2-4.  INSTALLATION INSTRUCTIONS

  (Refer to figure 1-1)

The NTGS86AA amplifier module is designed for installation on a heatsink that permits access to
the module for connection of RF cables and the power, alarm, and control connector.

To install the amplifier proceed as follows:

1.  Install amplifier on heatsink with thermally conductive material inserted between amplifier

module and heatsink, and secure in place with four mounting screws.

 
2.  Connect the antenna cable to 

RF OUT

 SMA connector.

 
3.  Connect the transceiver output cable to 

RF IN

 SMA connector.

4.  Connect coupled RF output monitor cable to 

RF SAMPLE

 SMA connector.

 

WARNING

Turn off external primary DC power before
connecting cable to 18-pin Molex connector.

 

5.  Connect power, alarm, and control cable to 18-pin Molex connector.

6.  Check your work before applying DC voltage to the system.  Make certain all connections are

tight and correct.

 

7.  Measure primary DC input voltage.  DC input voltage should be +26 ±0.5 Vdc.  If the DC input

voltage is above or below the limits, call and consult Powerwave before you turn on your
amplifier system.

 

8.  Refer to section 3 for initial turn-on and checkout procedures.

2-5.  AMPLIFIER MODULE POWER, ALARM, AND CONTROL CONNECTOR

The power, alarm, and control connections on the amplifier are made through an 18-pin Molex
connector (figure 2-1) and are listed and described in table 2-1.

Figure 2-1.  Power, Alarm, and Control Connector (18-Pin Molex)
