In short, we can derive the input impedance that gets presented at the left-hand end of the line versus the line’s length for the upper schematic of Figure 2. It happens to turn out that using the ...

Input impedance of a transmission line, open at the far end. As we go to even higher and higher frequencies, the input impedance of the transmission line will oscillate between really high impedance ...

That impedance is usually the characteristic impedance of a transmission line you’re using or the input and output impedance of a filter or impedance-matching circuit to be created. Most RF ...

SAW filters are *notoriously* sensitive to broadband input and output termination impedance. It would be interesting to see an S21 plot of this board with both ideal and nonideal transmission line ...
