"Dr. Slick" wrote in message om... (Tdonaly) wrote in message ... Zo doesn't have to be the coax impedance. It can be any impedance you want. What about interstage-matching networks between FETs? Do you think there are no reflections there? Should you attempt to match impedances there? I would think so. You transform the input impedance of the driven stage to the optimum load of the driving stage. Whether that results in a conjugate match is completely immaterial. Trust me, I have done it . As for the Zo thing, you are trying to misapply the formula. BTW, the one place where you would think conjugate matching should always apply, antenna to receiver input, does not (always). Lowest noise figure often occurs at SWRs around 1.5 Tam/WB2TT |
