'A' Carrier:
The nonwire cellular company, that operates in radio frequencies from 824
to 849 Mhz.
AGC:
Automatic Gain Control - A feedback control circuit which maintains the
gain or output power level of an amplifier constant over a wide range of
input signal levels.
Airtime:
Time spent on a cellular phone, which is usually billed to the subscriber
on a per minute basis.
Alumina (Aluminum Oxide, Al2O3):
Alumina ceramic is used as the substrate material on which is deposited
thin conductive and resistive layers for thin film microwave integrated
circuits.
AM Noise:
The random and/or systematic variations in output power amplitude. Usually
expressed in terms of dBc in a specified video bandwidth at a specified
frequency removed from the carrier.
AM-PM Conversion:
