1. A radio frequency (RF) module, comprising:
- a first substrate to receive passive circuits; and
a second substrate to receive active circuits, the first and second substrates electrically coupled through pads positioned on opposing surfaces of the first and second substrate;
a printed circuit board (PCB) having pads positioned thereon, the pads being adapted to electrically couple with pads on a remaining surface of the first substrate; and
one or more via holes in the first substrate, and wherein a PCB ground is electrically coupled to the second substrate through the one or more via holes.
