Section 1 General Description

1-1 Introduction

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

Powerwave’s G3S-800-140-031 multicarrier RF 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 G3S-800-140-031 (see figure 1-1) is a linear, feed-forward power amplifier that operates in

the frequency band from 851 MHz to 869 MHz. The amplifier can simultaneously transmit multi-

ple frequencies, with better than -60 dBc third order intermodulation distortion (IMD). It is de-

signed for use in an amplifier system that is modular in design, and is ideally suited for use in

base stations. The plug-in Model G3S-800-140-031 amplifier modules can each provide 140

watts of power and function completely independently of each other. The amplifier modules are

designed for parallel operation to produce high peak power output and backup redundancy for

remote applications. All solid-state, the system is designed to provide trouble-free operation with

minimum maintenance. The system's modular construction and unique and highly effective

LED-based operational status and fault indicators help minimize downtime. The turn-on and turn-

off sequences of voltages are fully automatic, as is overload protection and recycling. Inadver-

tent operator damage from front panel manipulation is virtually impossible.

The amplifier module has a status connector that allows the host system to monitor the amplifier

module performance. The front panel of each amplifier module has unit level status/fault indica-

tors and an RF on/off/reset switch. Primary power for the amplifier is +27 Vdc. Cooling for each

plug-in amplifier module is provided by four fans, two mounted on the front and two on the rear of

the module. The fans draw outside air through the front of the module and exhaust hot air out

through the rear of the module.

1-3 Functional And Physical Specifications

Functional and physical specifications for the amplifier are listed in table 1-2.

1-4 Equipment Changes

Powerwave Technologies, Inc. reserves the right to make minor changes to the equipment, in-

cluding but not necessarily limited to component substitution and circuitry changes. Changes that
