README
readme.mdVNA Testboard PCB
I really like this small PCB testboard for prototyping and experimenting with my Vector Network Analyzers. SDR-Kits used to sell it as a complimentary item for the DG8SAQ VNA. Unfortunately, mine showed some wear and SDR-Kits doesn't sell the PCB / Testkit anymore. So I clone it.
Layout
Design considerations
The PCB was designed in KiCad 7. You will most likely have to change / adopt the SMA connectors since I used a couple of non-standard ones which, I just had in stock.
I designed the traces as microstrip lines, matching 50 Ohm. This resulting trace width is 1.85mm using 1,0mm PCB thickness and an Epsilon r = 4.5 of the FR4 material. I get accurate results up to a few hundred Megahertz.
The pin sockets have a 2.54mm spacing.
I use Nylon M3 screws & nuts as feet.

Questions
How big is the Sdr kits testboard PCB?
It measures 38 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sdr kits testboard use?
16 parts. 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 Sdr kits testboard KiCad files?
From the dh1tw/vna-testboard repository on GitHub, at the commit this page was made from: the board is sdr-kits-testboard.kicad_pcb and its schematic sdr-kits-testboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sdr kits testboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask dh1tw before reusing the design.
