Product Description
Introduction
This manual contains information and procedures for installation, operation, and maintenance of the PAF-
0813-E0-001 Multi-Carrier Power Amplifier (MCPA) Indoor System. The manual is organized into chapters as
follows.
Scope of Manual
This manual is intended for use by service technicians familiar with similar types of equipment. It contains
service information required for the equipment described and is current as of the printing date. Changes which
occur after the printing date may be incorporated by a complete manual revision or alternatively as additions.
Product Description
The PAF-0813-E0-001 system, shown in the Figure 1-1 block diagram, is an 850 MHz, 4-way combined,
frame-mounted BTS solution. The PAF system contains three MCPA subracks, each capable of containing up
to four MCPAs, three filters, and one DC circuit breaker panel.
The MCPA subrack, shown in Figure 1-3, contains linear, feed-forward MCPAs that operate in the 869 - 894
MHz range. Each subrack is also equipped with automatic power control (APC), an ethernet connection, an
RS-485/RS-232 connection, a filter I/O port, and two cooling fans. The subrack is installed on sliding rails so
that it can be pulled forward to allow access to the rear of the subrack.
The MCPA, shown in Figure 1-4, is an 850 MHz module that produces a typical output of 160 watts (52.0
dBm) before system losses, with an instantaneous bandwidth of 25 MHz.
The filter assembly, shown in Figure 1-5, if used, supresses unwanted signals and non-linear components of
the signal from the amplifiers.
The circuit breaker panel, shown in Figure 1-8, consists of two +27 VDC input buses (A and B), and a system
circuit breaker panel. The panel receives +27 VDC from the BTS and then distributes circuit breaker protected
DC power to the individual subracks.

Installation
Introduction
This chapter contains unpacking, inspection, installation instructions, and recommendations for installing the
PAF-0813-E0-001 MCPA Indoor System.
Site Survey
Powerwave recommends that a site survey be performed prior to equipment ordering or installation.
Performing a detailed site survey reduces or eliminates installation and turn-up delays. Pay particular
attention to AC or DC power availability, cooling needs, floor space, and RF/DC cabling/breaker requirements.
See Chapter 5 for system dimensions and weights.
Space Requirements
The PAF system requires the following floor space for clearance (W x D x H): 28.5 inches (724 mm) x 78.2
inches (1986 mm) x 38.5 inches (978 mm). To properly service the system, an additional 48 inches (1220 mm)
is required in the front of the unit. To permit proper airflow, allow a minimum of 8.27 inches (210 mm) behind
the PAF.
Unpacking and Inspection
This equipment has been operated, tested and calibrated at the factory. Carefully open the containers and
remove the equipment. Retain all packing material that can be reassembled in the event that the unit must be
returned to the factory. Please perform the following steps:
❑Visually inspect equipment for damage that may have occurred during shipment. If possible, in
the presence of the delivery person.
❑Check for evidence of water damage, bent or warped chassis, loose screws or nuts, or extrane-
ous packing material in connectors.
If the equipment is damaged, file a claim with the carrier once the extent of any damage is assessed.
If the equipment must be returned to the factory, contact the factory for a Return Material Authorization (RMA)
as described in Chapter 4.
Electrical Service Recommendations
Proper AC line conditioning and surge suppression is necessary on the primary AC input to the +27 VDC
power source. Powerwave recommends that all electrical service be installed in accordance with the National
Electrical Code (NEC) and any applicable state or local codes.
Table 3-1 lists a sample of DC cable ratings.
Cooling Requirements PAF-0813-E0-001
3-2 044-05287 Rev A
Cooling Requirements
Each MCPA at full power generates the BTUs per hour listed in Table 3-3. A 1-ton air conditioner offsets
12,000 BTUs of heat. The MCPA operates within the temperature environment specified in Chapter 5.
Fan speed is dependent on MCPA operating temperature. The fans remain off until the MCPAs exceed +43°C
base plate temperature. Once enabled, the fan remains on until all MCPA base plate temperatures are below
+41°C.
Installation Instructions
Install the PAF frame, DC and RF connections, alarms, and MCPAs as described in the following paragraphs.
PAF
To install the PAF frame, perform the instructions in Table 3-4.

CAUTION: The PAF frame, as factory shipped, weighs approximately 250 lbs (113 kg) to 428
lbs (194 kg) depending on configuration (MCPAs not included).
NOTE Reuse shipping pallet washers to secure PAF to installation site floor.

Figure 3-1 Frame Installation
Seismic Brace (Optional)
The PAF system meets GR-63-CORE, Section 4.4.1, Zone 4 compliance. If additional bracing is required,
Powerwave offers an optional seismic brace kit for those circumstances. Please contact a Powerwave sales
representative for additional information and assistance.
DC Connections
Connect and verify DC power cables between the BTS power plant and the PAF system circuit breaker panel
and PAF return bus located at the top of the PAF as instructed in Table 3-5. Required power is +27 VBC, and
each power input is directly connected through the circuit breaker in the front of the panel to the power output
directly below it in the panel.i
Table 3-2 PAF Frame Installation Procedure
Step Action
1. Set PAF frame in planned location
2. Mark floor drill holes on floor where lag bolts will be installed. Move frame to side. Refer
to lag bolt manufacturer’s instructions for hole depth and diameter
3. Move frame back over drilled holes
4. Use a level to ensure frame is not leaning. Insert shims between frame base and floor to
level frame. Shims should wrap around lag bolts as shown in Figure 3-2
5. Secure frame in place with red eye lag bolts and appropriate washers
WARNING: Turn off external DC power before connecting DC power cables.
