Amplifier selection help: DC amplification

I need help selecting an amplifier to amplify signal after an IQ mixer that is mixing signal down to DC. My requirements are as follows:

-Freq range: DC to 200 + MHz

-Single-sided input/outputs

-50 Ohm matched input and outputs (this could be accomplished with an evaluation board)

-Evaluation board option

-Non-inverted signal

-Gain: > 10


I had purchased the AD8330 - however the evaluation board is AC coupled, which completed distorted our DC signal. So I now need an alternative that will accomplish similar amplification (it does not need to to be variable gain), and I need to make sure is that the evaluation board associated with the amplifier is NOT AC coupled.
