I'd just like to check my understanding: I assume that Smith Charts are not used to design impedance transforming circuits for LC filters because LC filters are designed with a nominal impedance in mind (nominally 50 ohms). Is this correct?
(The reason I ask: I have built a LC low pass filter (7th order Chebyshev) and the Smith chart (from a NanoVNA) shows that the impedance of the filter varies with frequency - which I think makes sense because the output of the filter will be the result of the complex impedances of each component.)
