G3S-800-180-029 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-800-180-029 multicarrier cellular 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-800-180-029 (see figure 1-1) is a linear, feed-forward power amplifier that operates in the 25 MHz frequency band from 869 MHz to 894 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 AMPS/TDMA/CDMA/CDPD/W-CDMA base stations. The plug-in Model G3S-800-180-029 amplifier modules can each provide 180 watts of power nominally (210 W max.) and function completely independently of each other. The amplifier modules are designed for parallel operation to produce high peak power output and system redundancy for remote applications, when installed in multi-module amplifier subracks manufactured by Powerwave. 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. 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’s status. 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.

Section 2 Installation

2-1 Introduction

This section contains installation recommendations, unpacking, inspection, and installation instructions for the Multicarrier Cellular Amplifier. Carefully read all material in this section prior to equipment unpacking or installation. Also read and review the operating procedures 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 review the Federal Communications Commission (FCC) rules as they apply to your installation. DON'T TAKE CHANCES WITH YOUR LICENSE.

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 +27 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 electrical service must be well grounded.

Each amplifier system should have its own circuit breaker, so a failure in one does not shut off the whole installation. Circuit breakers should be capable of handling the anticipated inrush current, in a load center with a master switch. Powerwave recommends that a 100 amp circuit breaker be installed in the power distribution unit for each amplifier. DC wire smaller than 2 AWG 90°C copper DC should not be installed. Each amplifier should have its own DC cable pair. See table 2-1.

CAUTION

This table and the foregoing are provided as guidelines. Follow the appropriate NEC standards in your area and the cable manufacturer’s recommendation for proper cable selection.
