![]() By leveraging reusable, parameterized 3D EM building blocks for cavities and resonators in the filter, the synthesis and design stages are simplified, and the design is then highly re-usable. Thus, the designer developed a complete “synthesis to implementation” process for helical, cavity-based bandpass filters, enabling, within one integrated project, the rapid exploration of new designs through changes in a small number of key global parameters. 3D electromagnetic (EM) geometry creation and simulation for cavity-based filters is generally very time intensive. Even though the devices are tuned, it can be challenging to size all the components such that the tuning elements are effective to meet desired synthesized response. Cavity-based filter performance is determined entirely by geometry.
