Separate RX and TX antenna

[AlHe]

Is it possible to connected two separated antennas (single ended), one for RX and another for TX communications to the receiver and transmitter of the NRF51 or NRF52?

Thanks!

Hi,

Yes, this should be possible by using a RF switch/antenna diversity switch. You can then use PA/LNA control to tell when a TX or RX radio event is coming up, in order to switch between the TX/RX antennas.

Using two antennas for TX/RX is not a normal use-case, so we don’t have any reference design for this.
