 - 1949.6 55 D 1949.8 5 B 1950.2 5 B 1950.4 - 1964.6 55 B 1964.8 5 E 1965.2 5 E 1965.4 - 1969.6 55 E 1969.8 5 F 1970.2 5 F 1970.4 - 1974.6 55 F 1974.8 5 C 1975.2 5 C 1975.4 - 1989.6 55 C 1989.8 5 This equipment complies with Part 24 of the FCC rules. Any changes or modifications not expressly approved by the manufacturer could void the user's authority to operate the equipment. In order to comply with FCC rules for RF exposure, it must be observed that the antenna connected to this equipment is fixed on an outdoor structure and that it must have a minimum separation distance of 2 meters between it and any person."

Response to TCB findings FCC ID: NT3DAB-C-1819 Hi Davida, The following issues were identified after our review of the application: 1. “/” is not an allowed character in an FCC ID. Please provide a new FCC ID and all associated paperwork changed to the new ID. Response – Revised form 731 supplied. 2. Please confirm that there are no configurations were one antenna output could exceed the 24.232 100 watt limit. We need to be clear what “55 watts per channel” means. Response - The equipment is designed for one carrier per output only. There is a configuration where two separate carriers can be fed to two separate input ports on the amplifier and the output signals are passively combined and fed to the antenna. In this case there are two identical amplifiers housed in one single chassis. Two carriers are never fed simultaneously to one amplifier. 3. The power reduction for the first and last channels should be for each block. See 24.238(a). Please modify the test report to reflect this. Response – Revised test report supplied. 4. Please supply the installation manual. Response – Manual supplied. 5. Please provide an exhibit documenting how the installer sets the power level. It should also include information about the restriction to 5W on the highest and lowest channel of each block. Make sure the exhibit lists the highest and lowest power level settings available. Response – See manual. Best regards Barry C.

Technical Description The PCS Cell Booster was specifically designed to integrate with compact GSM base stations without any need for retrofitting the original equipment. The system consists of a 5U 19” rack mount tray, which can accommodate up to five individual modules. The modules include a Dual Amplifier-Booster Module, a Dual Amplifier-Combiner Module, a Triple Duplexer Module, and a Power Supply Unit (PSU). The Cell Booster system can be configured with any combination of the above modules in order to achieve the desired performance results. The Dual Amplifier-Booster Module (DAB) consists of two linear power amplifiers with intermodulation level control circuitry, each capable of generating a 55 Watt GSM signal. The Dual Amplifier- Combiner Module (DAC) is identical to the DAB Module with the exception of a power hybrid combiner at the output which combines both signals to provide two 25 Watt GSM signals on a common output. The Triple Duplexer Module (TDM) consists of three duplexers, which combine the transmit (TX) and receive (Rx) signals on a common antenna (ANT) port. A Splitter-Bias-Tee and Low Noise Amplifier (LNA) option is available to provide DC pass-thru and receive diversity for particular BTS equipment such as the Ericsson RBS 2102 configured with CDUA’s. The Power Supply Unit (PSU) consists of a AC to DC Converter which is capable of powering up to four DAB or DAC Modules. An optional battery back-up circuit is available that can tap into the existing BTS battery bank during the loss of AC power. All of the modules contain alarm and monitoring circuits and provide relay contact closures that can be tied into the BTS alarm circuit.
