The singlet, containing one resonator and generating a transmission zero, is the fundamental building block for modular elliptic filter design. The study introduces the nonresonating node model (NRNM) to enhance modular design of elliptic filters. Higher‑order filters are built by cascading singlets to create transmission zeros, with the NRNM guiding this modular construction, which is validated through designed and measured example filters. The NRNM enables highly modular elliptic filter design.
The singlet, which contains one resonator and generates one transmission zero, is introduced as the most basic building block for modular design of elliptic filters. Higher-order elliptic filters are designed by cascading singlets to generate the required transmission zeros. A novel model, the nonresonating node model (NRNM), which contains both resonating and nonresonating nodes is then introduced. The model allows a high level of modularity in the design of elliptic filters. Example filters are designed and measured to validate the model and the design approach.
