Note1
：
Keep out the area below the test point in the host PCB. Place solder mask.
Note2
：
In order to maintain the module, keep about 3mm between the module and other
components in host PCB.
Note3
：
Keep out area in above figure in which is forbid to pour ground copper. Since the RF
test point in this area, avoid generating parasitic capacitance between RF test point
and ground.
