Saw this on eBay. Anyone have gerber files for something like this?

By the time you get the boards made and get the connectors, you have spent at least as much as Marcus is asking.
He has done the research and gotten the line section correct for the board material.

I ordered these to hack:

Oristo, I also ordered two if those, and a couple of 10 db attenuators. They look like a good test jig for experimenting with small components or transformers. I have one of the $9.00 eBay bridges, and a noise source. With a SDR as a detector I can do some Nano to Bridge comparisions, I hope.

Enhancing nanoVNA by an eBay 3GHz RF bridge is interesting.

Before getting nanoVNA, I considered using SDR and noise source with
eBay clone

Warren Allgyer seemingly reported comparable results

using 3GHz bridge with nanoVNA vs nanoVNA alone,
which resistive bridge was analyzed by alan victor

Wow - you have a lot of time to look up all of these posts!Are you going to put all this in the application notes section of the wiki?
