Well, I may be wrong, but the relationship between duty cycle and fundamental harmonic of a rectangular signal should be of the sin(x) kind ( sin(x)/x should be the relationship between the order of
Varying the drive duty cycle to change the RF level does not give the result expected at first sight. While the DC level does vary proportional to the duty cycle, the RF carrier, which is revealed vi
Interesting idea, Johan, but I believe you'll find that if you drive the amplifiers with a sinewave, there is an efficiency penalty; whereas, if you drive them with a square wave, you actually have m
<< Another way to control the output power is to vary the phase of the driving signal to one of the sides of a full bridge amp'. Some kind of variable delay / phase shifter would do the trick. If the
I think the PA supply voltage is variable, but where does the "envelope" signal come from ? Another way to control the output power is to vary the phase of the driving signal to one of the sides of a
