4. System Functional Description

The OPAF-1923-P07C01 is an AC powered, linear, feed-forward multicarrier power amplifier system that operates
in the 60 MHz frequency band from 1930 MHz to 1990 MHz with an instantaneous bandwidth of 25 MHz. It consists
of:

• One outdoor enclosure assembly.

• Up to six model G3S-1900-125 amplifiers (two per sector, each mounted in an MCR21929-1-2 two-way subrack).

• Six

• Four 930-00018-005, 148-amp rectifiers.

• One Low Voltage Disconnect system.

Duplexer Low Noise Amplifier modules

• Four 12 Vdc 105 AH Batteries .

• System Interface Module

Designed for outdoor use, the IP54 rated enclosure is a sturdy aluminum cabinet with front and rear locking
ventilating doors. Access to the RF, and alarm cabling is located at the lower sides and rear of the enclosure.
Access to the AC power cabling is located at the left side AC panel of the enclosure

The enclosure protects the Powerwave equipment from the outdoor elements as well as housing the System
Interface Module (SIM) and the electrical interface for the 148-amp rectifiers and G3S-1900-125 MCPAs
(Multicarrier Power Amplifiers).

The all solid-state G3S-1900-125 plug-in amplifier module MCPAs, , are designed to produce high-peak power
output. The modular construction and unique and highly effective Light Emitting Diode (LED)-based operation and
fault indicators always display the current operating status of the amplifiers. The turn-on and turn-off sequence of
voltages are fully automatic, as is overload protection and recycling. A nominal 52-Amps of current is required for
the G3S-1900-125 amplifier at rated output power.

Each of the three MCR21929-1-2 subracks, contain up to two MCPAs. The MCPA outputs are combined to provide
one composite output per subrack. Each subrack is equipped with an Automatic Power Control (APC) circuit and an
RF GAIN ADJUST potentiometer. The APC indicator and GAIN ADJUST potentiometer are located on the upper­right front of the subrack. Each subrack provides two RS-485 alarm interface ports, a preamp alarm interface port,
a Form-C alarm interface port and an RS-232 maintenance port, as well as, RF IN, RF OUT and a –50dB RF
sample port.

The 148-amp rectifiers and associated subracks require primary input power between 176 to 264 Vac. The rectifier
converts the AC input power to the +27 VDC for use by the system. The system design provides 12 minutes of
battery backup time with P/N 920-00337-003

Low Voltage Disconnect (LVD) monitors the output voltage of the battery system and disconnects the batteries from the circuit

batteries under a full operational load (3 hrs 30 mins. under a light load). A

044-05156 Rev C 6

when the battery voltage drops below 21 VDC. The LVD also provides the trickle charge path for the batteries during recovery
and normal operation.

The System Interface Module (SIM) monitors the performance and alarm state of the rectifiers, amplifier subracks,
and Duplexer Low Noise Amplifier (DLNA) modules.

4.1 Cabinet Overview

This section contains a functional description of the Powerwave OPAF Outdoor Multi-Carrier Power Amplifier
(MCPA) System. Refer to the system block diagrams below.

A complete OPAF system consists of a combined three-sector configuration that includes six G3S-1900-125
MCPA, 125-Watt amplifiers and three 4 KW (148-Amp), six Duplexer LNA (DLNA) assemblies, a System Interface
Module (SIM), four 220 VAC AC to +27 VDC rectifiers, a Low Voltage Disconnect (LVD) assembly, four backup
batteries and one outdoor enclosure.

The cabinet is equipped with four lifting bosses on the top panel. The lifting bosses are designed to carry six-times
the weight of the cabinet and its full contents, providing the weight is evenly distributed between the four lifting
bosses.

The cabinet provides easy cable and conduit access, to eliminate the need for external cable protective materials.
This eases the installation and maintenance of the cabinet. The cabinet is designed for ease of maintenance with
most modules and cables accessible either from the front of the cabinet, or side panel maintenance ports.

The cabinet provides 3 110 VAC GFCI courtesy outlets. 2 are incorporated in the front and rear light fixtures at the
top of the cabinet, the third is located inside the AC panel. 10 amps of service is available for these three outlets.

When connecting to the main service transformer, connect main ground and wire #61 to the Neutral bus.
When connecting to another AC panel, this becomes a sub-panel. Connect main ground to the Ground Bus and disconnect wire #61 at
the Neutral bus. Insulate the bare wires on #61 wire. Failure to disconnect wire #61 may cause a ground loop and a safety hazard,
resulting in injury or equipment damage.

Simplexed transmit RF input is provided by the BTS to the OPAF input bulkhead. The transmit signals are
combined (in the 16x16 configuration), amplified, then duplexed with the receive signals. The duplexed signals are
presented to a bulkhead connector for interface with the antenna port. The duplexer provides coupled samples of
the forward and reflected signals for BTS diagnostics.

Received signals from the duplexed antenna are separated from the transmit signals in the DLNA. The receive
signals are amplified by 45 dB through a low noise amplifier. The output signal is split into two paths, to allow for
future system expansion. Each sector has two DLNAs, one for the primary receive path and one for the diversity
receive path. The diversity DLNA only has transmit signals when the sector is expanded beyond eight carriers.

The SIM assembly monitors the MCPAs, LNAs, LVD, and rectifiers, and reports alarms via the I

interface.
