My suggestion would be to draw this stage in ADS (advance design system) , check S22 of first stage over your frequency range, take impedance value at center of your frequency band, note it down..
Now draw the second stage and check S11 now, note center value this would be the input impedance of second stage, write it down.
Now through "Smith Chart Matching" utility of ADS, you can have your matching network, which actually transforms your output impedance of first stage to the input stage of the second stage..
But brother you need to first study about matching basics..
I hope someone has a better solution
