That sounds very promising. There are a few wide band amps on Ebay which are in aluminium cases. I would probably get an open one, shorten the board and fabricate a box. I would be worried by the strain on the sma connector.
Maybe a future Tinysa could have a built-in switchable amp, which would then give a 60db controlled input range, with the built-in attenuator (woops, I am suggesting future possibke developments and I promised I would not do that any more).
