Abstract
Impedance, Characteristic impedance, RF transmission line and VSWR are fundamental terms not only for the design of RF filters but also for all RF components and circuits. The terms are explained in detail with simple examples for physical understanding. Impedance is explained for a discrete reactive element circuit and for a single load resistor introducing the concept of distributed reactive elements. The construction and characteristics of coaxial, microstrip and stripline transmission lines are explained. VSWR is explained graphically with numerical examples for transmission line with open-circuited load, short-circuited load, matched load, infinitely long coaxial cable and partially matched load after explaining its practical significance.
