XoverPi calculator guides

RF & Electronics calculators that make decisions clearer.

Work through radio-frequency power, impedance, and signal calculations with XoverPi RF and electronics calculators.

RF power and decibels

dBm represents power referenced to one milliwatt. A power ratio in decibels is logarithmic, so do not treat dBm changes as linear watt changes.

dBm calculatorWork with RF power levels.dBm to wattsConvert logarithmic power and watts.VSWR calculatorEstimate voltage standing wave ratio.

Circuits and frequency

Resistor networks and frequency relationships assume specific idealized models. Real hardware also has tolerances and parasitic effects.

Ohm’s lawFind electrical quantities.Voltage dividerEstimate unloaded divider voltage.Series resistanceCombine series resistance.Frequency calculatorExplore frequency and period.Capacitor energyEstimate stored energy.
