3-1 Introduction

This section contains operating instructions for the NTGS86AB Single-Carrier Cellular Power

Amplifier module.

3-2 Initial Start-Up & Operating Procedures

There are no operating controls or indicators on the NTGS86AB amplifier module. To perform the

initial start-up, proceed as follows:

1. Verify that all input and output cables are properly connected per section 2.

CAUTION

Before applying power, make sure that the input and output of the amplifier are prop-

erly terminated at 50 ohms. Do not operate the amplifier without a load attached. Re-

fer to table 1-1 for input power requirements. Excessive input power may damage the

amplifier.

NOTE

The output coaxial cable between the amplifier and the antenna must be 50 ohm co-

axial cable. Use of any other cable will distort the output.

2. Turn on supply that provides +26 Vdc to the amplifier system.

3. Turn on external exciter/transceiver and apply RF input signals.
