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.

Rf Input Dbm (dBm)

Required number input.

If Output Dbm (dBm)

Required number input.

Mixer conversion gain from desired IF output power and RF input power at the specified LO drive. 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]

Conversion Gain Db (dB)

The resulting conversion gain 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.

• Efficiency Percent

  Compute the percentage efficiency of a power conversion from output over input power.

• PA 1db Compression

  Input power at the measured one-decibel gain compression point from output power and small-signal gain.

• PA Backoff Efficiency

  Drain efficiency at a power-backoff operating point from RF output and DC input power.
