GUI for tuning coil connected to STWLC38

[BPolinske]

There are already a few posts which show there is an issue with getting the STSW-WPSTUDIO GUI downloaded. I replied to one, but I have yet to receive a response. I am looking to select capacitors to tune an RX coil connected to a STWLC38JR controller. It appears we need the GUI to accomplish this..?? Thanks in advance.

Dera BPolinske,

The GUI is not needed to select the capacitors in series with the coil.
You should target a resonant frequency F=1/(2*P*√LC) = 90kHz based on your coil inductance (L).

For reference, in our STWLC38 eval kit, the coil is 8µH and the total capacitors are 400nF (4*100nF).

Best regards,

Didier
