7 RF Design notes
7.1 Recommended RF layout and ground plane
Using the BMD-345 with the U.FL connector relies on an external antenna, there are no ground plane
requirements or keep-out area for the module itself. Refer to the external antenna datasheet for
antenna placement and grounding recommendations.
7.2 Mechanical enclosure
When using the BMD-345 with the U.FL connector, refer to the external antenna datasheet for
placement in or on a mechanical enclosure.
7.3 Approved external antennas
