MLE-N2 OEM module pad dimensions¶

Refer to the picture above. All units in mm.

Round rectangle top and buttom edge 1.0 x 0.7 with corner radius 0.1 (red)
Round rectangle left edge 0.7 x 1.0 with corner radius 0.1 (green)
Round rectangle middle 1.0 x 1.0 with corner radius 0.1 (blue)

Layout considerations for the main board¶

For optimum performance of the MLE-N2 antenna the carrier board PCB should be designed so that following dimensions are met:

Board design example
Black Area is a carrier board clearance area. No components or traces/GND planes are allowed in this area. This area should be min 5mm wide from the board edge of MLE-N2 to the opposite board edge. Please note the orientation of the antenna and MLE-N2.
Red diagonal striped area is a keep out are "air gap" from any solid objects or carrier board PCB material.

Board design without MLE
Top layer of carrier board PCB (light green area above) should be free from non-isolated GND planes, traces or vias.
Black Area is a carrier board clearance area. No components or traces/GND planes are allowed in this area. This area should be min 5mm wide from the board edge of MLE-N2 to the opposite board edge.
Red diagonal striped area is a keep out are "air gap" from any solid objects or carrier board PCB material.

Guidelines for mounting in enclosure¶

Min 5mm to solid objects under and above MLE-N2 antenna area. Note that carrier board thickness can be included in the total distance to solid objects under the antenna. I.e. for a 1.6mm carrier board standoffs needs to be min 3.4mm
