New Circuit Envelope Library

SimRF 3.0 software introduces Circuit Envelope Elements, Sources, and Utilities libraries, which contain:

• Capacitor, Inductor, Resistor, and Impedance blocks that can connect in any configuration.

• A 2-port Amplifier block and a 3-port Mixer block, which support second-order and third-order nonlinearity modeling.

• An S-Parameters block for modeling black-box elements with up to four ports.

• Continuous Wave, Sinusoid, and Noise current and voltage sources that can model signals at multiple carrier frequencies simultaneously.

• A SimRF Outport block for probing signals from any location in an RF network.

For a full list of SimRF Circuit Envelope library blocks, see the SimRF Reference documentation.

New Circuit-Envelope Simulation Environment

SimRF 3.0 software introduces circuit-envelope simulation of RF systems into the Simulink environment. SimRF circuit-envelope simulation technology is built on the Simscape™ platform. All blocks in the SimRF Circuit Envelope library support the features available in the SimRF environment. For an introduction to circuit-envelope simulation, see the SimRF Getting Started Guide.

Compatibility Considerations

SimRF circuit-envelope simulation software diverges from the baseband-equivalent simulation technology of RF Blockset™ version 2.5.1 and earlier. In SimRF version 3.0, RF Blockset software is part of SimRF software. RF Blockset Mathematical and Physical libraries have been renamed SimRF Equivalent Baseband and Idealized Baseband libraries.

• SimRF Circuit Envelope library blocks have different product dependencies than Equivalent Baseband and Idealized Baseband library blocks. To run models with Equivalent Baseband or Idealized Baseband library blocks, you must install DSP System Toolbox software. See Working with SimRF Software for more information on SimRF product dependencies.

• SimRF Equivalent Baseband library and Idealized Baseband library blocks do not support features of the SimRF environment, such as multi-carrier simulation, signal probing, or general network topologies.

• Blocks in the SimRF Circuit Envelope library do not connect to blocks in the Equivalent Baseband library or Idealized Baseband library. To pass data between these blocks, convert signals from SimRF Circuit Envelope and Equivalent Baseband library blocks to Simulink signals using:

  • Circuit Envelope library SimRF Inport and SimRF Outport blocks.

  • Equivalent Baseband library Input Port and Output Port blocks.

• If you have Signal Processing Blockset™ installed, models built in RF Blockset version 2.5.1 run in SimRF version 3.0.

• RF Blockset version 2.5.1 documentation is contained within the SimRF documentation.

New RF System Demos

SimRF version 3.0 introduces eight new demos:

• AC Analysis of an RF System

• Architectural Design of a Low-IF Receiver System

• Executable Specification of a Direct Conversion Receiver

• Frequency Response of an RF Transmit/Receive Duplex Filter

• Impact of an RF Receiver on Communication System Performance

• Measuring Image Rejection Ratio in Receivers

• Two-Tone Envelope Analysis Using Real Signals

• Validating IP2/IP3 Using Complex Signals
