These are notes related to RF, Power, and Antenna studies while I'm studying for an Amateur Extra class license. They're in markdown for clarity and pics and math symbols are supported. Eventually I'll add jupyter notebooks related to NanoVNA use and antennas I build which use MathJax which has better math symbol support.
Please reach out to me if my notes could be improved or are incorrect in any way.
Mostly taken from the fantastic Rohde & Schwarz youtube channel.

The notes make the most sense if they're read (or viewed on youtube links in the notes) in this order:
- S Params
- VSWR
- Resistance/Reactance/Impedance (for a deeper dive or leave for later)
- Smith Charts
The .md files are "Mostly Working" math/LaTeX to express the formulas, created in VSCode with MarkdownMath and LaTex. Unfortunately they don't fully express LaTeX/MathJax symbols in the way that MathJax does. Github doesn't express these at all, so raw output like
