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.

Max Gain Db (dB)

Required number input.

Min Gain Db (dB)

Required number input.

Peak-to-peak LNA gain ripple across a measured passband using the maximum and minimum observed gain. 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]

Flatness Db (dB)

The resulting flatness db 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.

• ADC Quantization Error Bound

  Calculate the ideal rounding quantizer's maximum absolute error as half an ADC LSB. Assumes a uniform quantizer and input within the conversion range; offset, gain, and noise errors are excluded.

• Antenna Rad Efficiency 2

  Infer antenna radiation efficiency in percent from measured gain and directivity via efficiencyPercent = 10^((gainDbi - directivityDbi) / 10) * 100.

• Current Shunt Amplifier Gain

  Voltage gain of a current-shunt amplifier from output swing and measured shunt input swing.
