When an RF designer packages a carefully designed circuit into an enclosure, the circuit performance can change. An example is that the filter and oscillator frequency shift, and the amplifier begins oscillating. To predict such effects, you can include the 3D package structure with your RF circuit to perform 3DEM-circuit co-simulation and interactively optimize the circuit design to work within the enclosure. In this video, learn how to do it and nail the packaged RF circuit design in one pass.
