It goes without saying that filters are crucial for achieving acceptable RF/microwave system performance. For engineers who are tasked with designing filters, software tools are available to streamline the design process. This article dives into one such example by presenting a design process of a miniature hairpin resonator filter, which can be designed in a short amount of time thanks to the capabilities of current software tools.
One company that specializes in filter design software is Nuhertz Technologies. The company’s FilterSolutions software can be used to design lumped-element, distributed, active, and digital filters. In addition, FilterSolutions can be used together with various third-party electromagnetic (EM) simulators, as filter designs in FilterSolutions can be exported to third-party EM simulators for simulation and analysis.
