Question: 1. Design two microstrip matching networks for an amplifier whose reflection coefficients at f = 800 MHz, in a 50-Ω system, are Γs = 0.8!160° and ΓL = 0.7!20° Show the diagram for the complete amplifier using balanced shunt stubs.
2. (a) Determine the value of Γs in Fig. P2.26a.
(b) Determine the value of Γs in Fig. P2.26b. Observe that the 100-pF capacitor is a short circuit to the ac signal.
