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 im proved isolation between the receiving and transmitting paths. FORAM-AWSF-5/44-65-R3U15 provides up to 44 dBm on the downlink and 5 dBm on the uplink. The composite power has up to 65 db gain.

FCC NOTE

The product has been tested and found to comply with the Booster requirements per FCC Part 20 and 27.

IC NOTE

The product has been tested and found to comply with the Industry Canada (IC) RF Exposure Requirements, pursuant to IC RSS-131.

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.

ANTENA INSTALLATION NOTE

Operation in the 1710-1755 MHz band are limited to a maximum antenna height of 10 meters (~33 feet) above ground.

RF EXPOSURE WARNING-FCC

In order to comply with the FCC RF exposure requirements, the antenna installation must comply with the following: For UL signal, with 10 dBi gain antenna: The antenna must be installed so as to provide a minimum separation distance of at least 20 cm (~7.9 inches) between the antenna
connected to the RF booster and the human user’s body within the area. (VSWR ≤ 2:1, Zo=
50 ohms and a cable attenuation less then 1dB). For DL signal, with 10 dBi gain antenna: The antenna must be installed so as to provide a minimum separation distance of at least 184.42 cm (~72.6 inches) between the antenna
connected to the RF booster and the human user’s body within the area. (VSWR ≤ 2:1, Zo=
50 ohms and a cable attenuation less then 1dB).

RF EXPOSURE WARNING- INDUSTRY CANADA

In order to comply with the IC RF exposure requirements, the antenna installation must comply with the following: For UL signal, with 10 dBi gain antenna: The antenna must be installed so as to provide a minimum separation distance of at least 20 cm (~7.9 inches) between the antenna
connected to the RF booster and the human user’s body within the area. (VSWR ≤ 2:1, Zo=
50 ohms and a cable attenuation less then 1dB). For DL signal, with 10 dBi gain antenna: The antenna must be installed so as to provide a minimum separation distance of at least 263 cm (~103.5inches) between the antenna
connected to the RF booster and the human user’s body within the area. (VSWR ≤ 2:1, Zo=
50 ohms and a cable attenuation less then 1dB).

BLOCK DIAGRAM DESCRIPTION
following discussion. 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, AWS 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
