I have an RF amplifier (GHz), 50W. Power source 28V. Please tell me how do they calculate output power? I know only 1 method: V^2/r.
So, if I try 28^2/50 I got 15W. But its 50W. Another words, if I have 50W and 50 Ohm load, I need amplitude about 50V. But the power source only 28V. How is it possible?
