The first iteration worked well enough that I decided to make this into a proper product and integrate everything onto a 4-layer board; The DFM (design for manufacturability) is now complete and the PCB + stencil has been submitted to the fab.

All designs uploaded to github.

I'm also doing a kickstarter to make this low cost VNA available to hobbyists:
