Hi Ismail,

The actual reference design with values is here: www.ti.com/.../swrr116 . When using the CC2590 it is very important to follow the reference design closely, both for component values, but also on the layout.

Cheers,
Fredrik

Hi Ismail,

The values are based on RF measurements. More specifically we perform load- and source pull measurements and the use ADS to simulate appropriate matching values. Typically this is an iterative process.

Cheers,
Fredrik
