Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.

Load impedance (ohm)

Required number input.

Source impedance (ohm)

Required number input.

Compute the voltage reflection coefficient at the junction of a source and load impedance. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Reflection coefficient

The resulting reflection coefficient returned as a number.

• RF gain, noise, compression, intercept, mismatch, sensitivity, and link calculations require consistent impedance, bandwidth, frequency, reference plane, temperature, modulation, and cascade ordering. Datasheet values at different conditions cannot be combined without correction.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.

• PCB Impedance Mismatch Reflection

  Calculate signed voltage reflection coefficient at a PCB transmission-line load as (Zload−Z0)/(Zload+Z0) for real positive impedances.

• Battery Internal Impedance

  Estimate DC battery internal resistance from the voltage drop between two load-current operating points measured over a short interval.

• Common Mode Filter Attenuation

  Estimate common-mode series-filter insertion loss into a resistive load from measured complex common-mode impedance at the selected frequency; source impedance is assumed zero.
