It's expressed as 'delay time'. Add up the relevant numbers. Beware that the most difficult part of switching a MOSFET is charging and discharging the gate.
nanosecond unit
(ns) 10^-9 seconds; one thousand millionth part of a second.
This is the unit in which the fundamental logical operations of modern digital circuits are typically measured. For example, a microprocessor with a clock frequency of 100 megahertz will have a 10 nanosecond clock period.

I think your numbers are backwards, John.
A longer time is a lower frequency, not a higher frequency.
One cycle of 400MHz lasts for only 2.5ns.
One cycle of 2000MHz lasts for 0.5ns.
The total of the rise time, turn off delay time and fall time must be less.
To answer the question the maximum frequency you can switch the MOSFET on and off at is 1/(the sum of all those delays) which is 1/590ns but I doubt you'd get a very good sinewave at that frequency due to the slew rate distortion.
A lot of info here. But I just want to know what the highest recomended operating frequency is for these mosfets.
Most transistors tell you in there data sheet what there frequency range is.
I don't know why they don't do that for the BUZ11 mosfet.
The data sheet mentions 4 different time periods
Should I take the highest of these and multiply it by 4 to get the most efficient time period?
240ns x 4 = 960ns rounded out to 1000ns per cycle.
Now how do I convert that to frequency?
Is it 1 Mhz?
