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.

Looking for resources on , I found out that every 2nd Saturday of the month there's the party (not a contest), next one coming up this week on Nov 12th.

Maybe it's the chance to finally work some contacts with this mode. Anybody planning to participate? I will most likely do.
