About tosmithchart.com
tosmithchart.com is a browser-based RF engineering toolkit focused on quick Smith Chart analysis, reflection metrics, and practical calculator workflows.
Why this project exists
Many RF teams still exchange impedance trajectories in spreadsheets. This site keeps that workflow intact: you can copy-paste from Excel, visualize immediately, and read engineering metrics without installing desktop software.
What is included
- Excel-friendly Smith Chart plotting (multi-set input)
- Reflection coefficient (Re/Im, magnitude, phase)
- VSWR, Return Loss, Mismatch Loss, reflected/transmitted power
- Z <-> Gamma batch converter and VSWR calculator pages
- RF calculator suite: dB/dBm/W/Vrms, transmission line phase/length, reactance/resonance/Q, and cable power factor
Engineering note
Results are intended for fast analysis and review. Always verify final design decisions with calibrated measurement data and reference-plane aware simulation/measurement workflows.
