For a RF amplifier, S11 is the input impedance, S22 is the output impedance, S21 is the gain of the amplifier and S12 is close to 0. The Number_of_terminals entry in the Interconnect Model shall be an integer equal to N. Terminal rules are described below: • For an Interconnect Model with N ports, the Terminals and Ports are associated as follows: o Terminal Port o 1 1 … If the s-parameter is not fully defined for each of the ports combination, the default value 0 will be used for undefined ones. If the circuit is symmetrical, then S11=S22 and S12=S21, so only one measurement need be done. S1 corresponds to the voltage reflection coefficient of the device. So S21 is a measure of the signal coming out port 2 relative to the RF stimulus entering port 1. Note the port names "G" and "D" instead of "1" and "2". We will get the following set of two equations by considering the variables V1 & V2 as dependent and I1 & I2 as independent. A two-port device has four S-parameters. S parameters are complex numbers that characterize a device. Because impedance changes along the interconnect cause reflected waves, return loss is very sensitive to the interconnect’s impedance profile. Making measurements directly on a data file. A two port device is characterized by a 2 x 2 matrix of S parameters. Figure 1: Set up for measuring S-Parameter S11 and S12. Following are the types of S parameter measurements carried out. We use security software from Security and Privacy Software. If ZL = Zo, 2 2 L 0 a b Γ== so, therefore a2 = 0 if port 2 is terminated in Zo. The S-parameter matrix can be used to describe networks with an arbitrary number of ports. 2 Port S Parameters. The excitation frequencies are selected so that the TE 10 mode is the only propagating mode through the rectangular waveguide.

Refl ection coeffi cient Γ has the following relationship with impedance Z and admittance Y, which is also a 1-port parameter. If the number of output port is n1: The numbering convention for S-parameters is that the first number following the “S” is the port where the signal emerges, and the second number is the port where the signal is applied. The S-parameter for a 1-port network is given by a simple 1 × 1 matrix of the form $${\displaystyle (s_{nn})\,}$$ where n is the allocated port number. Out of which, we can choose two variables as independent and another two variables as dependent. The formalism of S-parameters describes the combination of sine waves scattered from the ports of an interconnect. The S-parameter universe is defined around the power waves that are incident to a port (‘a’) and the reflected wave ('b'), instead of talking about voltages and currents. Do you have a great idea about this? There are four variables V 1, V 2, I 1 and I 2 in a two port network as shown in the figure.
