cc1101 in freq 403Mhz

Hi

we are using cc1101 for "mics" band which is defined to be 403Mhz.

I saw in the cc1101EM schematics the coupling network uses for 433Mhz and 915Mhz but my question is:

how can I calculate (or that you can calculate) the component values for 403Mhz coupling network?

thanks  in advanced,

Regards,
