Yes, although with one synthesizer, it will be on the same frequency
for rx and tx

I do not have full characterization for you, but it will be dominated
by the antenna switch (U2), you can find the datasheet here:

Looks like ~30dB at 2.4GHz

It should be approximately the round-trip time for a control packet,
since you will not be tuning to a new frequency.  However, because you
can do full-duplex, I doubt you need to switch.
