BDA OVERVIEW:
The Bi-Directional Amplifier (BDA) assembly provides an exceptional repeater/booster
performances to extend the coverage area of radio communications in buildings and RF
shielded environments.
Features such as high linearity power amplifiers are contributing for the overall improved
system linearity performances. The unit is based on a duplexed path configuration, having
sharp out of band attenuation for improved isolation between the receiving and transmitting
paths.
BLOCK DIAGRAM DESCRIPTION:
The CBDA Downlink path receives the RF signals from base station amplifies them and
transmits them to the subscriber. The BDA Uplink path receives the RF signals from the
subscriber amplifies them and transmits them to the base station. Two duplexers frequency
separate the signals to the proper amplifying path and isolate the two signals.
The amplifiers in this BDA have an AGC option switch. When switched on, the AGC circuit
limits the amplifier output power. The AGC circuit senses the output power and introduces
more attenuation, when the output power exceeds the preset level of +27dBm*. This way the
gain of the amplifier is reduced, its output power is limited and the intermodulations products
are kept below the desired level.
In this manner the output power cannot exceed the +27 dBm* preset power and the IMD levels
are always kept below –13 dBm.
The AGC amplifier has a Power LED lamp that illuminates when the output power has reached
the preset power limit.
*Note: AGC preset level can be factory set to +24dBm upon customer request.
In addition the BDA has a trimmer that enables the reduction of the gain by 15 dB.

AGC & MGC FUNCTION
The BDA has AGC function. Their amplifier has a directional coupler and a detector at the
output of the high power amplifier to monitor the output power. When a high signal is received
the automatic level control detects the amplitude and sends a feedback signal to a voltage
variable attenuator which attenuates the signal level so that the output power of the amplifier
does not exceed the preset limit. The LED on the amplifier illuminates when the power out the
amplifier is within the set limit (both when the AGC is On and when the AGC is OFF).
The switch on the RF amplifier enables the AGC function. If the AGC is disabled then the
amplifier gives maximum gain.
MGC: The RF gain of the BDA can be reduced by about 15 dB using the continuos trimmer on
the amplifier. The RF gain is at maximum when the trimmer is at counter-clockwise direction.
To reduce the gain, turn the trimmer clockwise using a screwdriver. Turning it halfway would
reduce the gain by 7.5 dB.
The AGC and MGC functions for the uplink path are reached by opening a small cover located
on the DBA side adjacent to the Mobile antenna port. For the downlink path the window is
located on the side near the Base antenna port.

BDA INSTALLATION
Install the BDA Repeater in a shielded, ventilated and easy to reach area. Use low loss cables to
connect antennas to the BDA. Install the BDA close to the service area to improve output power and
noise figure. Mount the BDA with RF connecters pointing down. The RF connection is made via two
type “N” female connectors. The RF connector labeled “Base” must be connected to the antenna;
usually a Yagi; pointing to the base station. The RF connection labeled “Mobile” must be connected to
the antenna pointing into the area to be covered by the BDA.
BASE / DONOR ANTENNA INSTALLATION
Typically this is a directional antenna such as Yagi or Dish antenna of 10 to 15 dB gain. This antenna is
pointed to the base station to get maximum input power. This antenna should be in line of sight with the
base site. Raise this antenna higher if no line of sight is achieved. The required Base signals should be
the dominant signals; at least 6 dB higher power than other signals.
Choose the antenna site to get the maximum isolation from the remote (mobile serving) antenna.
REMOTE / SERVICE ANTENNA INSTALLATION
The remote antenna is an Omni antenna or a directional antenna according to the coverage
requirements.
For indoor applications covering a large building, the RF signals are split using power dividers and
distributed to many antennas each covering a floor or a small area.
ANTENNA ISOLATION
For proper operation the isolation between these two antennas must be at least 12 dB higher than the
BDA gain. Lower isolation would lead to high in-band ripple. Oscillations will build up when the isolation
is lower than BDA gain.
The isolation between the antennas is critical for high gain outdoor repeaters.
To measure the isolation; inject a known signal into one antenna and measure the power at the other
antenna. This should be done across the frequency range of both uplink and downlink bands.

INSTALLATION STEPS
1. Install all antennas and connect them to the BDA inputs.
2. Open the access windows at the sides of the BDA so that the variable attenuator is reached and the
LED is visible.
3. Turn the AGC On. This AGC limits the output power of the BDA. The AGC on the Downlink path
guarantees constant downlink power when and if the Donor power changes.
4. Set downlink gain to minimum; uplink gain to minimum ( by turning the gain control trimmer
clockwise).
5. Increase the downlink channel gain (by turning the gain control trimmer counterclockwise) till the
LED turns from off to on. This is the best gain setting giving highest usable power.
6. The LED on the downlink power amplifier will illuminate if adequate donor power has reached the
BDA. If the donor power is low the LED will not lit and the BDA usable power is not used efficiently.
7. Set the uplink gain to the same as the downlink gain.
8. Check that the uplink LED on the BDA monitor does not lit permanently. This LED would lit
permanently If the isolation between antennas is low (BDA oscillations) or the BDA is faulty.
9. If the uplink LED light permanently then:
•
Disconnect one of the cables from the BDA connectors and connect a load at the
connectors.
•
If the LED on this amplifier illuminates permanently then the BDA is faulty (oscillating) and
needs replacing.
•
If the LEDs stops illuminating then the isolation between the donor and remote antennas is
low. Either improve the isolation (e.g. increase separation) or reduce BDA gain.
•
To reduce gain, reconnect the antenna cables. Reduce the gain at both uplink and downlink
path until this LED stops illuminating. Reduce the gain further by 10 dB. This is the
maximum usable gain.

DIAGNOSTICS GUIDE
The BDA provides long term, carefree operation and requires no periodic maintenance.
This section covers possible problems related to the installation environment.
RF Faults and RF Power Amplifiers LED Indications
The LEDs on the power amplifier are set to turn on when the transmitted power has reached
or exceeded the specified composite power.
Normally the LED at the downlink power amplifier should be on indicating good forward power
transmission. The LED on the uplink power amplifier turns on only when a near by mobile is
transmitting.

RF EXPOSURE WARNING
In order to satisfy the FCC RF exposure requirements, you must ensure that the installation complies
with the following:
One antenna is connected via cable that has typical 1~10 dB attenuation (depends on the length of the
cable) to the BDA BASE port. This antenna is installed outdoor and has very sharp beam (Yagi type or
similar) pointed to the donor (BTS). This type of antenna has about 10 dBi gain. Typical specifications:
gain: 8 dBd (=10.1 dBi), VSWR: better than 1.5:1 , Impedance: 50 ohm. The outdoor antenna must be
installed to provide a minimum separation distance of 0.3 m (30 cm) from persons within the area.
The second antenna is connected via cable that has typical 1~10 dB attenuation (depends on the length
of the cable) to the CBDA MOBILE port. This type of antenna is omnidirecttional (isotropic), or wide
beam, with 0 to 2 dBi typical gain and is installed and distributes indoor (in buildings, tunnels,
basements, park lots, shopping centers etc.). Typical specifications: gain: 2 dBi, VSWR: better than 2:1 ,
Impedance: 50 ohm. The indoor antenna must be installed to provide a minimum separation distance of
0.2 m (20 cm) from persons within the area.
