Section 1 General Description
1-1 Introduction
This manual contains information and procedures for installation, operation, and maintenance of
Powerwave’s model SPA9329-35N Two-Channel Power Booster Amplifier module. 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 SPA9329-35N is a linear, two-channel booster amplifier that operates in a bandwidth of 60
MHz from 1930 MHz to 1990 MHz providing 35 watts (45.5 dBm) per channel at the combiner
output port with a nominal gain of 21 dB total gain. The amplifier is modular in design, and ideally
suited for use in GSM base stations.
The amplifier, shown in figures 1-1 through 1-4, has a power input, two RF inputs, and one RF
output. Controls and indicators consist of a DC power switch for each channel, corresponding
LED power indicators, and alarm LED indicators (see section 3, table 3-1). Primary power for operating the amplifier is -48 VDC. Each amplifier module has a fan assembly contained in the rear
of the module, as shown in figures 1-2, to provide cooling. Air is drawn through the front of the
amplifier, over the internal heat sinks, and then exhausted by the fan.

Section 2 Installation
2-1 Introduction
This section contains unpacking, inspection, and installation instructions and recommendations
for the Powerwave model SPA9329-35N Two-Channel Power Booster Amplifier module. 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. 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. 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 (see paragraph 6.3). 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. WE CANNOT GUARANTEE

2-4 Installation Instructions
The SPA9329-35N booster amplifier module is designed for installation in enclosures that permit
access to the front of the module for connection of RF cables and the power connectors (refer to
paragraphs 2-5, and 2-6 for connector descriptions).
WARNING
Turn external primary DC power off before connecting any cables.
1.
Connect the power source to the booster amplifier power input connector (see figure 2-1, 31, and table 2-1). Do not apply power at this time.
2.
Connect the RF input cable(s) to the RF IN connector(s).
3.
Connect an RF cable from the RF OUT (Type-N) to the transmit filter input.
CAUTION
It is highly recommended that the output of the SPA9329-35N Booster Amplifier be fed
through an appropriate bandpass transmit filter prior to the transmit antenna input.
4.
Connect the antenna cable to the RF filter output connector.
5.
Refer to section 3 for initial turn-on and checkout procedures.
2-5 RF Connectors
The amplifier has two SMA female RF IN connectors and one RF OUT connector (refer to figure
3-1 for locations). The input power to the RF IN connectors should not exceed the level specified
in table 1-2. The RF OUT connector is Type-N female.
2-6 -48 VDC Power and Ground Connector
The -48 Vdc power and ground connections on the amplifier are made through a 3-pin female DSub connector (figure 2-1). Each pin and signal is listed and described in table 2-1.

Section 3 Operating Instructions
3-1 Introduction
This section contains operating instructions for the SPA9329-35N Two-Channel Power Booster
Amplifier module.
3-2 Initial Start-Up and Operating Procedures
Operating controls, indicators, and connectors located on the SPA9329-35N booster amplifier
module are listed in table 3-1 and corresponding locations for each are shown in figure 3-1. To
perform the initial start-up, proceed as follows:
1.
Verify that all power and RF input and output cables are properly connected as described in
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. Use
of any other cable will distort the output.
2.
Set the power ON–OFF switch to ON. The corresponding PWR and ALARM LED indicators
should illuminate.

Section 4 Principles of Operation
4-1 Introduction
This section contains functional descriptions for the SPA9329-35N Two-Channel Power Booster
Amplifier module.
4-2 RF Input Signal
The maximum input power should not exceed the limits specified in table 1-2.
4-3 RF Output Load
The load impedance should be as good as possible (VSWR ≤1.5:1) in the operating band for
good power transfer to the load.
4-4 Amplifier Functional Description
The SPA9329-35N power booster amplifier, shown in figure 4-1, operates in the 1930 MHz to
1990 MHz range. The operating band is determined by the operating frequency selection(s) of
the base station (refer to tables 1-2 and 1-3). The amplifier module consists of two single-carrier
amplifier pallets with necessary combining and filtering to produce up to 35 watts (45.5 dBm) of
output power with a typical gain of 21 dB. The amplifier employs class AB bias for maximum efficiency. The amplifier operates from a -48 Vdc power source.
The amplifier is compliant to requirements of FCC rules with respect to spurious emissions (see
tables 1-2 and 1-3). Most of the amplifier gain vs temperature variations are due to LDMOS transistor characteristics.

4-5 Amplifier Module Cooling
Each amplifier module is cooled using an enclosed rear-mounted fan circulating airflow across
the amplifier heat sinks. Air is pulled from the front of the module and exits at the rear. This provides sufficient cooling to maintain the amplifier within its safe operating temperature range.
4-6 Power Distribution
Primary DC power for the amplifier is provided by the host system. The amplifier generates all the
required voltages internally from the main source.
