nrf52840 antenna with DC path to ground

[Ievgenii Meshcheriakov]

Hello,

I'm currently designing a board with nRF52840 and I'd like to use an antenna that is a DC short to ground. Do I need a DC blocking capacitor in such configuration or is it ok to connect this antenna to the chip without additional DC block?

Hello levgenii

You will not need a DC blocking capacitor on any chip in the nRF52 family.
