Abstract
A system includes a printed circuit board (PCB). The PCB includes a radio frequency (RF) circuit that includes a plurality of circuit modules and signal trace lines. Each circuit module is electrically connected to at least one other circuit module by a signal trace line. The system includes a via fence comprising fence walls having at least two materials laminated using a printed wire board (PWB) process. The fence walls include a plurality of vias. The fence walls form a plurality of free-form RF isolation chambers, each chamber includes chamber walls that surround each circuit module outside of the PCB. The embodiments also include a method of manufacturing and/or isolating the system or components of the system.
