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 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 modified to +24dBm upon customer request.
In addition the BDA has a trimmer that enables the reduction of the gain by 15 dB.
