Unfortunately, it makes a terrible mess of any modulation
------------------------- Reg, Well not ANY modulation, just signals with amplitude modulation components. But this is a well-known property of Class C amplifiers, so what's the point?. If we want to talk about Class B or Class A, we should start a new thread. Joe W3JDR "Reg Edwards" wrote in message ... The 'power dissipation' in a Cass C stage is primarily a function of what percentage of the cycle the stage is neither in saturation nor cutoff. A perfectly rectangular output switching waveform of any duty cycle , if it could be achieved, would result in nearly 100% efficiency. Joe W3JDR =================================== Unfortunately, it makes a terrible mess of any modulation. To avoid distortion and non-linearity, saturation can be permitted only on the extreme peaks of the modulated driving waveform. Class-C is ruled out. Class-B or Class-AB prevails. ---- Reg. |
