Webinar: Designing Densely Packed LC Filters With Ansys HFSS and Modelithics

About this Webinar

Accurately simulating the real-life performance of filters designed with surface-mount components is challenging due to component parasitics. The challenges are greater when components close to one another can introduce coupling effects that impact overall performance. Overcome these challenges by using EM simulation combined with 3D component models. Unlike equivalent-circuit models, 3D models account for the coupling effects in densely packed designs, making it possible to predict real-life performance in these scenarios accurately.

What You Will Learn

• How do 3D models differ from equivalent-circuit models?

We’ll explain how Modelithics 3D models are based on the physical characteristics of each component. These models can be used in full-wave 3D EM simulations, enabling designers to simulate the effects of parts close to one another.

• Case study #1: An LC filter with components spaced apart

We’ll show an LC filter designed in HFSS with components located relatively far from one another.  Simulating with equivalent-circuit models produces accurate results in this scenario due to the spacing between components.

• Case study #2: An LC filter with components close to one another

We’ll show an LC filter designed in HFSS with components close to one another. In this scenario, the most accurate results are achieved when utilizing 3D models.
