Dear Hossein, the B200 does NOT have a TX power control that would compensate that.
Are you perhaps either not changing A very much, or are you perhaps clipping? Driving your B200's TX amplifier into saturation would of course mean that you'd not see much of signal power reduction when reducing signal amplitude, until you cross the threshold where things become linear again.

I think USRP has something like this to control power.
