Rohde & Schwarz Application Note | R&S® dB Calculator 3 Overview 30 dBm + 30 dBm = 60 dBm? It is well known that it is not as easy as that. If we convert these logarithmic power levels to linear values, we get 1 W + 1 W = 2 W. This is 33 dBm and not 60 dBm. In addition, already, we face some trouble: we just want to do a simple calcula- tion, but we need to start thinking about the correct ...

• A letter following dB, such as dBm, indicates a specific reference value. See the table of commonly used reference values. • If given in dB, the gains (or losses) of a series of stages in a radio or communications system can be added together: • Losses are included as negative values of gain. i.e. A loss of 3 dB is written as a gain of -3 dB. Decibels – the History The need for a ...
