Questions
What parts does the HELIOS use?
3 parts, built around the ADF4351BCP and ADL5801. 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 HELIOS KiCad files?
From the JoshCrouch/HELIOS repository on GitHub, at the commit this page was made from: the board is Hardware/Hardware.kicad_pcb and its schematic Hardware/BPF_Bank.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HELIOS design in my own project?
Its repository states no licence, so its author keeps all rights: ask JoshCrouch before reusing the design.
