SimRF
Design and simulate RF systems
SimRF™ provides a component library and simulation engine for designing RF systems. It includes amplifiers,
mixers, S-parameter blocks, and other basic blocks for designing architectures for wireless transceivers used in
communication and radar systems. You can connect these blocks arbitrarily to form diverse architectures and to
simulate the behavior of the RF front-end at the system level.
SimRF lets you simulate RF amplifiers to estimate gain, noise, even-order, and odd-order intermodulation
distortion. The simulation of mixers enables you to predict image rejection, reciprocal mixing, local oscillator
phase offsets, and DC conversion. You can also simulate frequency-dependent mismatches between linear and
nonlinear components in the time and frequency domains.
With SimRF you can model RF systems at different levels of abstraction. The circuit envelope solver enables
high-fidelity, multicarrier simulation of networks with arbitrary topologies. The Equivalent Baseband library
enables fast, discrete-time simulation of single-carrier cascaded systems.
Key Features
▪ Circuit envelope solver for multiple carrier-frequency simulation
▪ Arbitrary network descriptions, enabling N-port block modeling and intra-model signal probing
▪ S-parameter data files for time-domain and frequency-domain simulations
▪ Passive components, including resistors, capacitors, inductors, transmission lines, and general impedance
blocks
▪ 3-port mixer and 2-port amplifier models specified by noise figure, IP2, IP3, P1dB, and Psat
▪ Equivalent Baseband library for discrete-time simulation of single-carrier cascaded systems
SimRF works with Simscape™ to simulate the performance of the RF system defined by the block diagram.
Gateways to Simulink® enable signal generation and analysis features found in Communications System Toolbox™
and DSP System Toolbox™, respectively.
