THEORY OF OPERATION
The BDA-1819-60 is a bi-directional amplifier. It is designed to exchange radio
communications in buildings, basements, tunnels and other RF shielded environments.
The BDA improves the sensitivity of base stations in indoor locations where there is a
significant amount of cable loss in RF distribution systems. BDA-1819-60 operates in
designated PCS bands.
It contains two amplifiers providing amplification of RF signals in Up-link and Down-link
frequency bands. They are connected to the external cables via frequency selective
duplexers in order to attenuate all signals that are not in the designated bands.
