General Circuit Element

Model two-port network described by rfckt object

  • Library:
  • RF Blockset / Equivalent Baseband / Black Box Elements

  • General Circuit Element block

Description

The General Circuit Element block models the two-port network described by an RF Toolbox™ circuit (rfckt) object.

The block uses the rfckt/analyze method to calculate the network parameters at the modeling frequencies.

Parameters

Main

RFCKT object that contains circuit element device data, specified as an any RF Toolbox rfckt object that creates a default circuit object of the specified type, or a MATLAB® expression that generates such an object. See RF Circuit Objects for more information about circuit objects.

Visualization

Frequency data source, specified as User-specified.

Frequency data range, specified as a vector with each element unit in hertz.

Reference impedance, specified as a nonnegative scalar in ohms.

Type of data plot to visualize using the given data, specified as one of the following:

  • X-Y plane — Generate a Cartesian plot of the data versus frequency. To create linear, semilog, or log-log plots, set the Y-axis scale and X-axis scale accordingly.

  • Composite data — Plot the composite data.

  • Polar plane — Generate a polar plot of the data. The block plots only the range of data corresponding to the specified frequencies.

  • Z smith chart, Y smith chart, and ZY smith chart — Generate a Smith® chart. The block plots only the range of data corresponding to the specified frequencies.

Type of S-Parameters to plot, specified as one of the following. When noise is spectral, NF plotting is possible.
