Enhanced Frequency-Dependent Noise Modeling for
Amplifier and Mixer Blocks
The RF Blockset™ amplifier and mixer blocks from the Physical library now
support m ore advanced calculations of nonlinear effects. In particular, this
enhances the behavior of the following blocks:

• S-Parameters Amplifier and S-Parameters Mixer
• Y-Parameters Amplifier and Y-Parameters Mixer

New Option for Interpreting the Simulink Signal as
the Incident Power Wave
The Input Port block now provides the option to interpret the input Simulink
signal as the incident power wave. This is the most co mmon RF modeling
interpretation. To select this option, use the new Treat Simulink signal
as parameter.
Enhanced Dielectric Loss Model in Three Transmission
Line Blocks
The following blocks now provide a more realistic model for dielectric loss:
• Coaxial Transmission Line
• Two-Wire Transmission Line
• Parallel-Plate Transmission Line
7
RF Blockset™ Release Notes
To specify dielectric loss, you use a new parameter, Loss tangent.This
parameter replaces the Conductivity in dielectric parameter.
Compatibility Considerations
Your existing models that include blocks with a nonzero value for the
Conductivity in dielectric parameter no longer model dielectric loss.
Instead, the models issue a warning message and use the default value of zero
for the Loss tangent parameter when you run the model.

Baseband-Equivalent Modeling Enhanced
Two new Input Port block parameters provide better control of
baseband-equivalent modeling:
• Fractional bandwidth of guard bands lets you specify Tukey windowing
to reduce ringing and other artifacts in the baseband-equivalent model.
• Modeling delay (samples) lets you specify a delay to ensure that the
baseband-equivalent model has a causal response.
For more information about these parameters and how to use them,
see the Input Port block referencepageand“CreatingaComplex
Baseband-Equivalent Model”.

RF Blockset™ Release Notes
Note If you create a model using RF Blockset Version 2.2 and run it in
previous versions of the software, two things happen:
• The blockset issues wa rn in gs ind icating that the Input Port block does not
have these two parameters.
• The blockset ignores the values of these two parameters, and uses their
default values.
To avoid these warnings, use the Simulink Save As option to save the model
in an earlier format, as described in “Saving a Model in an Earlier Simulink
Version” in the Simulink documentation.

The Touchstone®Data File for 2-Port Bandpass Filter demo now uses more

Output for Generic Real-Time (GRT) Targets Now

You can use Real-Time Workshop®software with RF Blockset software to
generate standalone executables for GRT targets.
Nonlinear Modeling of Physical Mixers and Amplifers
Improved
Previously, the nonlinear algorithm that was used by the physical mixer and
amplifier blocks was appropriate only for high-powered amplifiers (HPAs),
which operate close to the saturation point. The new nonlinear algorithm can
also be used for mixers and amplifiers that operate far below the saturation
point and yield very weak intermodulation products.
23
RF Blockset™ Release Notes
As with the old algorithm, the saturated output power of the new algorithm is
8.3 dB below the third-order output intercept point (OIP3).
Where the previous algorithm was pi ecew ise linear, the new nonlinear
algorithm uses a linear plus cubic curve of amplitude-in versus amplitude-out
to simulate the behavior of systems that operate far below the saturation
point. Where the previous algorithm assumed a third-order intercept point
(IP3) reference impedance of 50 ohm that was irrespective of the S-parameter
reference impedance, the new algorithm assumes that the S-parameter
reference impedance is the same as the IP3 reference impedance used to
convert from IP3 to the amplitude-related constants in the model.
Note The corresponding Z and Y algorithms still assume a fixed 50-ohm
conversion factor from specified power to modeled amplitude.

Introduction to RF Blockset Software
RF Blockset software is a tool for design, analysis, and simulation of RF
communications systems. It uses baseband-equivalent behavioral modeling to
modelandanalyzeRFsystemsinthetimedomain.
The blockset lets you assemble complex RF systems from libraries of RF
components such as ladder filters, transmission lines, black box elements,
amplifiers, and mixers. You can include Simulink, Signal Processing
Blockset™, and Communications Blockset blocks in your model, as w ell as
blocks from other MathWorks blocksets.
RF Blockset software works with RF Toolbox software. You can create
complex topologies with the toolbox, and then use them in RF Blockset blocks
for inclusion in an RF model.
RF Blockset Libraries
In R F Blockset software, blocks are divided into two categories:

RF Blockset™ Release Notes
• Physical — Blocks that model physical and electrical components in terms
of geometry, physical interactions, and measured data
• Mathematical — Blocks that model components in terms of mathematical
relationships
The Physical library includes the following sublibraries. Use blocks from
these libraries to model the physical or electrical structure of portions of an
RF system.
• Amplifiers — RF a mplifiers described by S-, Y-, or Z-parameters, noise
figure, and IP3, or a data file containing these parameters
• Ladder Filters — RF filters whose network parameters can be calculated
from their topologies
• Mixers — RF mixers described by S-, Y-, or Z-parameters and phase nois e,
or a data file containing these parameters
• Transmission Lines — RF filters whose network parameters can be
calculated from their geometry
28
• Black Box Elements — Passive RF components described by S-, Y-, or
Z-parameters, or a data file containing these parameters
• Input/Output Ports — Blocks that conne ct mathematical portions of
the model to the physical portions. Mathematical portions of the model
may also include blocks from Simulink and other blocksets that describe
components in mathematical terms.
Note You must use the Input Port and the Output Port blocks to bound a
physical system. They convert mathematical Simulink signals to and from the
RF Blockset physica l modeling environment. This lets you include physical
and mathematical blocks in the same model.
The Mathematical library includes amplifier, mixer, and filter blocks.
These blocks provide mathematical equivalents of the RF components.
Mathematical portions of an RF model may also include other Simulink
blocks that describe components mathematically.
