Hi Marcus,


Thanks for your answer. I do expect some of the Tx power to leak into my Rx chain, and my application can live with that. What I don’t understand, is why this power is much higher when transmitting packets than when transmitting a continuous tone.



Just different spectral signature.

Seriously, if you are TXing 70Mhz away from RX, and the antennae are more-or-less co-located, your RX is going to be overloaded.  RF amplifiers
  don't like that.

Again, properly-engineered full-duplex RF systems use a duplexor for precisely this reason.
