In this section you will simulate in ADS the quarter-wave transformer match- ing network that you designed in pre-lab. Figure 4.1: Quarter-Wave matching network. Build the circuit shown in Fig.4.1 in ADS. Note that the characteris- tic impedance of the quarter-wave section has been left blank. Be sure to enter the value that you have obtained from pre-lab section into your own schematic. Simulate the circuit, and then generate a plot to demonstrate the magnitude of the refection coecient (S11) vs. frequency over the frequency range from 100MHz to 1000MHz. When you plot the S11 for the quarter-wave transformer matching net- work, you should see additional frequencies at which the load is matched to the source. Why is that happening?
