How RF Link Budget Calculator works
RF Link Budget Calculator calculates received power from the supplied parameters, with live validation, a readable formula note, and local browser processing.
Calculation model
Combines transmit power, antenna gains, and total path loss.
Recommended workflow
- Confirm every field uses the displayed unit.
- Adjust the example values and review the live result and input summary.
- Copy the result, then document assumptions and verify requirements before use.
Use cases
Use it for planning, comparison, documentation, and quick checks involving transmit power, tx antenna gain, rx antenna gain, total path loss.
Limits and verification
The calculation follows this stated model: Combines transmit power, antenna gains, and total path loss. Real projects may require additional coefficients, tolerances, taxes, codes, or professional review.
Frequently Asked Questions
Does RF Link Budget Calculator upload my values?
No. The calculation runs in the current browser tab and ToolHub does not receive or store the values you enter.
What does RF Link Budget Calculator calculate?
Received power from transmit power, tx antenna gain, rx antenna gain, total path loss.
Can I use the result in a real project?
The calculation follows this stated model: Combines transmit power, antenna gains, and total path loss. Real projects may require additional coefficients, tolerances, taxes, codes, or professional review.
Does it work on phones?
Yes. The input and result workspace adapts to mobile, tablet, and desktop screens.
Why can my result differ from another source?
Differences usually come from units, rounding, assumptions, local rules, or coefficients used by the other source.
