For each inductor and capacitor pair in the network, the block first calculates the ABCD-parameters at each frequency contained in the vector of modeling frequencies. For each series pair, A = 1, B = Z, C = 0, and D = 1, where Z is the impedance of the series pair. For each shunt pair, A = 1, B = 0, C = Y, and D = 1, where Y is the admittance of the shunt pair. The LC Bandstop Tee block then cascades the ABCD-parameters for each series and shunt pair at each of the modeling frequencies, and converts the cascaded parameters to S-parameters using the RF Toolbox abcd2s function. See the Output Port block for information about determining the modeling frequencies. The LC bandstop tee network object is a two-port network as shown in the following circuit diagram. L1 L3 C1 L2 C3 L4 C2 C4 [L1, L2, L3, L4, . . . ] is the value of the 'L' property, and [C1, C2, C3, C4, . . . ] is the value of the 'C' property. 5-106 LC Bandstop Tee Dialog Box Main Tab Inductance (H) Vector containing the inductances, in order from source to load, of all inductors in the network. The inductance vector must contain at least three elements. Capacitance (F) Vector containing the capacitances, in order from source to load, of all capacitors in the network. Its length must be equal to the length of the vector you provide in the Inductance parameter. All values must be strictly positive. 5-107 LC Bandstop Tee Visualization Tab For information about plotting the filter parameters, see Chapter 3, "Plotting Model Data".

The inductance vector must contain at least two elements. Capacitance (F) Vector containing the capacitances, in order from source to load, of all capacitors in the network. Its length must be equal to or one less than the length of the vector you provide in the Inductance parameter. [. . . ] · Thermal noise -- Use thermal noise to specify temperature-dependent random noise. · Phase noise -- Use the phase noise to specify noise to add to the angle component of the input signal. · Nonlinearity -- Use nonlinearity (specified as output power and phase as a function of input power and frequency in an AMP file or as third-order intercept point) to specify nonlinear mixer behavior as a function of input power. Note If you specify a nonzero value for the local oscillator frequency of the mixer and set the Type parameter to Upconverter, the blockset converts the signal to a frequency above the center frequency.
