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 model and analyze RF systems in the time domain.

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 well 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 RF Blockset software, blocks are divided into two categories:

• 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 amplifiers 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 noise, or a data file containing these parameters

• Transmission Lines — RF filters whose network parameters can be calculated from their geometry

• 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 connect 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 physical 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.

Data Visualization

RF Blockset software lets you plot the network parameters of the component blocks in the Physical library. For each such block, you can generate an X-Y plane plot, polar plane plot, or Smith^® Chart of selected network parameters in a specified frequency range. The dialog box for each block contains the parameters you need to specify the plot.

The blockset also provides a composite plot which includes four separate plots in one figure. This predefined combination of plots differs based on the type of block.

Data Format Support

RF Blockset software supports the Touchstone S2P, Y2P, Z2P, and H2P data file formats. It also introduces the MathWorks AMP format for amplifier data. The AMP format is intended for use as input to the General Amplifier block. For more information about the AMP format, see AMP File Format in the RF Toolbox documentation.

Demos

Demos are available on the Demos tab of the MATLAB Help browser. These demos show examples of linear filtering and nonlinear amplification, as well as transmitters and receivers.
