Abstract:
A Printed Circuit Board (PCB) and methods for manufacturing the PCB board are provided. The PCB includes a Radio Frequency (RF) signal transition at a RF signal pad. Multiple conductive layers other than a conductive signal layer of the PCB and conductive portions of the conductive signal layer not in electrical contact with a RF signal transmission trace have common ground connections forming a ground cage structure within the PCB around the RF signal pad and RF the signal transmission trace.
