044-05178 Rev. A 2-1  October 2004 
Section 2  Installation 
2-1  Introduction 
This section contains installation recommendations, unpacking, inspection, and installation in-
structions for the SPA9323-30C single channel cellular amplifier. Carefully read all material in this 
section prior to equipment unpacking or installation. Also read and review the operating proce-
dures 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 Federal Communications Com-
mission (FCC) rules to determine how they apply to your installation.  
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 -48 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. 
The amplifier has an internal fuse, so a failure in one does not shut off the whole installation.   
2-3  Unpacking And Inspection 
This equipment has been operated, tested and calibrated at the factory. Only in the event of se-
vere shocks or other mistreatment should any substantial readjustment be required. 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, or loose screws or nuts. Inspect the front 
panel for bent connector pins. If the equipment is damaged, a claim should be filed with the car-
rier 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 (see section 6). Powerwave may not accept returns without a return authoriza-
tion.

4-4.2   Main Amplifier 
The main amplifier is a single-stage Class AB amplifier with approximately 13 dB gain and a 
P1dB of +50 dBm. The amplifier’s output is protected from output mismatches. The amplifier is 
designed to meet spectral mask requirements for GSM and EDGE signals when operated up to 
+45.2 dBm. The amplifier is mounted directly on a heat sink.  
4-4.3   Power Distribution 
The amplifier module operates on a –48 VDC nominal power supply consuming 2.9 amps (typi-
cally) current at full power. A DC/DC converter supplies internal circuitry with +26 VDC and +5 
VDC. 
4-4.4   Multifunction Board 
The multifunction board enables communication between the amplifier and the base-transceiver 
station in which it is installed, and stores information about the amplifier. It includes gain control 
and two gain stages providing a 7 dB gain. The multifunction board also monitors several ampli-
fier performance parameters and reports output power so that the BTS can maintain the output 
power within specified limits. When these parameters are beyond acceptable levels, the amplifier 
alarms. The multifunction board is mounted directly on a heat sink, which is temperature moni-
tored by a thermal sensor. 
The alarms are: 
Temperature Alarm - If the internal temperature reaches 90°C, the PA shuts down and com-
municates an alarm through the digital interface. 
DC/DC Alarm - If the output voltage of the converter falls below 23.5V, the PA shuts down 
and communicates an alarm through the digital interface. 
Over-current Alarm - If the output current of the DC/DC converter goes above a nominal 
threshold (7.5 A), the PA shuts down and communicates an alarm through the digital 
interface. 
Communication Alarm - If the serial interface detects an error in transmission (parity, over-
run, framing), an alarm is sent for one burst only during the very next burst. The PA 
operation is not affected.
