Questions
How big is the Mu lna PCB?
It measures 100 × 77.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mu lna use?
55 parts, built around the ADA4523-1BRZ. 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 Mu lna KiCad files?
From the marcoreps/low_noise_amplifier repository on GitHub, at the commit this page was made from: the board is mu_lna.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mu lna design in my own project?
Its repository states no licence, so its author keeps all rights: ask marcoreps before reusing the design.
