Unformatted text preview: (b) Let the microstrip substrate have a height h = 2 mils and a relative dielectric constant of ε r = 4.3. Use the low loss approximation to calculate the attenuation constant (Np/m) versus frequency from dc to 10 GHz. 3) (a) A two port circuit is characterized by its ABCD parameters. For the circuit below, calculate the input impedance, Z in, seen by the source. V g Z s Z L A B C D I 1 I 2 + V 1+ V 2Z in (b) Find V 2 in terms of V g , Z in , Z S and the ABCD parameters. 4) (a) A two port network is characterized by its scattering parameters. For the circuit below S 11 S 12 S 21 S 22 V 1 + V 2V 1V 2 + The reference impedance for the Sparameters is Z o . Calculate the load voltage, V 2 when Z L = Z o.
