Just different spectral signature.
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.
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
don't like that.
Again, properly-engineered full-duplex RF systems use a duplexor for
precisely this reason.
