G3L-1929- Installation and Service Manual

Section 1. General Description

1-1 Introduction

This manual contains information and procedures for the installation and operation of Powerwave
Technologies, Inc.’s G3L-1929-120 Multi-Carrier Power Amplifier (MCPA). This manual is organ­ized into the following sections:

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 G3L-1929-120 Power Amplifier shown in figures 1-1 through 1-6, operates in the 60 MHz fre­quency band from 1930 MHz to 1990 MHz with channel spacing of 12.5 kHz. The amplifier provides
a typical gain of 60 dB to produce a typical output of 60 Watts (47.8 dBm). The G3L-1929-120 am­plifier generates approximately 2300 BTUs of heat at full power. The amplifiers are modular in
design, and ideally suited for use in GSM base stations.
