The document reports on three labs for designing matching networks. The first lab describes designing an L-section matching network to transfer maximum power at 2.07 GHz between a 50 ohm input and 75 ohm load. The second lab involves designing tapped inductors and capacitors to match 50 ohm and 75 ohm impedances. The third lab designs a tapped resonator matching network for a 75 ohm load and 50 ohm input. Diagrams, results and calculations are presented for each matching network design.

Designing 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

Designing of Tapped Inductor and Capacitor
Tapped Capacitor and Tapped inductor are another important circuits
for impedance matching in which four parameters are unknown such as
L1, L2 and C as shown in figure 24 with RL=50 ohm and Rin=75 ohm.
