ad9680 and adrf6518 Integration

Hello everyone

I am thinking to create recevier IF section with ADL5380 adrf6518 and ad9680. There are low pass filters between the components.

Is this block diagram applicable for recevier architecture ?

Should I connect them directly or use rf transformer for impedance matching (ceramic filters matched to 50 ohm) ?

  What will be the recevier sensitivity at ADC Input? (from receiver antenna port to RF IN port of the ADL5380, cascaded gain is 40 dB and cascaded noise figure: 3 dB )



Thanks in advance
