MathWorks has launched SimRF, which provides a component library and circuit-envelope simulation engine for system-level design of RF communication systems. SimRF offers new circuit-envelope and harmonic balance simulation technology built on the Simscape platform for modeling RF system architectures. It provides a library of true-to-form multiport components and a simulation engine for designing RF systems, enabling architects to perform realistic, multifrequency simulations early in development and to make effective tradeoffs in designs that include digital and analog/RF components.

SimRF™ provides a component library and simulation engine for designing RF systems. It includes mixers, amplifiers, S-parameter blocks, and other basic blocks for architectural design and modeling of wireless transceivers. You can connect these components arbitrarily to form diverse architectures and to model system-level impairments. SimRF enables simulation of RF gain, noise, and intermodulation distortion commonly attributed to RF amplifiers. It provides circuit envelope technology for simulating RF impairments uniquely associated with mixers, including image rejection, reciprocal mixing, local oscillator phase offsets, DC conversion, and DC offsets. Equivalent baseband technology is also included, enabling fast simulation of single-carrier cascaded systems.

Features and Benefits:
- Multiple carrier-frequency models
- General N-port models and S-parameter data files
- Passive components, including resistors, capacitors, inductors, and general impedance blocks
- Weakly nonlinear 3-port mixers and 2-port amplifiers specified by noise figure, IP2, IP3, and data files
- Intra-model signal probing
- Circuit-envelope technology for high-fidelity simulation
- Equivalent baseband technology for fast simulation

SimRF is available now with U.S.list prices start at $3000. For more information, visit
