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.
