Let's say source and load are 50 Ohm and the transmission line has a discontinuity near the beginning and near the end. Let's say these are very short and in-between the transmission line is back to 50 Ohm. Is this worse than if the discontinuity persisted in-between (as seen in the picture)?
Basically, if there is a discontinuity, for example an RF switch connector, does that become a major concern or is its impact negligible because it only exists in such a small portion of the transmission line? Or is it that anytime impedance changes, there is a reflection, so it doesn't matter at all if the discontinuity is long or short?
