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
What parts does the Bias controller use?
203 parts, built around the RP2040, DAC5311IDCKRQ1, LM324DT and LDR6321. 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 Bias controller KiCad files?
From the loxodes/vna repository on GitHub, at the commit this page was made from: the board is breakouts/bias_controller/bias_controller/bias_controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bias controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask loxodes before reusing the design.
