The manual is organized into six sections as follows: Section 1. General Description Section 2. Installation Section 3. Operating Instructions Section 4. Principles of Operation Section 5. Maintenance Section 6. Troubleshooting 1-2 General Description The SPA9329-35 is a linear booster amplifier that operates in a frequency range from 1930 MHz to 1990 MHz and provides 100 watts (50 dBm) of output power with a maximum gain of 23 dB. The amplifier is modular in design, and is ideally suited for use in GSM and EDGE base stations. The amplifier is shown in figures 1-1 through 1-5. Each amplifier module has a power input, one RF input, and an RF output. Controls and indicators consist of a DC power switch with corresponding LED power indicator and an amplifier over-temperature LED indicator (see section 3). Primary power input for the amplifier is +27 VDC. Cooling for the amplifier module is provided by one fan mounted on the rear of the amplifier module, shown in figure 1-1, which provides airflow over the two internal heat sinks. 1-3 Functional & Physical Specifications Functional and physical specifications for the amplifier are listed in table 1-2. 1-4 Ordering Information Table 1-1 lists the component numbers and descriptions to be used when ordering booster amplifiers or components.

Carefully read all material in this section prior to equipment unpacking or installation. Also read and review the operating procedures in section 3 prior to installing the equipment. It is important that the licensee perform these tasks correctly and in good faith. If applicable, carefully read the appropriate parts of the Federal Communications Commission (FCC) rules to determine how they apply to your installation. DON'T TAKE CHANCES WITH YOUR LICENSE. 2-2 Electrical Service Recommendations Powerwave Technologies recommends that proper AC line conditioning and surge suppression be provided on the primary AC input to the +27 Vdc power source. All electrical service should be installed in accordance with the National Electrical Code, any applicable state or local codes, and good engineering practice. Special consideration should be given to lightning protection of all systems in view of the vulnerability of most transmitter sites to lightning. Lightning arrestors are recommended in the service entrance. Straight, short ground runs are recommended. The electrical service must be well grounded. Each amplifier system should have its own circuit breaker, so a failure in one does not shut off the whole installation. Circuit breakers should be thermal type, capable of handling the maximum anticipated inrush current, in a load center with a master switch. 2-3 Unpacking & Inspection This equipment has been operated, tested and calibrated at the factory. Carefully open the container(s) and remove the amplifier module(s). Retain all packing material that can be reassembled in the event that the unit must be returned to the factory. CAUTION Exercise care in handling equipment during inspection to prevent damage caused by rough or careless handling. Visually inspect the amplifier module for damage that may have occurred during shipment. Check for evidence of water damage, bent or warped chassis, loose screws or nuts, or extraneous packing material in the connector. If the equipment is damaged, a claim should be filed with the carrier once the extent of any damage is assessed. We cannot stress too strongly the importance of IMMEDIATE careful inspection of the equipment and the subsequent IMMEDIATE filing of the necessary claims against the carrier if necessary. If possible, inspect the equipment in the presence of the delivery person. If the equipment is damaged, the carrier is your first area of recourse. If the equipment is damaged and must be returned to the factory, write or phone for a return authorization. Powerwave may not accept returns without a return authorization. Claims for loss or damage may not be withheld from any payment to Powerwave, nor may any payment due be withheld pending the outcome thereof.

All rights reserved 2-1 October 2002 SPA9329-35 Installation & Service Manual 2-4 Installation Instructions The SPA9329-35 booster amplifier module is designed for installation in an enclosure that permits access to the front of the module for connection of the RF cables and the power connectors. WARNING Turn external primary DC power off before connecting any cables. 1. Connect the +27 VDC power source to the booster power input connector (see figures 2-1, 3-1, and table 2-1). Do not apply power at this time. 2. Connect the RF input cable to the RF IN connector. 3. Connect the RF output cable to the RF OUT connector. 4. Refer to section 3 for initial turn-on and checkout procedures. 2-5 +27 VDC Power & Ground Connector The +27 Vdc power and ground connections on the amplifier are made through a 3-pin female DSub connector (figure 2-1) and are listed and described in table 2-1.

To perform the initial start-up, proceed as follows: 1. Verify that all power and RF input and output cables are properly connected, per section 2. CAUTION Before applying power, make sure that the input and output of the amplifier are properly terminated at 50 ohms. Do not operate the amplifier without a load attached. Refer to table 1-2 for input power requirements. Excessive input power may damage the amplifier. NOTE The output coaxial cable between the amplifier and the antenna must be 50-ohm coaxial cable. Use of any other cable will distort the output. 2. Turn on supply that provides +27 Vdc to the amplifier system. 3. Set the DC power ON–OFF switch to ON. The corresponding PWR and TMP LED indicators should illuminate. 4. Apply the RF input signal.

The operating band is determined by the operating frequency selection(s) of the base station (refer to table 1-2). The amplifier module consists of a single carrier amplifier pallet with the necessary combining and filtering to produce up to 100 watts (50 dBm) of output power with a maximum gain of 23 dB. The amplifier employs a class AB amplifier for maximum efficiency. The amplifier operates on +27 Vdc. The amplifier is compliant to the requirements of FCC Part 24 with respect to spurious emissions (see table 1-2). All gain variations, for example those due to temperature, are reduced to the passive reference variations.
