Question

3) Double Stub Matching This problem will utilize a double stub tuner to match a load. The load impedance is given to be ZL=75 + j 75 [Q] and the

velocity of propagation is v = 3x10^® [m/s]. The first stub was placed a distance of d2 = 8*1/3 mm from the load. The separation of the stubs is given to be d2 = 1.875 cm. The transmitter is operating at 4 GHz. The characteristic impedance of the line and stubs are given to be Z = 50 Q. a) Use a Smith Chart to determine the required short circulated stub lengths. As before, explain all of your work.
