I think the BFW92 was the one in question,
looking at its charactaristics,
Ptot is 300mW
Po is around 8mW at 800Mhz
fT typicaly 1.6 GHz
SOT37 casing
For small signal applications, the above I mentioned should do the job, for higher power, the BFQ34T is recomended.
fT typicaly 3.7GHz
Vo ~ 750mV at 800MHz
again, SOT37 casing
