Software Tools Bring a Unique Approach to Filter Design (.PDF Download)

No question, the task of designing high-frequency filters can be made much easier by taking advantage of the capabilities of today’s design software tools. Whatever the filter, whether lumped-element, distributed, cavity, or some other kind, simulation software is readily available to help do the job at hand. One such software tool is CST Studio Suite, a product of Dassault Systèmes. CST Studio Suite is a 3D electromagnetic (EM) analysis software package intended for designing, analyzing, and optimizing EM components and systems.

The CST Studio Suite contains two tools intended to facilitate the filter design process: Filter Designer 2D (FD2D) and Filter Designer 3D (FD3D). The FD2D tool, based on Nuhertz Technologies’ software, can be employed for the design of lumped-element and distributed filters and more. With FD2D, designers can synthesize filters based on a set of parameters.
