Question

Question: 1. Two types of Ell matching networks are shown in Fig. P2.12. Select one that can match the load Y_LOAD = (8 - j12) X 10^-3 S to a 50-Ω transmission line. Find the element values at f =1 GHz.

2. Show the impedance-admittance path in the ZY Smith chart for the circuit shown in Fig. P2.13 at ω =109 rad/s, and evaluate Z_IN.
