RF desense is a critical design challenge faced by engineers creating wireless products. Due to miniaturization, faster digital signals, multiple wireless systems and radios operating simultaneously within a small footprint, the sensitivity of receivers is compromised significantly. These trends in the industry are causing engineers to demand a robust solution for RF desense. ANSYS HFSS and EMIT can help engineers diagnose and mitigate problems of RF desense in wireless electronic devices across a broad range of industries. These advanced simulation tools can analyze large, complex electronic devices with a multitude of signals and receivers, allowing you to run what-if scenarios and eliminate desense.
EMIT’s powerful system-level RF analysis tool lets you start with behavioral radio models from the built-in library and continuously enhance the model as better data becomes available during the design. EMIT’s advanced visualization and automated diagnostic capabilities help you identify and investigate all the sources of interference and study their effects on the victim receivers at various levels of granularity.
With ANSYS HFSS and SBR+ you can:
- RF system solver optimized for fast solution involving tens of millions of potential radio frequency interference (RFI) paths.
- Built-in standards-based radio library and RF components.
- Wideband models and analysis to include in-band and out-of-band interference, including nonlinear phenomena such as intermodulation, harmonics, spurious responses and broadband noise.
- Detailed visualization and diagnostic tools for a complete picture of the sources of interference and how to mitigate them.
- Scenario matrix for rapid, high-level visualization of problematic RFI issues.
- Signal traceback in interaction diagrams for detailed graphical information identifying the root-cause of the RFI.
- Wideband plots of received interference power with pointers identifying each contributor and its root-cause.
- Early simulation in the design of wireless devices to catch, diagnose and mitigate RFI issues.
