Hi everyone, The transmitter output path is RFpin → Choke → DC-Block → Matching Network (PI/T) → 50 Ω antenna. Because the datasheet doesn’t pin down the pin impedance, I probed it directly: Zin (RFpin) ≈ 6.6 – j108.5 Ω (|X|/R ≈ 16.4). I now want to confirm the loaded Q / -3 dB bandwidth of the...

Hey, I am currently trying to measure the AC-impedance of a coil (just one loop) I build with a simple copper cable. My approach was to measure the S-values for this specific part and wanted frequency with a VNA (Vector Network Analyzer) and calculate the impedance Z according to the measured...

This post is "picking the brains of smarter than me" more than anything. It's a simple question, but I can't seem to find a consistent answer to it. I have heard sooo many different suggestions and so many different "right ways" of doing this, that every way I try, gives different results...
