Hi. I have to design a PCBA using the STM32WLE5 (STM32WLE5CBU6) at 169 MHz. I am looking for the passives components values to match and filter at 169 MHz. Thanks.

From AN Optimized RF board layout for STM32WL Series no recommandation are given for this frequency band.

Hello @Community member​ ,

Thank you for your interest !

You can also find information about RF design in the AN5457 - RF matching network design guide that may help you

Hope it helps

Hello,

I have been able to take a look at this AN, but nothing is provided at 169 MHz.

Hello,

The reference design will be published in the coming weeks. Waiting for it, I put in the attached zip file the schematic and the BOM associated to the 169MHz configuration.

Hope it helps,

Regards,

Damien.
