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 transmitters and receivers in communication and radar systems. You can connect blocks arbitrarily to form diverse architectures and simulate the system-level behavior of the RF front end.
SimRF lets you simulate RF amplifiers to estimate gain, noise, even-order, and odd-order intermodulation distortion. You can simulate mixers to predict image rejection, reciprocal mixing, local oscillator phase offsets, and DC conversion. You can also simulate frequency-dependent impedance mismatches between linear and nonlinear components in the time and frequency domains. The RF Budget Analyzer app lets you generate test benches to validate your transmitter or receiver performance and automatically set up a circuit envelope simulation.
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.
