You can build RF receivers and transmitters by connecting blocks from the SimRF libraries. SimRF provides two modeling libraries for describing RF systems at different abstraction levels. The Equivalent Baseband library is suitable for digital signal processing engineers to estimate the impact of RF phenomena on the overall system performances. RF designers use the Circuit Envelope library to refine transceiver architectures with increased modeling fidelity.
You can use SimRF to build system-level executable specifications and perform what-if analyses with different RF front-end architectures, or you can commit to a particular architecture and use simulation to develop digital signal processing algorithms to mitigate the RF impairments.
With SimRF, you can refine the executable specifications of the RF subsystem by adopting a top-down design methodology. This improves the communication between system architects and RF or analog engineers.
The circuit envelope solver enables the simulation of networks with arbitrary topologies. In the illustration, N-port S-parameter blocks are used to model 3-port combiners. These blocks read standard Touchstone
.snp files containing measured or simulated component data.
