Questions
How big is the Radar2 ExtFilter PCB?
It measures 79.1 × 47 mm and has 4 copper layers, 1.57 mm thick.
What parts does the Radar2 ExtFilter use?
74 parts, built around the DCW-11-722+, HMC385LP4, TRF37A73IDSGR and TS461CLT. 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 Radar2 ExtFilter KiCad files?
From the ear0/ECE445_Team18 repository on GitHub, at the commit this page was made from: the board is hardware/pcb/RadarV1.5/Radar2_ExtFilterUSE/Radar2_ExtFilter.kicad_pcb and its schematic hardware/pcb/IFBoard/IFBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Radar2 ExtFilter design in my own project?
Its repository states no licence, so its author keeps all rights: ask ear0 before reusing the design.
