Questions
How big is the 4-way splitter PCB?
It measures 38.5 × 88 mm and has 4 copper layers, 1.6 mm thick.
What parts does the 4-way splitter use?
18 parts, built around the AD4PS-1+ and ESD7L5.0DT5G. 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 4-way splitter KiCad files?
From the m1geo/Antenna-Splitter repository on GitHub, at the commit this page was made from: the board is 4-way splitter/4-way splitter.kicad_pcb and its schematic 4-way splitter/4-way splitter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 4-way splitter design in my own project?
Its repository states no licence, so its author keeps all rights: ask m1geo before reusing the design.
