Inquiry Regarding Antenna Options for STM32WB5MMG

[KWOOJ]

Hello,

I'm in the process of developing a device using the STM32WB5MMG, and I have a query regarding the wireless testing method for the final product.

I need to conduct tests using an antenna (external antenna) approved by the certification body rather than utilizing the built-in antenna on the MCU.

Could you please confirm if there is an option similar to STM32WB1MMC where external/internal antenna selection is available, or if there is a method to use an external antenna?

I have attached the antenna options section from the datasheet of STM32WB1MMC for reference.

 

 

Thank you.

Hello @KWOOJ 

As indicated on the part 3.4 of the DS13252, There is no option to use an external antenna:

I checked what you said. Thank you for answer.

I have one more question, Is there any way to remove the internal antenna?

[STTwo-32]

the internal antenna is integrated on the design. so, it is not possible to remove it.

Best regards.
