CC1352P: CC1352P - Changes to the component values in the latest Launchpad design files

CC1352P: RF Performance difference when using 0201 and 0402 size packages

Part Number: CC1352P

Hello, 

I noticed a difference in the package size of components used on the Balun design for   latest launchpad design VS SWRA629A– Application Report for the Integrated Filter Balun for CC1352 design document.

Link : https://e2e.ti.com/support/wireless-connectivity/bluetooth/f/538/t/867996 

I would like to know if there's any RF performance differences,  and if that's the reason for the design update with 0201 components. 

 

Thanks

    Hi, 

    The main reason we have moved over from 0402 to 0201 package size for our RF front-end components is that it has been hard to source components in 0402 package size for the values we need. When we did the change from 0402 to 0201 we had to adjust the component values to get the same performance as we had on 0402 designs. This is why some of our reference designs has different component values.

    It is therefore very important that you use the same package size as being used in the reference design you follow.

    Hello Simon, 

    I currently have the 0402 components on my boards and there's an urgent customer requirement. I was wondering if there's no significant RF performance enhancement (which is crucial) , I could wait until the next batch production to change components to 0201.

    Kindly let me know.

    Thanks

    Hi Sanjay,

    As I wrote above:

    When we did the change from 0402 to 0201 we had to adjust the component values to get the same performance as we had on 0402 designs.

    I.e. you should get the same performance using 0402 and 0201 as long as you change component values accordingly.
