G3S-800-140-031 Installation & Service Manual
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 multiple frequencies, with better than -60 dBc third order intermodulation distortion (IMD). It is designed 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 turnoff sequences of voltages are fully automatic, as is overload protection and recycling. Inadvertent 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 indicators 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, including but not necessarily limited to component substitution and circuitry changes. Changes that
impact this manual may subsequently be incorporated in a later revision of this manual.
