RF-35 PCB Mixed-Signal Stackup: Partitioning RF and Digital Return Paths

Mixed RF-and-digital boards rarely fail because the engineer forgot a trace-width rule. They fail when the stackup, plane strategy, and return path are treated as separate documents. This article uses an RF-35 PCB example to explain how a project team can partition RF and digital functions while keeping the board manufacturable. RF-35 ceramic-filled PTFE/glass materials...
