Mounting Details

The MRF89XAM8A is a surface mountable module, the

module dimensions are illustrated in Figure 1-3. The

module PCB is 0.032" thick with castellated mounting

holes on the edge. Figure 1-4 is the recommended host

PCB footprint for the MRF89XAM8A.

The MRF89XAM8A has an integrated PCB antenna.

For the best performance, follow the mounting details

as illustrated in Figure 1-5. It is recommended that the

module be mounted on the edge of the host PCB and

an area around the antenna, approximately 3.4" (8.6

cm), be kept clear of metal objects for best

performance. A host PCB ground plane around the

MRF89XAM8A acts as a counterpoise to the PCB

antenna. Extend the host PCB top copper ground plane

under and to the left and right side of the module at

least 0.4 inches (1 cm) for best antenna performance.
