no Yes that is true. However that input capacitance is close to what I'd
no use to bypass a 50mhz circuit. It's near RF dead short unless you
no try to absorb it into the feed network. Even then it's a very low Z.


Can one drive them with a grounded gate using a bipolar transistor at
the source?

Yes, but not with any significant power output and the gain would be
poor at high power. This is known as cascode configuration and is
used at low power (milliwatts) with good results.
