Hi
When I read the page on the link:
http://www.electronics-tutorials.com/amplifiers/negative-feedback.htm
I found this formula for calculating the output power of RF amplifier:
2 * Po = [Vcc - Ve][SUP]2[/SUP] / R
Also found the same formula in the book: ARRL - Experimental Methods in RF Design, where:
Po: the output power
VCC: the battery voltage
Ve: the emitter voltage
R: the load resistance
I think that number 2 came from a conversion of the Vp to rms
My question is: Why [Vcc - Ve][SUP]2[/SUP] and not simply Vc[SUP]2[/SUP] ; the ac collector voltage??
Thank you
