AD9208 BW verses Sample Rate

 I am looking at using the AD9208 in a SDR application. If the datasheet states "direct sampling wide bandwidth analog signals of upto 5 GHz" but also specifies "-3dB BW of 9GHz", is the 5 GHz specified because the part is basically flat to 5GHz, and that most applications require that, while the part is still functional at the  "-3dB BW 9GHz" , the roll-off is generally undesirable?


Thank You!
