Fxth 8700

Hi,

 

I'm using the chip Fxth8700 for a TPMS project.

 

I need help to design the matching network for the antenna (433MHz) , because I'm not expert on that field.

 

Q1) Why there is L1 between Vdd and the RF pin? Which value should it have?

Q2) Has the RF pin a source impedance of 50 ohms?

 

Thanks,

Riccardo
