1.2
The MRF24J40MA is a surface mountable module.
Module dimensions are shown in Figure 1-3. The
module Printed Circuit Board (PCB) is 0.032" thick with
castellated mounting points on the edge. Figure 1-4 is
a
MRF24J40MA.
The MRF24J40MA 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 1.2", be
kept clear of metal objects. A host PCB ground plane
around the MRF24J40MA acts as a counterpoise to the
PCB antenna. It is recommended to extend the ground
plane at least 0.4" around the module.
