1.0 SAFETY CONSIDERATIONS
1.1 Electric Shock Hazard
To avoid electric shock, switch the BDA “OFF” prior to performing any repairs. All repairs beyond
modular replacement must be performed by Andrew Trained Technicians.
1.2 Hot Surface Hazard
RF power into the BDA will be limited by the use of high power attenuators. These attenuators
will be located at the transmitter source. Caution should be taken when working near high
power attenuators due to the risk of being burned by its hot surface.
Due to the amount of heat dissipated by the BDA heat fins, caution should be taken when
working near heat fins due to the risk of being burned by its hot surface.
1.3 Optical Laser Hazard
To avoid injury to the eyes, do not look directly into fiber optic transceiver transmit port (Tx).

2.0 EQUIPMENT OVERVIEW / DESCRIPTION
MBTA System Wide Radio Tunnel Antenna Distribution System provides extended radio
coverage within MBTA rail transit tunnels. The new tunnel antenna system is a two-way
communication system consisting of 400 MHz base transceiver stations, 800 MHz base
transceiver stations, antennas, radiating cable, fiber optic cable and BDAs. Both the 400
MHz and 800 MHz systems operate independently. The 400 MHz system operate as a
conventional analog voice communication system and the 800 MHz system operate as a
digital trunked radio system for voice and data communications. Radio signals routed
from the base transceiver stations to the BDAs are performed via fiber optic cable. Once
the optical signal is received by the BDA, it is converted back into an electrical (RF)
signal, amplified and transmitted throughout the tunnel antenna distribution system. For
RF signals transmitted within the tunnel, they are received by the BDA, amplified,
converted into a optical signal and sent via fiber cable to the base transceiver stations.
Each BDA is designed for a 19” rack mount cabinet and is equipped with interchangeable
modules. These modules are field replaceable by removing them from the front chassis of
the BDA. The modules consist of a downlink amplifier, uplink amplifier, high isolation
duplexer, low isolation duplexer (400 MHz RF fed BDA only), fiber optic transceiver
(fiber fed BDA only) and a AC to DC power supply. and alarm module (Optional
Equipment). All BDA controls are performed via a RS232 connector located on the front
panel of each amplifier module.
Each BDA has 30 dB of gain adjustment for both the uplink and downlink RF path. This
adjustment is varied electronically thru the amplifier modules’ front panel RS232
connector. Additionally, each of the amplifier modules are equipped with an Automatic
Level Control (ALC) circuit which can limit the maximum power level produced by the
BDA.
OPTIONAL EQUIPMENT (Not Used By MBTA)
An alarm module is available as an option to serve as a central communication agent to
monitor the status of each module and send a summary alarm to remote locations via the
fiber optic transceiver module.

5.0 MODULES
5.1 400 MHz EO Cell Amplifier Module (AE04A-D1264-001)
5.1.1 Description
This 2Watt, 483 - 487 MHz, class A Power Amplifier Module provides a nominal
52 dB of gain. It has 30 dB of gain adjustment range, which can be varied
electronically thru the front panel RS232 connector. Additionally, the module has
an internal Automatic Level Control (ALC) circuit, which can be set to limit the
maximum power level produced by the BDA. This module has an on board RISC
processor that provides optional alarming/status monitoring and communications
capabilities. The same module design is used for both the Downlink and Uplink
amplifier.
The amplifier modules contain high reliable RF parts to provide a long trouble-
free operating life. In the unlikely event of failure, the entire amplifier module
should be replaced.
