Definitions for dbm
This page provides all possible meanings and translations of the word dbm
The power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW).
dBm is an abbreviation for the power ratio in decibels of the measured power referenced to one milliwatt. It is used in radio, microwave and fiber optic networks as a convenient measure of absolute power because of its capability to express both very large and very small values in a short form. Compare dBW, which is referenced to one watt. Since it is referenced to the watt, it is an absolute unit, used when measuring absolute power. By comparison, the decibel is a dimensionless unit, used for quantifying the ratio between two values, such as signal-to-noise ratio. In audio and telephony, dBm is typically referenced relative to a 600 ohm impedance, while in radio frequency work dBm is typically referenced relative to a 50 ohm impedance.
