README
README.mdOpen Hardware Vector Network Analyzer
I'm developing a proof of concept two port microwave vector network analyzer. The project is under developent. Ongoing documentation and logs are located on a hackaday.io project page.
Usage
This project is still under development, y'all probably don't want to try reproducing it yet. Two port measurements to 14 GHz work, a redesign for operation out to 36 GHz is in progress.
Hardware Design
See breakouts and hardware for various modules developed for the network analyzer.
Software Design
See the software directory for scraps of software written for testing VNA modules.

Questions
How big is the Vna control PCB?
It measures 73.7 × 72.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Vna control use?
175 parts, built around the OKR-T/3-W12-C, ADP7158A, TPS2041BD and DMG2305UX. 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 control KiCad files?
From the loxodes/vna repository on GitHub, at the commit this page was made from: the board is hardware/archive/vna_r0/vna_control/vna_control.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vna control design in my own project?
Its repository states no licence, so its author keeps all rights: ask loxodes before reusing the design.
