Should the Antenna (ANT) pin be left floating or tied to GND if not in use?

I'm creating a pcb with the nRF52833 and i'm not using radio. I plan on removing the inductors and capacitors connected to this pin and just leaving it floating. Is this correct practice?

Should all pins that are not in use be left floating as well?

Hi,

You can leave the ANT pin floating, but to be on the safer side, you can ground them via a 49.9Ohm resistor, and you can ground the VSS pin to the center pad.

In general, it's okay to leave any unused GPIO pins floating, but it's always safe and best to ground them.

Best Regards,
