PHYSICAL DIMENSIONS

Figure 4-1 shows the physical dimensions for RN4020

module. Figure 4-2 illustrates the recommended PCB

layout. It is recommended that when laying out the

carrier board for the RN4020 module, the areas under

the antenna, RF test point (semi-circular pad), and

shielding connections do not contain surface traces,

ground planes, or exposed vias.

Figure 4-3 specifies the recommended mounting

details. For optimal radio performance, it is recom-

mended that the antenna end of the RN4020 module

protrudes at least 31 mm beyond any metal enclosure.

Figure 4-4 shows an example of good and acceptable

positioning of the RN4020 on the host PCB.
