1. Simple LC L-Match
If we want to use a simple LC L-Match matching network to convert a 50ohm load to a 5ohm resistor, what are the two possible configurations? Please complete the design by drawing the schematic and calculating all the design parameters. Assume that the operating frequency is
10GHz.
2. S-parameters of Passive Networks
Calculate the S-parameters of the following three circuits. Assume that the characteristic impedance is 50ohm.
3. S-parameters of Active Circuits
Calculate the S-parameters of the following three circuits. Assume that the characteristic impedance is R0. Assume there is no channel length modulation and body effect.
