Page 4: 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). -
Page 5: General System Overview
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. -
Page 6: Programmable Bi-Directional Booster Amplifier Overview
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. - Page 7 PROGRAMMABLE BI-DIRECTIONAL BOOSTER AMPLIFIER PBBA MODEL 50289-RBA-800MHz P/N 50483-02-25 FIGURE 1...

Page 10: Installation
III. INSTALLATION The Programmable Bi-Directional Booster Amplifier is housed in a steel NEMA 4 enclosure. The enclosure has four mounting tabs on its rear surface (refer to drawing 50483-05-17).In selecting a mounting surface, the size and weight of the unit must be considered. The RF cables to the radiators (distribution system) are connected to female N-connectors on the bottom of the enclosure. -
Page 11: Operation Of Equipment
OPERATION OF EQUIPMENT The PBBA requires no operator settings or operation. It is designed for unattended operation. The following is all that is necessary for operation: INSTALL CONNECT TURN-ON WATCH LED... -
Page 12: Maintenance Schedule
MAINTENANCE SCHEDULE The Programmable Bi-directional Booster Amplifier is designed for unattended operation requiring minimal maintenance. General maintenance consists of equipment inspection an operational tests. Periodical equipment tune-up and alignment is recommended. Cable Inspection: The external and internal cables and connectors should be checked for indication of corrosion. -
Page 13: Theory Of Operation
THEORY OF OPERATION The PBBA is a broadband bi-directional amplifier. It has two channels, one is the Forward In-Band and the other is Forward Out-of-Band/Reverse. The Forward In-Band channel has a high gain amplifier chain and a band pass filter. This channel boosts the signals that come through the filter. -
