Overview
Switch breakout is an open-source printed circuit board by loxodes, from the loxodes/vna repository on GitHub. It is a 4-layer board of 22.8 × 21.8 mm with 102 parts on 9 nets, routed with 54 tracks and 4 vias.
It is built around the PE42521C-Z. Its parts include 5 capacitors, 4 ICs and 1 connector. It belongs with the radio and wireless and sensors and measurement boards of this library.
Main components

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 Switch breakout PCB?
It measures 22.8 × 21.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Switch breakout use?
102 parts, built around the PE42521C-Z. 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 Switch breakout KiCad files?
From the loxodes/vna repository on GitHub, at the commit this page was made from: the board is breakouts/switch_breakout/switch_breakout.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Switch breakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask loxodes before reusing the design.
