RF Switch for BLE antenna

[Saheb]

Hi,

As seen in datasheet nRF52840 has one antenna Pin. We can connect either PCB Antenna or Ceramic or External Antenna. Is there a way I can use any RF switch to toggle between PCB Antenna and External Antenna.

Thanks in advance,

Saheb

Hi Saheb, 

you can use a RF switch to be able to choose between two types of antennas. 

On our DK we have a "easier" fix, we have a U.FL connector with switch, so that when you connect an externa antenna you disconnect the on board pcb antenna.
