General Description
1-1 Introduction
This manual contains information and procedures for installation and servicing of Powerwave’s G3H-85180 Amplifier. The manual is organized into two chapters as follows:
Chapter 1 General Description Chapter 4 Principles of Operation
Chapter 2 Installation Chapter 5 Maintenance
Chapter 3 Operating Instruction Appendix A Glossary of Terms
1-2 General Description
The G3H-851-80 Power Amplifier, shown in Figure 1-1through Figure 1-4, operates in the 18 MHz
frequency band from 851 MHz to 869 MHz with an instantaneous bandwidth of not more than 18 MHz.
The instantaneous bandwidth is the maximum frequency band in which any two or more signals can
occupy .The amplifier’s instantaneous bandwidth is set automatically and does not require any manual
setup.

Note
This Powerwave product is designed to operate within the normal operating (typical
operating) ranges or conditions specified in this document. Operation of this equipment
beyond the specified ranges may cause (1) spurious emissions that
violate regulatory requirements; (2) the equipment to be automatically removed from
service when maximum thresholds are exceeded; or (3) the equipment to not perform in
accordance with its specifications. It is the operator's responsibility to ensure this
equipment is properly installed and operated within Powerwave operating specifications to
obtain proper performance from the equipment and to comply with
regulatory requirements.
Industry Canada: The Manufacturer's rated output power of this
equipment is for single carrier operation. For situations when multiple carrier signals are
present, the rating would have to be reduced by 3.5 dB, especially where the output
signal is re-radiated and can cause interference to adjacent band users. This power
reduction is to be by means of input power or gain reduction and not by an attenuator at
the output of the device.
