dB Calculator 2.3

dB Calculator comprises five independent calculation tools. It helps to add and subtract an arbitrary number of power levels expressed in units of dBm and watt. The tool allows you add and subtract correlated and uncorrelated voltage levels. It calculates for an entry the corresponding values for all other units. It converts reflection quantities such as Voltage Standing Wave Ratio VSWR, reflection coefficient, reflected power, return loss, and mismatch loss.
