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.

Maximum measurable return power (W)

Required number input.

Minimum detectable return power (W)

Required number input.

Convert maximum-to-minimum detectable reflected power ratio into reflectometer dynamic range in decibels. 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]

Power dynamic range (dB)

The resulting power dynamic range 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.

• Gain dB To Linear

  Convert an antenna power gain in decibels to a linear power ratio.

• Linear Gain To dB

  Convert a linear antenna power ratio to an equivalent gain in decibels.

• Dynamic Range dB

  Compute the dynamic range in decibels as the maximum signal level minus the noise floor, both in dBm.
