Hello,
I recently assembled by SMA and BNC fixture board. You can find the gerbers and Kicad files at
The PCB is designed to work with the SMA or BNC versions of my VNA, but is likely going to be useful for NanoVNA too. It has the following features:
Built in female calibration standards for open, short, load, and thru.
A ZIF socket for easy testing of parts with leads where open, short, load, and thru calibrations may be applied.
A flat part of the board for testing SMA parts. The parts can be held down to the board with a toggle clamp or there are holes through the PCB to apply a vacuum to suck the part down to the board.
Four inputs for other types of test loads as needed.
If you want SMA and BNC boards, you should make separate boards for these, or otherwise the board is going to be too cramped.
