ANSYS RF Option (now including Delcross EMIT)

The ANSYS RF Option combined with HFSS creates an end-to-end high-performance RF simulation flow. Its features include a harmonic balance circuit simulation for nonlinear amplifier analysis, a 2.5-D planar method of moments solver, filter synthesis plus DC, transient, oscillator, load-pull and envelope circuit analysis engines.

The ANSYS RF Option also includes EMIT, a unique multi-fidelity approach for predicting RF cosite interference to provide rapid identification and “root-cause” analysis of EMI issues in complex RF environments. EMIT manages RF system performance data, simulating the impact of EMI on system performance and mitigating EMI issues. This results in a complete model of the RF environment maintainable over the life of a system.

EMIT

ANSYS EMIT provides a unique multi-fidelity approach for predicting RF cosite interference to provide rapid identification and “root-cause” analysis of EMI issues in complex RF environments. EMIT provides a software framework for managing RF system performance data, simulating the impact of EMI on system performance, and mitigating EMI issues. This results in a complete model of the RF environment maintainable over the life of a system.

  • A complete RF co-site and antenna coexistence analysis environment
  • Automated diagnostics and visualization for rapid “root-cause” analysis
  • Quick assessment and comparison of potential mitigation measures
  • Built-in RF component library
    A built-in library that provides models of typical radios for military and commercial applications.
  • Multi-fidelity parametric radio models
    Parametric simulations providing meaningful results early in the design cycle from a minimal amount of radio system input data. These multi-fidelity parametric models reproduce radio performance characteristics comparable to measured responses.
  • Antenna-to-Antenna coupling models
    Supports touchstone file multi-port antenna isolation data. EMIT also includes several built-in antenna coupling models for early assessment of co-site EMI allowing for, in the absence of specific isolation data, determination of system specifications for antenna-to-antenna coupling
