The S-parameters of a transistor measured at 1 GHz are given below (Zo at both ports is 50 (2) 1. Is this network lossless, reciprocal? 2. Calculate the input impedance if the 2nd port is loaded by 20-j52 Ohm (hint: L4-40). 3. Design a microstrip matching network (using series line and open shunt stub) to match this input impedance to 50 N using Smith chart, calculate the length and width of the microstrip lines for alumina board with &q=9.8 and thickness d=0.127 cm (assume other parameters ideal). Verify your solution in ADS 4. Is there an easier way to match this impedance using L and/or C? Calculate the value of this L and/or C? 5. Calculate the input impedance if the 2nd port is loaded by 10+j100 Ohm.
