Introduction
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.
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 the recommended Communications System Toolbox™ and DSP System Toolbox™, respectively.
