What is RF Toolbox?

RF Toolbox™ provides functions, objects, and apps for designing, modeling, analyzing, and visualizing networks of radio frequency (RF) components. With this toolbox, you can work across different applications such as wireless communications systems, radar, and signal integrity for high-speed digital interconnects. The toolbox provides functions for analyzing, manipulating, and visualizing S-parameters. You can convert among S, Y, Z, T, and other network parameters and visualize the results using rectangular and polar plots, as well as Smith^® Charts. In addition, you can de-embed measurement test fixtures, check and enforce passivity and causality, and compute group delay and phase delay to study stability and dispersion.

RF Toolbox also includes the RF Budget Analyzer app, which enables you to analyze transceiver chains using Friis and harmonic balance in terms of noise, power, and nonlinearity. From these analyses, you can generate RF Blockset™ models that are ready for circuit envelope simulation and system-level integration in Simulink^®. Idealized baseband models of amplifiers, mixers, and other RF components enable estimating the impact of RF impairments such as noise and nonlinearity on system performance, for example, integrating with testbenches built with Communications Toolbox™ or Phased Array System Toolbox™.

RF Toolbox lets you build and analyze networks of RF components such as filters, transmission lines, matching networks, amplifiers, and mixers. These components can be defined using measurement data, including Touchstone^® files, or by specifying network parameters and physical properties. And, with the rational fitting method, you can identify an equivalent Laplace model of linear components such as interconnects and filters. These models can then be exported as Simulink and Simscape™ blocks, SPICE netlists, or Verilog^®-A modules for integration of frequency-dependent RF components into time-domain simulations.

With these capabilities, RF Toolbox helps engineers move from component-level measurements all the way through to system-level simulations. Our extensive documentation includes ready-to-use examples that you can copy straight into MATLAB^® to get up and running.
