## Description

The dBCalculator software comprises five independent calculation tools:

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.

PLEASE NOTE: Calculations based on correlated vs uncorrelated levels yield very different results. If you see an unexpected result, please verify the uncorrelated/correlated setting of this app first!

The dBCalculator software is based on the application note
