Hello,
We intend to use the MKW01Z128CHN 434 MHz.
Could u tell me matching circuit part? What is the matching circuit?
Thank you for your time
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
