Can I use CTE feature with single antenna by using nRF52811 + nRF52840 DK?

Hello, I'm a researcher.

I wanna use Bluetooth CTE(Constant Tone Extension) feature with 1-antenna TX + 1-antenna RX.

I have seen some articles that nRF52840 DK does not support Direction finding HW feature?

But, I just need to use 1:1 CTE sending and receiving.

Shortly, if I buy 2 sets(nRF52811 + nRF52840 DK), can one set send CTE packets and the other set receive these packets? and Can I get the I/Q samples?

p.s. Does nRF52833 DK support that? Which DK do you recommand?

Thanks.
