Suppose frf=1GHz with 200 MHz signal bandwidth (900 - 1100 MHz). Would I integrate then from 900-1100M or all the way from 1 to many GHz? How many?

A simple cross capacitively cross-coupled differential LNA gives me NF=1.65dB between 900-1100M and NF=2.61dB if I integrate from 1 Hz to 10GHz. Clearly Flicker noise kicks in a lot (corner at 1-10MHz).

PS: I do not have any bandlimitation such as SAW filter in front of the LNA (I do not have blockers, it's not a conventional RF receiver).
