Question

Hi,

What should the default component values be for the SRCW004 antenna matching network & DC blocking capacitor?

Thanks,

Jason

Answer 1

Hi Jason,

R1 as mentioned in the datasheet should start with a 0 ohm resistor. This may change to either a capacitor or an inductor depending on whether or not your center frequency shifts with the Weii is integrated into your device. The Pi matching components should initially start with a series 3.9nH inductor followed by one shunt 0.5pF capacitor. These will be adjusted to improve your return loss once the antenna center frequency is adjusted.
