I have a couple questions, a few I guess. With an NPN and PNP transistor you can have a push pull amp. What is it called when you use two NPN transistors in the same configuration? I suppose the best you could do is class B amp only for this configuration using two NPN transistors, is this correct?
Also will the two NPN configuration get rid of even harmonics or do you really need an NPN and a PNP transistor push pull circuit to do that?
Can Mosfets be used efficiently to amplify digital television transmitter output to increase the power? Say two IRF 510's ? The amplifier I want to design is for 69 MHz and will amplify a digital TV transmitter signal. One of low power in case you were wondering, to about 3-5 watts output. Input to this amp will be about .5 watts maybe less. It will run on 28 volts. Do I really need to run a digital TV signal through a class A amplifier? I know class B does work but I am wondering how well. Any insight into this will help me. I am new to amplifying digital signals and can't seem to find the info I need to read about it. I cant determine what class of amplifier I need for digital television. Yes I'm an old timer needing to fire up a new fire in my brain when I thought it was over. Yes I feel stupid asking and I can take criticism, but looking for some brilliant person to discuss this for me. Explain away, as I love picking others brains.
