Questions
How big is the Rf switch PCB?
It measures 23.1 × 34.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rf switch use?
21 parts, built around the ADG918BRMZ, AP7384-33Y and SN74LVC1G14DBV. 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 Rf switch KiCad files?
From the Naegolus/streaming repository on GitHub, at the commit this page was made from: the board is ecad/transmission-lines/rf-switch/rf-switch.kicad_pcb and its schematic ecad/transmission-lines/rf-switch/rf-switch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rf switch design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
