nRF54LM20B QFN52 — RF reference schematic, matching network BOM, and PCB layout request.

[Nishant Gaurav]

Hi Nordic team,

I am planning a new design using the nRF54LM20B in the QFN52 (QFAA) package and need your help with the following.

Background: I have reviewed the published reference layout for the CSP98 (PAAA) package (see attached image). I understand that these CSP98 values cannot be reused for the QFN52 package.

                                                                            

What I need:

1. QFN52 (QFAA)-specific RF reference schematic
2. Matching network BOM — component values, part numbers, footprints, and tolerances
3. Ground island design details — via count, via placement, and connection to die center pad
4. PCB stack-up and layer details
5. PCB layout files (Altium Designer preferred) if possible

Thanks and Regards

Nishant
