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.

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.
