A 500 source is connected to a load, which is composed of simple RLC in parallel, with R = 6092, L = 5nH, and C= 0.2 pF. (a) Plot the impedance loci on a Smith chart (i.e., I plane) for the frequency range of 3 to 7 GHz. (b) Use computer to plot the VSWR for the frequency range of 3 to 7 GHz. A transmission-line section (with an electrical length of 180 at 5GHz and characteristic impedance Zo) is inserted between the load and the 50 source to improve the input VSWR. This is accomplished by first : (c) derive the exact expression of the input VSWR. Then, (d) use trial-and-error procedure to determine the optimum value of Z, such that the VSWR at the frequency range of 3 GHz to 7 GHz is lowest. What it this optimum value? (e) Use computer to plot the input VSWR of this design for the frequency range of 3 to 7 GHz. (f) Plot the input impedance loci of this design on a Smith chart (i.e., I plane) for the frequency range of 3 GHz to 7 GHz.
