RF PCB layouts are usually designed as planar structures. However, the connection of the RF PCB to the external world is usually through some 3D connectors, such as SMA launchers. The RF path contains planar and 3D components that need to be EM simulated, tuned, and optimized. Learn how to avoid guesswork in RF performance by accurately including the EM effects of 3D components in your planar RF layout design in this tutorial video.
