The voltage noise is only 7 nV/rtHz @ 100 Hz (gain=2, I'll be using g=1), which is the best I've seen so far for a wideband amp. Not as good as the discrete transistor circuit, but it would use alot fewer parts.

I guess I'll have to build and measure, which I don't mind doing.

There is a guy selling some (5) PRS-10's on Ebay for $170. Says pulled from decommissioned systems, but sold for parts. No telling if they are any good... They are listed as being "used" and not "for parts"... which I think means Ebay says you can return them.

I am looking for a quick & simple way to create a frequency of 200 MHz from 10 MHz. Actually 100, 200, 300 or 400 MHz would all work, but 200 MHz would be my preference. The input will be around 0 to +10 dBm and the output needs to be about +13 dBm.
