Feed-Line Impedance MatchingAugust 31st Fact-of-the-Day
Engineers discovered long ago that any electrical circuit that can be constructed from a finite number of lumped inductor and/or capacitor elements has an impedance that is a rational function of frequency (i.e., an impedance that changes with frequency). Because of that, no finite network composed of inductors, capacitors or inductors and capacitors can match the characteristic impedance of a transmission line over a band of frequencies. ©2004 Martek, International.
