Overview
Txrx is an open-source printed circuit board by donzelot, from the donzelot/hn70ap repository on GitHub, published under the BSD-3-Clause licence. It is a 2-layer board of 25 × 25 mm with 33 parts on 22 nets, routed with 330 tracks and 126 vias.
It is built around the PGA-103+. Its parts include 7 capacitors, 7 resistors, 6 inductors, 4 connectors and 3 diodes.
Main components
1README
txrxswitch/README.mdThis folder contains a complete, stand-alone kicad project for a fast TX/RX switch that could be used with the main hn70ap circuit.
The design is experimental, in particular, I have no idea if isolation between the tx and rx branches is enough.
The project is released under the CERN OHL (schematic and board).

Questions
How big is the Txrx PCB?
It measures 25 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Txrx use?
33 parts, built around the PGA-103+. 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 Txrx KiCad files?
From the donzelot/hn70ap repository on GitHub, at the commit this page was made from: the board is txrxswitch/txrx.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Txrx design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
