Unformatted text preview: ± ² 85 Ω . (a) Find l , the length of the nonquarter wavelength line in meters. Assume transmission lines are air filled. (b) Find ± Â , the characteristic impedance of the quarter wave line. (c) Find ¾¿ if the frequency is changed to 2 GHz but the length of the lines (in meters) and the source and load impedances remain fixed. Does the network still work? PROBLEM SET 4 Page 2 Autumn Quarter 2011 Problem 3 A single stub matching network is now used instead to provide an impedance match for the same load and source impedances as in problem two as shown. Assume all transmission lines to be used are air filled and have characteristic impedances of 85 ohms. (a) Find ± in meters. (b) Find ² in meters. (c) Calculate the time averaged power dissipated in the load with this network....
