Design and simulate RF systems

RF Blockset™ (formerly SimRF™) provides a Simulink® model library and simulation engine for designing RF communications and radar systems.

RF Blockset lets you simulate nonlinear RF amplifiers and model memory effects to estimate gain, noise, even-order, and odd-order intermodulation distortion. You can model RF mixers to predict image rejection, reciprocal mixing, local oscillator phase noise, and DC offset. You can also simulate frequency-dependent impedance mismatches. RF models can be characterized using data sheet specifications or measured data, and can be used to accurately simulate adaptive architectures, including automatic gain control (AGC) and digital predistortion (DPD) algorithms.

The RF Budget Analyzer app lets you automatically generate transceiver models and measurement test benches to validate performance and set up a circuit envelope multicarrier simulation.

With RF Blockset you can model RF systems at different levels of abstraction. Circuit envelope simulation enables high-fidelity, multicarrier simulation of networks with arbitrary topologies. The Equivalent Baseband library enables fast, discrete-time simulation of single-carrier cascaded systems.
