WebDec 10, 2024 · Power Budget = (-17 dBm) - (-30 dBm) = 13 dB It may seem odd that subtracting two numbers with dBm as the unit of measure results in a number with dB as the unit of measure. This is because a dBm is a logarithmic ratio of power relative to 1 mW. WebSecondly, the logarithmic scale converts multiplication to addition, which is convenient. A quantity in dB always represents a ratio. An absolute power level in "dB" is always given with respect to some reference value. For example, signal power in RF engineering is often given in "dBm", which are decibels with respect to 1 mW: Webwhere A is in dB. In this context, the logarithm is defined as being base 10.
