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.
