LAUNCHXL-CC1352P: Reference design for 433 MHz, 868 MHz and 915 MHz

Part Number: LAUNCHXL-CC1352P
Other Parts Discussed in Thread: CC1352P

Hi, TI team,

I am designing a product using CC1352P and wondering if the reference design is the same for different band of 433, 868 and 915 MHz?

I figure if the band is different, then the balun and filter circuits should be different accordingly, but what I've see from LAUCHXL-CC1352P schematic, it is using the same design and parts for all the bands.

Should I follow LAUCHXL-CC1352P schematic and use the same parts for all the bands?

Best Regards,

Evan

The match is equal on 868 MHz and 915 MHz but you need a different match for 433 MHz.

I assume that you want one RF path on 433 MHz, one on 868/ 915 MHz and then in addition have the opportunity to send with 20 dBm on 868/ 915 MHz?

Hi TER,

Thank you for your reply.

Do you have the reference design for the match of 433 MHz?

Actually I’m designing a module using this chip, so I’ll have two different part numbers for 433 MHz and 868/915 MHz, since the match is different.

Is that okay if I copy the LAUCHXL-CC1352P for the match for band 868/915 MHz? And use different match for 433 MHz. (If you have the reference, please share with me)

Best Regards,

EVAN

For 433 MHz you can use the following (0201 components):

And yes, you can copy a 869/ 915 MHz path from a LAUCHXL-CC1352P
