044-05079 Rev. A 1-1GENERAL DESCRIPTION1-1. INTRODUCTIONThis manual contains information and procedures for installation, operation, and maintenance ofPowerwave’s model NTGY81AA multichannel power amplifier (MCPA). The manual is organizedinto six sections as follows:Section 1. General DescriptionSection 2. InstallationSection 3. Operating InstructionsSection 4. Principles of OperationSection 5. MaintenanceSection 6: Troubleshooting1-2. GENERAL DESCRIPTIONThe NTGY81AA is a linear, multichannel power amplifier that operates in the 60 MHz frequencyband from 1930 MHz to 1990 MHz. It is designed to be mounted in an enclosure with EMIcontainment. Its flat base plate allows for mounting on a flat thermal-absorbing surface to provideadequate heat dissipation.Each amplifier module has a power, alarm, and control connector that allows the host system tomonitor the amplifier module performance. Primary power for the amplifier is +26 Vdc.1-3. FUNCTIONAL AND PHYSICAL SPECIFICATIONSFunctional and physical specifications for the amplifier are listed in table 1-1.Section1
