ABSTRACT:
Methods of assembling a coupler are provided in which a first printed circuit board is provided, and a second printed circuit board is then surface mounted on the first printed circuit board. The first printed circuit board and the second printed circuit board are then electrically and mechanically connected to provide a coupler having a shielded region defined between the first printed circuit board and the second printed circuit board. The shielded region at least partly surrounds a coupler circuit disposed therein.
