For planar filters, the Ansys tool offers geometries relevant to the type of filter chosen and predicts the filter response as each is selected. They are also used in RF transmitters and receivers to improve selectivity and sensitivity by removing undesired frequencies, and in ADC and DAC conversions. RF and microwave filters: widely used in electronics applications to pass or block some signal components in the RF spectrum.The tool also eliminates the need for multiple prototype stages, Carpenter said.įilter categories that can be designed and synthesized by the new tool include: The modeling and simulation tool also: automates filter design and synthesis provides virtual prototyping of filters via physics simulation and assesses yields, process tolerances and relevant effects such as electrical loss, heating, mechanical deformation and stress. The design can then be pushed to HFSS for validation. The new tool is “used it as a front-end to our electromagnetic simulation suite, the ANSYS HFSS software, in order to provide a tool able to design, synthesize, virtually test, tune and optimize filters, making them suitable for manufacturing tolerances”.Ī FilterQuick interface (below) allows also non-expert users to design and synthesize filters, with all the controls available in a single panel. “It is difficult to find RF designers who are acquainted with and have the expertise for filter design,” said Shawn Carpenter, Ansys product manager for Nuhertz FilterSolutions. An CAE-based approach can provide a tuning-free design independent of manufacturing or component tolerances. An accurate prototype design can help.įilter designs lacking accuracy often translate into a long, expensive tuning phase requiring consideration of component tolerances.
INTEGRATED CIRCUIT DESIGN SOFTWARE SOFTWARE
EM software often proves inadequate for the optimization of high-end filters. RF and microwave filters are prone to EM cross-coupling, which is often a source of inaccuracies in traditional circuit modeling approaches.
INTEGRATED CIRCUIT DESIGN SOFTWARE SIMULATOR
The tool automatically sets up filter analysis and optimization in the company’s HFSS 3D high frequency electromagnetic (EM) simulator software.įilter design is complex, especially for high-performance microwave and millimeter-wave designs. The Nuhertz FilterSolutions workflow starts by entering filter performance specifications used by the tool to synthesize both ideal and physical filter layout.
The RF filter software aids in the design, synthesis and optimization of RF, microwave and digital filters, thereby lowering development costs while boosting performance. Ansys, the simulation software specialist, has added software designed to spin up RF filters.
