Part I. Design a 10-dB microstrip line ( Z0 50 ) directional coupler at frequency f 2.5GHz . Your circuit topology can be chosen as needed.
Part II. Design a circuit to convert unbalanced microstrip line ( Z0 50 ) to a balanced line using the design topology in Fig. 6.44(a), page 235. Use frequency f 2.5GHz . The bending, angles, curves, distances are all design parameters that must be selected carefully to obtain the best possible solution. You must verify your final design as discussed in class.
