Disclaimer

Last updated: 2026

RF Toolbox (rftoolbox.ca) provides free online RF and microwave engineering calculators, simulators, and reference articles. Please read this disclaimer before relying on any result from the site.

Use at your own risk

The calculators and all other content on this site are provided “as is”, for general reference and educational purposes only, without warranty of any kind — express or implied — including but not limited to accuracy, completeness, fitness for a particular purpose, or non-infringement. You use the tools and results entirely at your own risk.

Online calculators can be wrong

Like any software, these tools can contain bugs, and every calculator relies on simplified models, idealised assumptions, and approximations that do not capture every real-world effect. Results may be inaccurate, outdated, or simply incorrect for your specific situation. Rounding, unit handling, and edge cases can all introduce error.

Always double-check the numbers

Do not treat any result as authoritative. Before acting on a calculation, you should:

• Independently verify it — by hand, with the underlying equations, or against another trusted tool or reference.
• Confirm that the model and assumptions actually apply to your problem.
• Apply your own engineering judgement, and consult a qualified professional where the outcome matters (safety, compliance, cost, or performance).

Not professional advice

Nothing on this site constitutes professional engineering, design, safety, legal, or financial advice, and no engineer–client or advisory relationship is created by using it. You are responsible for validating any design and for compliance with all applicable standards, regulations, and safety requirements.

Limitation of liability

To the maximum extent permitted by law, the operator of RF Toolbox accepts no liability for any loss or damage — direct, indirect, incidental, consequential, or otherwise — arising from the use of, or reliance on, this site, its calculators, or their results.

External links

This site may link to third-party websites and resources. Those sites are not under our control, and we are not responsible for their content or accuracy.

Changes to this disclaimer

This disclaimer may be updated from time to time. Any changes will be posted on this page with a revised “last updated” date.
