Since your circuit is a one-port, you will have the S11-parameter only. In the third tab of the dialog, Output, go to the "Parameter Set" section and choose the S radio button to compute the scattering parameters. This will provide a smooth graph of the port characteristics. Select a linear scale interval and set the step size to 10MHz. In the second tab, Sweep, set the start and stop frequencies to 1GHz and 5GHz, respectively. Accept the default value of 50Ω for the "Reference Impedance". In this case, Port 1 is defined between Node 2 and the ground. In the first tab, Connections, you define the port(s) of your circuit. It has three tabs at the top: Connections, Sweep and Output. In the Toolbox, select the Test Panel and check the "Network Analysis" checkbox. In this case, you will define a one-port network with an input port established at the input of the T-Line between Node 2 and ground. Network analysis calculates the S/Z/Y parameters of your circuit based on the port(s) you define for your RF circuit. Running a Network Analysis of Your RF CircuitĪs a first step, you will run a "Network Analysis" test of your RF circuit. The quarter-wave impedance transformer circuit tuned for f 0 = 2GHz.
