Look at the NEC phemts... NE3509 is a pretty hot part. It will have roughly 10 times the Gm of the 2SK thing.

Hello Fran=E7ois,

I don't know what spec must be better (and the application), but you may try

descretes, RF discretes, etc. They have various MOSFETS and SiGe transistors.

Very impressive gain. It looks a very good candidate.

Thanks.

Thanks Wim. The parametric search is very useful. It is a pity such a tool is not provided by all manufacturers.
