The MathWorks announces the RF Blockset and the RF Toolbox, two products designed to expand the scope of model-based design for signal processing and communications engineering applications. Both products enhance the functionality of the MathWorks industry-leading software platforms, MATLAB(r) and Simulink®, by providing users with a features for RF system design, analysis, development, and implementation. The blockset works within the Simulink environment and offers users a library of blocks to model the behavior of RF amplifiers, mixers, filters, and transmission lines. Using the blockset, system architects can apply model-based design to develop commercial and defense wireless communication systems and semiconductors faster and more efficiently. Engineers can validate a working model in Simulink and then use that model as an executable specification to verify design and implementation. The toolbox extends the MATLAB technical computing environment by providing users with pre-built design and analysis functions and a graphical tool for working with, analyzing, and visualizing the behavior of RF components. With the toolbox, RF engineers can now access industry standard data files and work with network parameters in MATLAB to manipulate data and visualize results of analysis, thereby eliminating error-prone manual calculations.
