You could use a SPF5043Z made by RFMD. It is a tiny MMIC in a SOT343
package. 
With a proper PCB layout of the power plane it should be very easy to
integrate it in the OsmoSDR PCB.

PS.: I really would like to see/do some tests on the influence of the
inductively of the header pins (including jumper) within the signal
path.
