Where does the 19 dB come from? Is this for pulse transmission?

Off the top: the bandwidth range 1:400 is way too high, in fact the 8 pF has a 100 Ohm reactance only at 200 MHz. So you're probably looking at 100 MHz to 400 MHz, or a Q close to unity. For starters, try a series inductor of 10,000*8e-12 = 80 nH, which also gives a resonance in the right range. Or fix the resonance and fiddle the Q.

If you want a tighter performance, try a higher order Chebyshev LC ladder. But it's not worth the effort, I think.
