Users can directly export lumped filters designed with discrete elements from user libraries into NI AWR or CST Studio Suite.

This is a 7-pole Elliptic example with Coilcraft 1008 Series S-parameter inductors and Murata 0603 temperature-compensating Spice model capacitors.įor simple low-order Elliptic filters, Coilcraft’s Filter Designer offers discrete-inductor-element-designs from Coilcraft libraries. Individual elements may be adjusted via a left-mouse click to individually select part families or S-parameter or Spice model files of specific parts (Fig. Interconnect parasitics may be neglected initially, while the design accuracy is achieved by selecting a parts family with traits suitable for the design environment. Nuhertz’s patent-pending process employs easy-to-use pop-up menus of part families that make the learning curve negligible, enabling new users to quickly create accurate lumped designs with discrete parts.
With the CST Studio Suite, other 3D features like the enclosure and connectors could be further added to the model.įor low-frequency designs (typically below 200 MHz), automated part selection generally involves just simply selecting the part family from a directory of S-parameter and/or Spice model libraries supplied by the manufacturers and/or created by the user. Accurate lumped-element designs at very high frequencies may be quickly realized when using FilterSolutions with the NI AWR software and Modelithics. In the case of higher frequencies (typically above 200 MHz), FilterSolutions exports directly into the NI AWR or CST Studio Suite design environments for interconnect simulations and further optimizations. FilterSolutions then completes the design process. Specifically, Nuhertz Technologies offers FilterSolutions, which applies the best-suited manufacturer or internal parts model automatically selected from a user-customizable database, such as the NI AWR software device library, Dassault Systèmes’ CST Studio Suite device library, or the Modelithics CLR Library within the NI AWR Design Environment platform.įor user-customizable libraries, users merely need to select a parts family, which may be custom built or supplied by the manufacturer(s).
Furthermore, at higher frequencies, parasitic effects become increasingly difficult to manage, and countless hours may be wasted in the hardware lab if inadequate software is used.įortunately, design tools do exist that overcome these limitations. Powerful design tools may thus be rendered effectively useless by any one of these problems.įor example, a tool that provides powerful synthesis may fall short when the output fails to be in a realizable form, or when users find the design process too cumbersome to waste time on. In an era of a myriad of design tools developed to “save” the filter designer time and effort, it’s exactly time and effort that may be lost due to learning curves, cumbersome workflows, and limitations of the design process itself.
