I. INTRODUCTION

PURPOSE OF MANUAL:

The purpose of this manual is to outline the installation, describe the operation,

and assist in the maintenance and trouble-shooting for the Programmable Bi-directional
Booster Amplifier (PBBA), Model 50289-RBA-800MHz.

MANUAL OUTLINE:
Section II: Section II covers the general specifications of the PBBA. This

section outlines the general, mechanical and electrical specifications including the
module specifications (sub-assemblies).

Section III: Section III covers the instructions for installing the PBBA, site
requirements, and equipment initialization.

Section IV: Section IV cover operating procedures.
Section V: Section V is the recommended schedule of periodic maintenance

of the PBBA.
Section VI: Section VI covers the general “Theory of Operations” of the logic

and modules of a PBBA. This section is designed to aid in the understating of the
PBBA.

Section VII: Section VIII consists of diagrams, tables and procedures to assist
in the troubleshooting of an PBBA. This section is designed to guide a technician in
locating system fault(s) to the module. Included in the section is a lis t of recommended

test equipment.
Section VIII: Section IX consists of the schematic, assembly drawings, and

parts list of the PBBA and it’s sub assemblies/
Section IX: Section X consists of pertinent documents and equipment

manuals to supplement sections III, VI, VIII and IX.
Section X: Section XI lists the recommend spares for the PBBA.

GENERAL SYSTEM OVERVIEW:

(refer to drawing 50483-01-19)

In an off-the-air to radiating cable system, signals received from the air are
rebroadcast onto the cable. Signals received on the cable are rebroadcast over the air,
e.g., talk-in, talk-out.

In an off-the-air to radiating cable multiple Channel Booster application, the
PBBA is utilized to enhance the performance of the talk-out in long cable systems.

In general, the forward channel, talk-out signals are generated from lower power
sources, e.g., handheld transceivers.

PROGRAMMABLE BI -DIRECTIONAL BOOSTER AMPLIFIER OVERVIEW:

(refer to figure 1)

The Programmable Bi-directional Booster Amplifier (PBBA) is a software-driven
user-configurable unit for use in a multi-carrier low signal-level environment. It is
capable of eight (8) carriers and a composite power of –20dBm.

The forward channel covers 100 to 2000MHz and within this band a bandpass
filter defined window called the In-Band has a user settable gain. The factory
default setting is 20dB. The Out-of-Band gain 0dB. The reverse channel covers
100 to 2000MHz and utilizes passive components/elements to pass these
frequencies. This channel has fixed insertion loss due to the passive
components/elements.

The forward In-Band channel uses a broadband attenuator/amplifier module in
which the attenuation is digitally set via computer interface.

The forward In-Band channel has a high gain amplifier chain and a band pass
filter to boost a specific window of frequencies within the 100 to 2000MHz
frequency of operation.

Its small package and light-weight allows the user to conveniently install the unit.
Indicator lights allow the user to determine the status of the unit from a distance.
A user-friendly software enhances the unit’s performance and user interface.
