The Dual Amplifier-Combiner Module (DAC) is identical to the DAB Module with the exception of a passive hybrid combiner at the output which combines both signals to provide two 30-35 Watt GSM signals on a common output. RBS-2106 & RBS-2206 GSM Base Transceiver Station: The Base Transceiver Station (BTS) is a GSM Base Station which serves one cell and is controlled by the Base Station Controller (BSC). The RBS-2106 and RBS 2206 designate the outdoor and indoor versions of the BTS respectively. The BTS contains the radio transceivers and all the digital signal processing equipment. The BTS contains six double Transceiver Radio Unit’s (dTRU’s) for a total of twelve transceivers per BTS. The dTRU consists of two synthesized transmitters (TRX) operating in the frequency band of 1930 to 1990 MHz. There are 299 channels available with a channel spacing of 200 KHz. The transmitter is a constant envelope using 0.3 GMSK modulation, which is MSK filtered with a Gaussian filter, having a BT product of 0.3. The transmitter is capable of operating in a Time Division Multiple Access (TDMA) system. For each channel there are 8 time slots available, each containing digital speech or data. Operation Description: The DAC-1819 and DAB-1819 Dual Amplifier Booster/ Combiner in conjunction with the RBS 2106/2206 BTS are designed to supply a nominal output power level of 47.5 dBm when used in the uncombined mode and 44.5 dBm when used in the combined mode at the antenna connector. A system block diagram is shown on diagram #1 and #2.

The input to the Dual Amplifier Booster/ Combiner is the Transceiver Radio Unit (TRU) whose output can be set at 16 power levels in 2dB increments. As shown in diagram #1 and #2, setting the output level of the TRU to 41 dBm will result in a power level at the output of the Dual Amplifier Booster/ Combiner of 48.5 dBm in the uncombined mode and 45.5 dBm in the combined mode. The Dual Amplifier Booster/ Combiner is followed by a CDU-G module which contains both a low-pass filter and duplex filter. The low-pass filter secures the required reverse isolation and provides spurious and harmonic suppression of the output signal. The duplex filter allows a single antenna to be used for both transmitting and receiving. Due to the insertion loss of the CDU-G, the maximum output power at the antenna connector of the radio base station is 47.5 dBm in the uncombined mode and 44.5 dBm in the combined mode. Operation and Installation Instructions: The following instructions should be followed when installing the unit in service: • Apply a 26-28VDC 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 +41dBm to each RF input port of the Dual Amplifier-Booster/Combiner Module. • The Dual Amplifier-Booster/Combiner Module will provide approximately 7.5dB or less of RF Gain. • Check the RF output to insure the proper output power is present. {Approximately 65-70 Watts in the uncombined mode (DAB) or 30-35 Watts in the combined mode (DAC)}. • 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. z Page 3 Setting the RF Output Power on the DAB & DAC Booster Amplifier The RF output power is not adjustable on the DAB & DAC Booster Amplifier. 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. Channel Center Frequency (MHz) 1930.2-1989.8 Maximum RF 0utput (Watt)* 70 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 be fixed on an outdoor structure and that it must have a minimum separation distance of 2 meters between it and any person." z Page 4
