BOOSTER OVERVIEW
The Booster provides an exceptional performances to extend the coverage area of radio
communications in buildings and RF shielded environments.
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 Downlink path receives the RF signals from base station, amplifies them and transmits them for
further distribution to the subscriber.
The Uplink path receives the RF signals from the subscribers, amplifies them and transmits them to
the base station.
Two duplexers separate the signals to the proper amplifying path and isolate between the the two
paths.
For each path there is a 40dB gain and a 30 dB step attenuator to set the Booster gain.
The power amplifiers in the Booster 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. This way the gain of the amplifier is
reduced, its output power is limited and the intermodulations products are kept below the desired
level.
The AGC amplifier has a Power LED lamp that illuminates when the output power has reached the
preset power limit.
