![]() Draw the topology of the matching network. It is easier to add impedances when elements are in series see Figure 1. The matching network must block DC current. Impedance and Admittance on Smith Chart Milica Markovic Brief review of impedance and admittance Impedance’s Z R+jX Z R + j X real part is called resistance R R, and the imaginary part is called reactance X X. Derivation of Smith Chart Equations The relationship between impedance and reflection coefficient is given by: o 1(z) Z(z) Z 1(z) + (1) where Zois the characteristic impedance of the system. Another way to read the admittances on the Smith chart is to use combination of impedance/admittance (Z/I) chart, Figure fig:SCDerscadmimp1. ![]() What is the \(Q\) of the matching network?.The imaginary part of YL is written as S, and is known as the susceptance. The real part of YL is written as C, and is known as the conductance. \) 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. In equation 1, YL is the admittance of the load, which is the inverse of the impedance of the load (ZL).
