SAFETY OPERATION INSTRUCTIONS
BEFORE USE
Review this manual and insure that all conditions are compatible with
the amplifier's specifications. Safe operation may be impaired if this
equipment is not used as intended.
GENERAL DESCRIPTION
This symbol is marked in the manual and denotes important safety
operation instructions. Please read carefully before continuing.
This equipment is suitable for a wide variety of scientific, industrial,
laboratory and communication applications where high levels of
electromagnetic Radio Frequency (RF) energy are required.
Therefore, the output of the amplifier must be terminated to an
appropriate load, such as a high power attenuator, dummy load, a
communication or radiation antenna. User must insure that radiated
energy do not violate
PROTECTIVE GROUND
This symbol is marked on the equipment and denotes protective ground
terminal.
This amplifier includes protective ground terminal. The equipment
shouldn't be used if this protection is impaired. The supplied power cord
must be used along with an uninterrupted external power source.
HAZARDOUS LINE AND RF VOLTAGES
This symbol is marked on the equipment where dangerous voltages are
present. Use extreme caution.
Both RF input and output connectors should be terminated prior to the
application of the external AC source. Otherwise, contact with the
RF output center pin can be dangerous. Place the amplifier in the
OFF position prior to connecting and disconnecting RF output load.
ELECTROSTATIC DISCHARGE (ESD)
This symbol is marked on the equipment where ESD sensitive devices
are present. Do not handle without the proper protection.
MAINTENANCE
Maintenance, repair and calibration must be performed by qualified
personnel only. Contact with the internal amplifier components maybe
dangerous even when the equipment is in the OFF position.
CAUTION This denotes a condition that may cause damage to the Amplifier if
procedure is not correctly performed. Do not proceed until the
indicated conditions are met.
FORCED AIR COOLING
Do not block the inlet and outlet of the internal cooling blowers.
Otherwise damage may result to the amplifier.

OVERVIEW
The BDA assembly enhances the coverage area of radio communications in buildings and RF
shielded environments.
The BDA has dual RF paths (Down-Link / Up-Link) to improve coverage in two distinct
frequency bands.
The unit features low noise figure and wide dynamic range. It is based on a dual duplexed
path configuration with sharp out of band attenuation allowing improved isolation between the
receiving and transmitting paths.
BDA-PS9-37/37-90-R provides up to 37 dBm composite power and has up to 85 db gain.
FCC NOTE
This is a Class B device. The product has been tested and found to comply with the Booster
requirements per FCC Part 90.
IC NOTE
The product has been tested and found to comply with the Industry Canada (IC) RF Exposure
Requirements, pursuant to IC RSS-131.
This device complies with Industry Canada license-exempt RSS standard(s). Operation is
subject to the following two conditions: (1) this device may not cause interference, and (2) this
device must accept any interference, including interference that may cause undesired
operation of
the device.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio
exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil
ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage
radioélectrique subi, même si le brouillage est susceptible d'en compromettre le
fonctionnement.
NOTE
The Manufacturer’s rated output power of this equipment is for single carrier operation. For
situations when multiple carrier signals are present, the rating would have to be reduced by
3.5 dB, especially where the output signal is re-radiated and can cause interference to
adjacent band users. This power reduction is to be by means of input power or gain reduction
and not by an attenuator at the output of the device.
RF EXPOSURE WARNING-FCC
In order to comply with the FCC RF exposure requirements, the BDA's antenna installation
must comply with the following:
The 8.5 dbi antenna must be installed so as to provide a minimum separation distance of
75.4cm (29.6 inches) between the antenna and persons within the area.

RF EXPOSURE WARNING- INDUSTRY CANADA
.
This system has been evaluated for RF Exposure per RSS-102 and is in compliance with the
limits specified by Health Canada Safety Code 6. The 8.5 dbi antenna must be installed so as
to provide a minimum separation distance of 87.3 cm (34.37 inches) between the antenna
and persons within the area.
L’exposition aux radiofréquences de ce système a été évaluée selon la norme RSS-102 et est
jugée conforme aux limites établies par le Code de sécurité 6 de Santé Canada. Le système
doit être installé à une distance minimale de 34.37 pouces (87.3 cm) séparant l’antenne
(8.5dbi) d’une personne présente en conformité avec les limites permises d’exposition du
grand public.
GENERAL DESCRIPTION
The downlink path of BDA receives RF signals from the base station, amplifies the signal and
transmits the signal, without changing the frequency, into a Distributed Antenna System at the
direction of the mobiles. The signal travels over a DAS medium that then dissipates the signal
to the Mobile subscribers. The uplink path receives RF signals at the Mobile side from the
DAS system, then amplifies it, and transmits the amplified signal (without changing the
frequency) to the base station.
This BDA supports Uplink and Downlink, 900 occupied distinct dedicated frequency bands.
The diplexer isolates the paths and route each signal to the proper amplifying channel.
An Automatic Level Control (ALC) allows for output power limiting. A variable step attenuator
gives 0 – 30 dB of attenuation in 2 dB steps. The use of these controls is covered in the
“OPERATION” section, later in this document.
