GENERAL DESCRIPTION
1-1. INTRODUCTION
This manual contains information and procedures for installation, operation, and maintenance of
Powerwave’s model NTGY81AA 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 NTGY81AA is a linear, multichannel power amplifier that operates in the 60 MHz frequency
band from 1930 MHz to 1990 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.
