Often 3D planar EM simulation technology is adequate for most laminate/LTCC/module applications; however there are cases were full-wave 3D EM simulations provide better accuracy. This episode discusses two such applications and the advantages of using FEM Simulator G2.

A Defective Ground Structure (DGS) is an intentionally designed defect on a ground plan, which creates additional effective inductance and capacitance.  This technique can be used to design microstrip lines with desired characteristics such as higher impedance, band rejection and slow-wave characteristics, while significantly reducing the footprint of the microstrip structure.  DGS structures are used [...]

A BGA package is very popular package style for high speed digital applications due to high density, low thermal resistance, and low inductance leads. However, a package is
the second most expensive part next to the silicon and can add 6 to 8 weeks to the cycle time. Given the very tight opportunity window for the [...]
