Hi Yeong,

Please look at the next Application Note.

https://www.nxp.com/docs/en/application-note/AN5136.pdf 

3.2. Kinetis KW01 configuration for packet reception at 315 MHz or 434 MHz and Table 1. Band-Specific MRB Components

The 1:1 (50/50) was found to provide the best performance for our FRDM, TWR and USB designs which is why it was used.

Regards,

Mario
