Description

The Shunt RLC block models the shunt RLC network described in the block dialog box, in terms of its frequency-dependent S-parameters.

For the given resistance, inductance, and capacitance, the block first calculates the ABCD-parameters at each frequency contained in the vector of modeling frequencies, and then converts the ABCD-parameters to S-parameters using the RF Toolbox™ `abcd2s` function. See the Output Port block reference page for information about determining the modeling frequencies.

For this circuit, A = 1, B = 0, C = Y, and D = 1, where

$Y=\frac{-LC{\omega }^{2}+j\left(L/R\right)\omega +1}{jL\omega }$

and $\omega =2\pi f$.

The shunt RLC object is a two-port network as shown in the following circuit diagram.
