Questions
How big is the S Band Transceiver PCB?
It measures 127 × 101.6 mm and has 4 copper layers, 1.61 mm thick.
What parts does the S Band Transceiver use?
224 parts, built around the DCW-22-332+, SN74LVC1G125DCK, TSS-53LNB3+ and DAT-31A-PP+. 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 S Band Transceiver KiCad files?
From the tkeller12/openEPR repository on GitHub, at the commit this page was made from: the board is Hardware/S-Band Transceiver/S-Band Transceiver.kicad_pcb and its schematic Hardware/10MHz Reference/10MHz Reference.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the S Band Transceiver design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
