CC1311R3: CC1311R3 5x5 reference design of EU/US band

Hi Diego:

        Do you have the  CC1311R3 7x7 reference design of EU/US band? 7x7 it's also used in our products

Hi Zack:

        Thank you so much,you mean they are the same reference design.(CC1312R7  and CC1311R3 7x7)

Hi,

Yes - we recommend the same reference design for both devices in this case.

The CC1311R3 5x5 device has the design that Diego recommended above.

Regards,
Zack

Hi Zack:

        Got it,thank you again.

HI Zack, 

if customer want to make a 433/470~510MHz band on 5x5 package of CC1311. do you have recommendation how customer can start the design? 

for 7X7mm, I recommended them refer to CC1310‘'s reference.

Hi Albin,

CC1311R3 7x7 mm package:

For the CC1311R3 7x7 mm package we would not recommend the CC1310 design for 433 MHz.

Instead, the customer can use the LP-CC1312R7 (SWRC371): https://www.ti.com/lit/zip/swrc371 as a starting point, then use the 433 MHz BOM from the LP-CC1352P7-4 (SWRC373): https://www.ti.com/lit/zip/swrc373

As there will be no switch for the R3 devices, the customer can use the RF path up to C36 in the schematic below (plus the antenna section in the full design):

I will need to double-check the 5x5 mm recommendation and reply tomorrow.

Hi Zack：

          LP-CC1354P7-4？ I think it‘s cc1352P7-4,Is it correct?

Sorry, you are correct - the LP-CC1352P7-4!
