MRF89XAM9A

1.2 Mounting Details

The MRF89XAM9A is a surface mountable module.

Module dimensions are shown 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 MRF89XAM9A.

The MRF89XAM9A has an integrated PCB antenna.

For the best performance, follow the mounting details

shown 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

MRF89XAM9A acts as a counterpoise to the PCB

antenna. It is recommended to extend the ground plane

at least 0.4" (1 cm) around the module.
