Abstract
A microwave or radio frequency (RF) device includes stacked printed circuit boards (PCBs) mounted on a flexible PCB having at least one ground plane and a signal terminal. Each of the stacked PCBs includes through-holes the sidewalls of which are coated with a conductive material. Microwave components are mounted on the flexible PCB within the through-holes, such that signal terminals of the components bond to signal terminals of respective through-holes. A conductive cover is mounted on the PCBs such that the cover is in electrical contact with the ground plane of the flexible PCB through the conductive material, forming shielding cavities around the components. The flexible PCB is folded such that the cover of one PCB faces the cover of the second PCB. The flexible PCB includes striplines or microstrips that carry RF or microwave signals to the signal terminals.
