Hello again,

I have another question regarding the RFX900 daughterboard.

  


Typically about 250 mW if you send a full-strength signal.  If you back 
off to about 100mW you will get better linearity.


I am trying to get a sense of the power transmitted by the RFX900 board 
in order to avoid breaching European communication regulations.


Ideally a figure for the equivalent isotropically radiated power (EIRP)
would be great.
  


That depends on your antenna and your settings for signal level.  If you 
want to transmit a weaker signal, send a smaller signal to the USRP.



Will the power output be different with and without the SAW filter?
  



Yes.  You will gain about 1-2 dB by bypassing the filter.
