![]() Draw the topology of the matching network. That is, the set of all impedances given by zL R, where the. The point zL1-i is placed on the Smith Chart, which is at the intersection of the Re zL1 circle and the Im zL-1 curve. The matching network must block DC current. The Smith Chart has been in use since the 1930s as a method to solve various RF design problems - notably impedance matching with series and shunt components - and it provides a convenient way to find these solutions without the use of a calculator. The resulting curve for Im zL-1 is plotted in green in Figure 2.What is the \(Q\) of the matching network?. ![]() ![]() \) that will match a source with a Thevenin resistance of \(50\:\Omega\) to the input of an amplifier presenting a load resistance of \(200\:\Omega\) to the matching network. ![]()
