• INTRODUCTION

This Operator’s Manual covers the use, operation and installation of the BDA-1000 800 & 900 MHz Bi-Directional Amplifiers
(BDA’s). BDA’s are intended to extend radio frequency coverage into areas with coverage deficiency such as inside office
buildings, shopping malls, hospitals, tunnels etc. They are designed to be located independent of the Donor Transceiver Site and
are equipped with their own antenna systems - one to communicate with the Donor Transceiver Site and the other(s) to
communicate with radio equipment in the area with coverage deficiency.

For proper BDA System operation with no feedback problems, the RF isolation between the roof top antenna and the indoor
antenna(s) must exceed the net system gain by at least 12 dB. Note that the net system gain takes into account the BDA gain,
antenna gain, cable & connectors losses.

Power and Control Connections ------­RF Connections ____

BDA Controller : An enclosed unit with microcontroller, LED indicators, buttons, and two-line display.
Temp Sense & Cooling Fans : Controlled by the BDA Controller to ensure safe and reliable operation.
28V Power Supply : Providing all DC Power, with optional Gell-Cell Battery Backup.
Duplexers : Isolating Downlink and Uplink Frequencies, and coupling to antennas.
Reject Filters : Installed if required to eliminate feedback.
Boosters : High Gain (11 to 65 dB) Linear Amplifiers supplying up to 1 Watt of RF Power. The

basic gain is adjustable via the BDA Controller over a 33 to 65 dB range, and an
Automatic Gain Control (AGC) provides an additional 23 dB range.

PA Power Amplifiers : Optional Linear Power Amplifiers providing 15 dB of additional gain, and up to 20 Watts

of RF Power.
