RF engineering tools

Calculate quickly without hiding the model. Every tool keeps units, reference planes, equations, assumptions, and edge cases close to the result.

Design principle
Editable engineering inputs. Immediate textual results. No decorative traces presented as measurements.
Start hereRF unit converter
The complete bench

From first conversion to measured network data.

Start with the smallest model that answers the question. Move into budgets, reflection, matching, and file-based analysis only when the required conditions are known.
