ECE 5613 RF/Microwave Circuit Design Laboratory Matching Networks and Tuning Stubs Lab 1. Quarter-Wave Matching Network There is a PC board in the toolbox, which is made to match a 25-ohm resistor to a 50-ohm line at 2 GHz. Measure and model this circuit. Does this circuit behave as expected? Explain your answer both qualitatively and quantitatively. 2. Asymmetric Stubs Another PC Board in the toolbox was made to zero the conductance of a 5.6nH inductor at 1.25GHz. Measure and model the circuit. Does this circuit behave as expected? Modify the circuit with copper tape to tune to the correct frequency if necessary. Document your tuned asymmetric stub-matching network. Write down the dimension of the circuit after tuning. 3. Symmetric Stubs A 5.6nH inductor with symmetric stub is also in the toolbox. Measure the physical dimensions of the stub. Analytically, calculate the frequency at which this stub-inductor combination should look like zero conductance. Now measure the [S] parameters of the device with the network analyzer. Do your analytical results make sense? Jan03 Drayton
