Hi,

The BOOSTXL-CC1125 is for use at 868/815 MHz due to the matching network.

The CC1125 reference design for 433 MHz is CC1125EM_420_470 (SWRR101): https://www.ti.com/lit/zip/swrr101

You would need to modify both the BOM to that used in SWRR101 and also use an antenna designed for 433 MHz (as you mention).

Hi Zack

Just to make sure

i need to buy the BOOSTXL-CC1125 and do relevant RF matching for 433 include changing the antenna?

Hi Yair,

Yes that would be required for the BOOSTXL-CC1125 to operate at 433 MHz.

Alternatively, you could select a relevant CC1125 3rd party module (designed for operation at 433 MHz) from our list:
