1GP77: dB Calculator

30 dBm + 30 dBm = 60 dBm? It is well known that it is not as easy as that.

This application note supplies a free of charge software tool that can be used to add or subtract an arbitrary number of powers. In addition, the software can be used to convert power and voltage units from the linear to the logarithmic scale (and vice versa), convert linear power and voltage ratios to decibels, and convert a VSWR to other reflection quantities.

dBm Calculator

This tools helps to add and subtract an arbitrary number of power levels expressed in units of dBm and watt.

Voltage Calculator

This tools helps to add and subtract correlated and uncorrelated voltage levels.

Unit Converter

This tool calculates for an entry using a unit such as dBm, dBW, mW, W, mV, V, dBV, dBµV and dBu the corresponding values for all other units, for individual impedance values.

dB Converter

This tool converts linear power and voltage ratios to dB and vice versa.

VSWR Converter

This tool converts reflection quantities such as Voltage Standing Wave Ratio VSWR, reflection coefficient, reflected power, return loss and mismatch loss.

The macOS version can be downloaded for free from the
