Meaning
Ampere (amp) is the unit of measure for electrical current.
Alternating current
Analog to digital
The ability to control an individual unit in a system of
many similar units.
Automatic Frequency Control
Automatic Gain Control
Amplitude Modulation
Two or more amplifiers in a series, the output of one
feeding the input of another.
Automatic phase control
Avalanche Photodiode. Avalanche refers to the gain
mechanism internal to the photodiode, where 1 photon
results in many electrons, as opposed to a PIN photodiode
where 1 photon results in 1 electron
Application Specific Integrated Circuit
A decrease in signal magnitude occurring in transmission
from one point to another or in passing through a loss
medium.
A device designed to reduce signal strength by an amount
specified in dB.
Addressable transmitter
Auxiliary
The total signal before it is modified for transmission or
otherwise manipulated.
A measure of signaling rate based on the number of
signaling events per unit of time.
Baseband digital reverse
The included angle between two rays (usually the half-
power points) on the radiation pattern, which includes the
maximum lobe, of an antenna.
