Meh, this 1:9 #unun is not working properly or the connected 450 ohm load has a significant inductance that messes up the measurement 🤔

Also discovered that a #NanoVNA-H can malfunction when its battery is completely discharged, it only booted up again after disconnecting and reconnecting the battery... #hamradio #vectornetworkanalyser

Does anyone have open-source layouts for 2-port series and shunt component test PCBs using SMA connectors? Plus points if it's made for one of the JLCPCB stackups.
Something like the SV1AFN VNA test PCBs but as an open-source design that I can tweak a bit for different components. Also the SV1AFN design is shunt only.
