BFP640FESD has BVces 13V. Only 65 GHz.

13V?? 4V 46GHz ??


My followup doesn't seem to have made it.

You're right about the 46 GHz--I was confusing it with another part, thanks.

The 13V I was quoting is BV_CES, which is pretty good for a part that
fast. It shouldn't be too hard to arrange the circuit so that the base
drive is really low-Z at DC.
