New Functions for Converting 4N-Port S-Parameter
Matrices
There are two new functions for converting between 4N-port single-ended
S-parameter matrices and 2N-port mixed-mode S-parameter matrices:
• The
s2smm function lets you convert 4N-port single-ended S-parameters
to 2N-port mixed-mode S-parameters. You can view the 2N-port output
data to see interactions, such as crosstalk, that are not apparent in the
single-ended data. This lets you easily select the ports of interest for
further analysis.
• The
smm2s function lets you convert 2N-port mix ed-mo de S-parameters to
4N-port single-ended S-parameters.
Enhanced Dielectric Loss Model in Three Transmission
Line Objects
The following objects now provide a more realistic model for dielectric loss:

RF Toolbox™ Release Notes
• rfckt.coaxial
• rfckt.twowire
• rfckt.parallelplate
To specify dielectric loss, you use a new property, LossTangent. This property
replaces the
SigmaDiel parameter.
Compatibility Considerations
Your existing objects with a nonzero value for the SigmaDiel parameter no
longer model dielectric loss. Instead, the objects issue a warning message and
use the default value of zero for the
the
analyze method.

Demos Added
Two new demos show how to design broadband impedance matching networks

subsequent N-port device in the cascade. For more information about the

Introduction to RF Toolbox Software
RF Toolbox™ software lets you create and combine RF circuits for simulation
in the frequency domain with support for both nonlinear and noise data. You
can read, write, analyze, combine, and visualize RF network parameters.
The toolbox enables you to
• Work directly with network parameter data.
26
• Model RF networks.
• Analyze circuits interactively.
RF Circuits
The toolbox provides classes that let you model these circuit objects and
networks.
• Passive networks
• Amplifiers and mixers
Version 1.0 (R14) RF Toolbox™ Software
• Transmission lines: coaxial, coplanar waveguide, general transmission,
microstrip, parallel-plate, and two-wire
• SeriesRLC and shuntRLC circuits
• LC ladder filters: LC bandpass pi, LC bandpass tee, LC bandstop pi, LC
bandstop tee, LC highpass pi, LC highpass tee, LC lowpass pi, and LC
lowpass tee
• Networks: cascade, hybrid, parallel, and series
You can also model general circuit elements from data files.
Data Visualization
The toolbox lets you plot the network parameters of the circuits you create.
You can generate an X-Y plane plot, polar plane plot, or Smith Chart of one
or more selected network parameters directly from your data. You can also
generate these plots from circuit objectsyoucreateusingthetoolbox. See“RF
Circuit Objects” and “RF Data Objects” for information.
Data Format Support
The toolbox supports the Touchstone SnP, YnP, ZnP, and HnP data file
formats. It also introduces the MathWorks AMP format for amplifier data.
For more information about this format, see “AMP File Format”.
RF Analysis GUI
RF Tool is an RF analysis GUI that provides a visual interface for creating
and analyzing RF (radio frequency) components and networks. You can create
RF circuits quickly with the GUI. You can also import and export circuits
from the MATLAB workspace and RF data files.
RF Tool also provides the ability to set circuit parameters, analyze circuits,
view their resulting S-parameter data, and visualize the data using X-Y plane
plots, polar plane plots, and Smith Charts.
