Lab1Designing of Matching Networks

The objective of designing of matching networks is to transfer maximum power to load at the desired RF frequency i.e. 2.07 GHz in this experiment. To Transfer all the power to load, it is required that the matching network is lossless.

Figure shows L section matching network with circuit diagram, input impedance, scattering parameters and related calculations.

Here Zs = 50 ohm and Z(load) = 75 ohm
