Introduction

Figure 1: GTR 8000 Base Radio

This manual provides information on the standalone GTR 8000 Base Radio and associated
applications. The term base radio or BR is used to denote the transceiver and associated modules. As
viewed in these instances, one base radio is a standalone configuration.
A GTR 8000 Base Radio consists of a transceiver module, power amplifier module, fan module, and
power supply. The transceiver module includes the functionality for the exciter, receiver, and station
control with an optional transceiver option card. The base radio software, configuration, and network
management, as well as inbound/outbound traffic handling, are performed through the transceiver
module. On-board serial and Ethernet service ports are on this module for local servicing through CSS.
The power amplifier module amplifies the low-level modulated RF signal from the transceiver module
and delivers the amplified signal on the path to the transmit antenna. The power supply module
supports the transceiver and power amplifier modules. Radio Frequency Distribution System (RFDS)
provides the interface between the transceivers and the site antennas and between the power amplifier
and the site antennas.
