Ask for AN5156 Layout recommendations's origin Altium PCB file?

[skycham]

Hi, I recently read the AN5165——Development of RF hardware using STM32WB microcontrollers，and the page25~page27 show the STM32WB55's reference design.

But I didn't find the file on the offical website.Could you please share the files named:

• MB1427A---UFQFPN48
• MB1422A---VFQFPN68
• MB1547B---UFBGA129
• MB1425A---WLCSP100

Thank you very much.

Hi. can you provide a final recommandation for capacitor values in the Impedance Matching Network near a PCB Antenna according to AN5129 ?

The value of NF, I think, needs to be determined based on the actual PCB test results.
