Questions
How big is the Vna se probe PCB?
It measures 18.8 × 11.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Vna se probe use?
5 parts, built around the P70-5000045R, RF2-143-T-17-50-G and SMTRAM4-9-7ET. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Vna se probe KiCad files?
From the antmicro/vna-se-probe repository on GitHub, at the commit this page was made from: the board is vna-se-probe.kicad_pcb and its schematic vna-se-probe.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vna se probe design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
