Page 61: Gtr 8000 Base Radio Theory Of Operation
GTR 8000 Base Radio Theory of Operation For an understanding of the GTR 8000 Base Radio components, review the modules that provide the base radio functionality, the modules that provide RF distribution functionality (RFDS), and the backplane that connects to other modules within the site.
Page 62: Transceiver Control Board
GTR 8000 Base Radio • Transceiver RF Board: Contains DC power conversion/regulation and performs receiver and exciter functions. • Transceiver Option Card: An optional board that attaches to the control board. Provides an internal 10 MHz frequency reference. For conventional base radio/receiver operation it also provides the analog interfaces and wildcard I/Os.
Page 63: Exciter
2.1.1.2.1 Exciter 2.1.1.2.1 Exciter The exciter on the XCVR RF board provides the transmitter functions for the base radio. The exciter circuitry generates a low-level, modulated RF signal that passes to the power amplifier. It supports various modulation types as well as bandwidths up to 25 kHz, through software programming. The exciter also provides a controlled output power level to the power amplifier.
Page 64: Transceiver Option Card Intercom Button
GTR 8000 Base Radio 2.1.1.3.2 Transceiver Option Card Intercom Button There is one intercom button on the front of the transceiver option card, accessible behind the fan module. Pressing the intercom button toggles the intercom function between the ON and OFF states.
Page 65: Power Amplifier Input/Output Connections
2.1.2.1 Power Amplifier Input/Output Connections The power amplifier (PA) is a forced convection-cooled RF power amplifier. It accepts a low-level modulated RF signal from the transceiver module, and amplifies it for transmission through the site transmit antenna. Also, to complete the Cartesian correction loop (linearization method), it provides a low level RF feedback signal to the transceiver module to achieve the required transmitter linearity.
Page 66: Function Of The Fan Module
GTR 8000 Base Radio • RF input/feedback (backplane connection). Figure 2-7 Power Amplifier (Backplane Connections) 2.1.3 Function of the Fan Module The fan module provides intermittent forced air cooling for the power amplifier and transceiver modules. The fans are controlled by a thermostat in the modules behind the fan module. The fan module houses two 119 mm axial fans which deliver a total of approximately 160 cubic feet per minute of airflow.
