CC1352P: 20dBm trace with 0402 components

Maximilià Serra

Part Number: CC1352P

Hi all,

we are designing a PCB with the CC1352P chip and we will be using the Balun IC from Johanson for the sub-GHz and 2.4GHz traces.

For the 20dBm trace we want to have also sub-GHz (868 MHz), but we would like to use a bigger component size, 0402 instead of 0201.

Is there any reference design for the values of the components with such form factor?

Thanks for your support

Hi,

Please refer to the Reference Design CC1352PEM-XD7793-XD24-PA9093 under Design Files of the Following link.

Note that the lead time on 0402 caps can be long, please check that you are able to source the components you need before making the board.

Thanks to both!

Okay TER, we will check with the manufacturer before going ahead.

Hi,

the docs state 900-930 MHz.

What capacitor may need to be trimmed to extend the frequency window to include 868 MHz?

Thanks

Hi,

The same design can be used for 868MHz also.

Thanks,
