AGC Automatic gain control is an RF output limiter that protects against
damage from oscillations and prevents excessive intermodulation
distortion.
Amplifier A class A amplifier. BDA cabinet contains four amplifiers, two for the
uplink/downlink path of A-band and two for the uplink/downlink path of B-
band.
Downlink Also called the forward path. In this path, the RF signal is transmitted
by the donor cell then received, amplified and re-radiated by distribution
system to the portable/mobile radio equipment
Interlock BDA controller function that allows the user to select (from Amplifier or
PA menu) which modules are to be disabled in the even that component
(Amplifier or PA) has a fault.
Line Amplifier Bi-directional amplifier that provides amplifications of RF signals to
recover signal loss contributed by system components such as radiating
cable, splitter and so on.
PA Power Amplifier. To increase power, some BDA cabinet contains two PA,
one for the uplink path and one for the downlink path.
Uplink Also called the reverse path. In this path, the RF signal is transmitted by
the portable/mobile radio equipment then received, amplified and re-
radiated by the distribution system to the donor cell.
