The fоllоwing infоrmаtion аpplies to Questions 1 through 8. A single shunt open-circuit (OC) stub is to be used to mаtch a load impedance (ZL) to a 50 Ω system impedance. Refer to the schematic below captured from ADS. The main goal of this set of problems is to determine the length of the stub (parameter 'E' of TL2 in the schematic) as well as the distance between the load and the connection point of the stub (parameter 'E' of TL1 in the schematic). (Notice that these quantities have been left blank in the schematic captured from ADS.) The load impedance consists of a parallel RL (R = 100 ohms and L = 3.9 nH). Assume a frequency of 3.8 GHz. First, let's find the real and imaginary parts of the load admittance. Begin by evaluating the real part of . Type your answer in milli-siemens (mS) to two places after the decimal. Hint:
