calc.engineer / RF & Antennas / Link Budget
Link Budget v1.0.0
Compute a full RF link budget from transmitter power, frequency, distance, and antenna gains. Calculates EIRP, free-space path loss (ITU-R P.525), received power at the receiver, and link margin relative to an optional receiver sensitivity threshold. Use this to determine whether a wireless link closes with adequate margin. Accepts output from noise_figure_cascade and feeds into snr_margin for full receive-chain analysis.
Fill in the inputs and Compute to see the structured result.
