Is this 14V Palomar the highest output FET amp out there?

I believe this is rated at 700W.

Does anyone know of anyone working on a higher powered FET amp?

Thanks.
 

most mosfets will tolerate 50 volts or more but the other components also have to tolerate that same voltage.


That's why they have to run a bucket of MOSFETS to make a kilowatt at 12 volts. That's like running a dozen sweep tubes at 600-700 volts to make similar power when all you have to do is ramp up the voltage and use a pair meant for the desired power output.
 
Sorry for any confusion. My fault for not writing up the subject line correctly.

I thought mobile voltage of 13.8 was nearer 14 than 12, however I hear where you're coming from.

OK, let's try this again.

From a '14 volt' rail do you think you'd see more out of say 16 X 2979's as against 16 of those 100W ERF FET's taking into consideration one would probably need a higher drive level for the latter.

I'm wondering if the FET's have the same or higher output at this voltage than the bi-polars once they're all combined?:confused:

    Incoming Region Produces X3 Solar Flare
    May 15, 2024 @ 14:55 UTC
    Another major solar flare, but this time from an active region just beginning to turn into view off the east limb. It is possible that the group responsible is old AR 3654 from the previous rotation. The latest flare, an X2.99 event just peaked at 14:38 UTC (May 15). Stay tuned
