CST has introduced its new Filter Synthesis Tool, the Filter Designer 2D. This tool has been added to the CST Studio Suite, allowing the synthesis, electromagnetic simulation, optimization and multiphysics analysis of filters in one single environment, according to the company.
“Planar filters are widely used by engineers developing low-cost or compact printed electronics for applications such as networking, communication and signal processing. For these filters, the design process typically has two stages. The first step is selecting an appropriate filter topology from a synthesis tool or textbook and calculating the filter coefficients that match the specification. The second step is analyzing and fine-tuning the filter through simulation or prototyping to ensure that it operates correctly when installed,” the company said.
This new Filter Designer 2D has a database with a large variety of types of filters. Filters can include both lumped element and distributed element implementations. The user can simply enter specifications into the filter and the device will suggest a design type for the user. Fully parametric models of this design can then be created for either circuit simulation or full-wave 3D simulation.
“Filter Designer 2D is a major advance in our planar filter design offering. By automating the filter design process wherever possible, we want to free engineers to focus on the bigger picture,” Dr. Bernhard Wagner, managing director at CST, said.
