Claim 10:
11. A printed circuit board (PCB), comprising:
a PCB substrate including a first surface and a second surface opposite the first surface, wherein the PCB substrate further includes a first through-hole cavity from the first surface to the second surface, and wherein the PCB substrate further includes a second through-hole cavity from the first surface to the second surface;
a packaged radar device comprising a first signal launch and a second signal launch;
a first wave-guiding interface comprising a first set of grounded solder balls arranged around the first signal launch, wherein the first set of grounded solder balls is coupled to the packaged radar device and coupled to the first surface of the PCB substrate; and
a second wave guiding interface comprising a second set of grounded solder balls arranged around the second signal launch, wherein the second set of grounded solder balls is coupled to the packaged radar device and coupled to the second surface of the PCB substrate.
