Prоblem D.1 (2 pоints) A 75 Ω lоаd is connected to а 10 GHz source with impedаnce of 20 Ω. Design a matching network to ensure maximum power transfer to the load. Assume that any transmission lines in the matching network are made using an insulator with dielectric constant of 6. Problem D.2 (5 points) Find the input impedance of the following transmission line structure at 1 GHz. Note that the lengths of the transmission lines are expressed as electrical lengths for some sections. Problem D.3 (8 points) A 100-80j Ω load is connected to a transmission line with characteristic impedance of 20Ω. The operating frequency is 2 GHz and the transmission line is made of a lossless insulator with dielectric constant of 4. Using the Smith Chart provided, answer the following: (a) Plot the load (1point) (b) Determine the reflection coefficient at the load (1 point) (c) Determine the VSWR (1 point) (d) If the length of the transmission line is 0.6λ, determine the input impedance (2 points) (e) Instead of the 0.6λ length, if the length of the transmission line is 4cm, determine the input impedance. (2 points) (f) Where does a short circuit lie on the Smith Chart? (1 point)
