hello
i am testing an hf amp with low cost mosfets in AB class push pull.
mosfets are IRFP150.
i have a power consumption of 11 amperes at 12 volts.
my power bridge shows 200 watts output power at a 50Ω dummy load.
frequency is 1.8 MHz.input power 5 watts with AM or FM modulation.
How is that possible?
