Section GENERAL DESCRIPTION 1-1. INTRODUCTION This manual contains information and procedures for installation, operation, and maintenance of Powerwave’s model NTGY71AA multichannel power amplifier (MCPA). The manual is organized into six sections as follows: 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 NTGY71AA is a linear, multichannel power amplifier that operates in the 25 MHz frequency band from 869 MHz to 894 MHz. It is designed to be mounted in an enclosure with EMI containment. Its flat base plate allows for mounting on a flat thermal-absorbing surface to provide adequate heat dissipation. Each amplifier module has a power, alarm, and control connector that allows the host system to monitor the amplifier module performance. Primary power for the amplifier is +26 Vdc. 1-3. FUNCTIONAL AND PHYSICAL SPECIFICATIONS Functional and physical specifications for the amplifier are listed in table 1-1. 044-05080 Rev. A 1-1 Table 1-1.
