Can I use AD8367 without in/output 50-ohm matching networks or transformer?

I tested AD8367 evaluation board.

But this EVB has gain about 20 dB because in/output L-pad matching network has insertion loss of 11.5 dB.

I don't want to use L-pad matching network or transformer to get the gain 43 dB @ 70MHz.

I'd like to make simple circuit.

Actually, I used series capacitor 0.1 uF instead of 174ohm, 50 ohm series resistor and then I get about 43 dB gain.

 

I want to know that AD8367 work well without matching networks or transformer.
