Questions
How big is the Lna PCB?
It measures 35 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lna use?
22 parts, built around the PGA-103+. 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 Lna KiCad files?
From the Pancakemix31/Bandpass repository on GitHub, at the commit this page was made from: the board is lna-2025-03-06_181010/lna.kicad_pcb and its schematic lna-2025-03-06_181010/lna.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lna design in my own project?
Its repository states no licence, so its author keeps all rights: ask Pancakemix31 before reusing the design.
