Shunt stub design
WebElectrical Engineering questions and answers. Used Smith Chart for each problem 1 Design two lossless L-section matching circuits to match each of the following loads to a 100 ohm generator at 3 GHz. (a) ZL = 150 - 200 2 and (b) ZL = 20 - 290 ohm. 2 A load impedance ZL = 100 + j80 2 is to be matched to a 75 2 line using a single shunt-stub tuner. Web• Design a double-stub shunt tuner to match a load impedance ZL = 60 − j80 to a 50 Ω line. The stubs are to be open-circuited stubs and are spaced λ/8 apart. • Assuming that this load consists of a series resistor and capacitor and that the match frequency is 2 GHz, plot the reflection coefficient magnitude versus frequency from 1 to 3 GHz.
