Shunt C
Model shunt capacitor
- Library:
RF Blockset / Equivalent Baseband / Series / Shunt RLC
Description
The Shunt C block models the series inductor described in the block dialog box, in terms of its frequency-dependent S-parameters
The shunt C object is a two-port network, as shown in the following circuit diagram.
Parameters
Main
Capacitance (F) — Capacitance of the shunt element
1e-12 (default) | scalar
Scalar value for the capacitance. The value must be non-negative.
Visualization
Source of frequency data — Frequency data source
User-specified (default)
When Source of frequency data is
User-specified, specify as a vector of
frequencies in the Frequency data parameter.
Frequency data — Frequency data range
[1e9:1e6:3e9] (default) | vector
Frequency data range, specified as a vector in hertz.
Dependencies
To set this parameter, first select
User-specified in Source of
amplifier gain. This selection activates the
Visualization Tab which contains
Source of frequency data
Reference impedance (ohms) — Reference impedance
50 (default) | scalar
Reference impedance of the coaxial transmission line, specified as a scalar in ohms.
Plot type — Type of data plot
X-Y plane (default) | Composite data | Polar plane | Z Smith chart | Y Smith chart | ZY Smith chart
Type of data plot that you want to produce with your data specified as :
X-Y plane— Generate a Cartesian plot of your data versus frequency. To create linear, semi-log, or log-log plots, set the Y scale and X scale accordingly.Composite data—The composite data plot automatically generates four separate plots in one figure window, showing the frequency dependence of several parameters.Polar plane— Generate a polar plot of your data. The block plots only the range of data corresponding to the specified frequencies.Z Smith chart,Y Smith chart, andZY Smith chart— Generate a Smith® chart of your data. The block plots only the range of data corresponding to the specified frequencies.
