STM32WL LoRa matching network for CN470

[RayChoi]

Hi all,

 

We have a new project for LoRaWAN CN470 frequency band. We went thru the "RF Matching Network Design Guide (AN5457)" but couldn't find any info about STM32WL chip RF output pin impedance at CN470.  Could you provide the RFO_HP pin output impedance at CN470?

 

Best regards

Ray

Hello @RayChoi and welcome to the ST Community :smiling_face_with_smiling_eyes:.

Those results are obtained after tests that depends on different characteristics. To obtain the output impedance or how to test it, you have to contact one of our FAEs or Marketing teams. They should be able to help you.

Best Regards.
