I did comment on 2 as an explanation, one which I think is poor because of the conclusions that might be drawn from it, eg any mismatch creates reflected power which must be dissipated in the PA. I did suggest that in the steady state, in a tx-line-load scenario, the impedance looking into the line can be found, and that equivalent load adequately explains the PA's behaviour. You may have struggled with others over this in times past, but by your own descriptions they had little intellectual horsepower, and less experience in the matter. I never said such a thing, if it is your conclusion, I disagree with it. .... Owen |

Hi Owen, It is surprising the conclusions I've drawn from our correspondence then. As I've steadfastly expressed nearly every posting in these terms, you have not exactly responded to my misunderstanding in an uniform manner. I shall return to those postings to enquire further rather than laboring the point here. I did comment on 2 as an explanation, one which I think is poor because of the conclusions that might be drawn from it, eg any mismatch creates reflected power which must be dissipated in the PA. This is not a denial? I see no positive characteristic you have derived from 2 as allowing it is acceptable. I did suggest that in the steady state, in a tx-line-load scenario, the impedance looking into the line can be found, and that equivalent load adequately explains the PA's behaviour. Yes, this allowing reflected power in your terms, allowing you to express it as a fiction suitable to providing a truth in creating the lumped equivalent. This may have the heavy hand of my editorialization, but it is forced by the equivocation I find in your points I am responding to here. You may have struggled with others over this in times past, but by your own descriptions they had little intellectual horsepower, and less experience in the matter. I never said such a thing, if it is your conclusion, I disagree with it. As I have never raised the discussion of "others" or how "they" developed poor explanations or subscribed to faulty premises; then my perhaps over-arching characterization is what you are rejecting as your having said. You may note that at that time I explicitly offered that their contributions were not germane to the facts. 73's Richard Clark, KB7QHC |
