cw vs pulsed power

Could someone explain to me if there is a rule of thumb to determine the peak pulsed power of an (linear class a/b) RF amplifier if the peak cw power is known. For instance, if the amp is rated 300W (max power) in cw mode, the max power in pulsed mode is definitely higher, and surely depends on the pulse width (e.g. could be 1 kW for a 10us pulse). Is there a rough rule of thumb to figure this out without having to test it directly and risk blowing up the amp? The amp design is based on the RF power mosfet MRF151G (the tech specs do not say anything about pulsed mode ratings). thanks.

CW mode for a tube would mean it is operating in Class C, not a linear mode. Your question makes no sense.

** The OP told just you it was a mosfet RF amp, a dual mosfet in fact, that operates in class AB.

How much clearer can it get?

** No - your reply is senseless.

Are you also cross-eyed or dyslectic?
