I have built a noise source using a series of amplifier modules, similar
to the MSA-0304.

It is essentually flat in frequency response up to several hundred MHz,
which I needed for my application. Granted, it took quite a few stages,
built in a couple of boxes to avoid any chance of instability due to the
high gain.

I did have to pay attention to the total integrated power, to keep the
output stage from distorting the noise, but for some sort of Rx bridge, it
would have more than enough drive.
