SPA9329-35 Installation & Service Manual

Section 1 General Description

1-1 Introduction

This manual contains information and procedures for installation, operation, and maintenance of

Powerwave’s model SPA9329-35 channel booster power amplifier. 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 sta-

tions.

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 corre-

sponding 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.

Section 2 Installation

2-1 Introduction

This section contains unpacking, inspection, and installation instructions and recommendations

for the Powerwave model SPA9329-35 booster power amplifier. Carefully read all material in

this section prior to equipment unpacking or installation. Also read and review the operating pro-

cedures 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 installa-

tion. 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 elec-

trical 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 con-

tainer(s) and remove the amplifier module(s). Retain all packing material that can be reassem-

bled 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 pack-

ing 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 pres-

ence of the delivery person. If the equipment is damaged, the carrier is your first area of re-

course. If the equipment is damaged and must be returned to the factory, write or phone for a re-

turn 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. WE CANNOT GUARANTEE THE FREIGHT CAR-

RIER'S PERFORMANCE

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 connec-

tors.

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 D-

Sub connector (figure 2-1) and are listed and described in table 2-1.

Section 3 Operating Instructions

3-1 Introduction

This section contains operating instructions for the SPA9329-35 power booster amplifier.

3-2 Initial Start-Up & Operating Procedures

Operating controls, indicators, and connectors located on the SPA9329-35 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, per section 2.

CAUTION

Before applying power, make sure that the input and output of the amplifier are prop-

erly terminated at 50 ohms. Do not operate the amplifier without a load attached. Re-

fer 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 co-

axial 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.

Section 4 Principles of Operation

4-1 Introduction

This section contains a functional description of the SPA9329-35 power booster amplifier.

4-2 RF Input Signal

The maximum input power should not exceed the limits specified in table 1-1.

4-3 RF Output Load

The load impedance should be as good as possible (1.5:1 or better) in the working band for good

power transfer to the load.

4-4 Amplifier Functional Description

The SPA9329-35 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 table 1-2). The amplifier module consists of a single carrier amplifier pal-

let 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 pas-

sive reference variations.
