Board Layout Guidelines
If you are at all familiar with RF devices, you may be concerned about
specialized board layout requirements. Fortunately, because of the care
taken by Linx in designing the modules, integrating them is very straight-
forward. Despite this ease of application, it is still necessary to maintain
respect for the RF stage and exercise appropriate care in layout and appli-
cation in order to maximize performance and ensure reliable operation. The
antenna can also be influenced by layout choices. Please review this data
guide in its entirety prior to beginning your design. By adhering to good
layout principles and observing some basic design rules, you will be on the
path to RF success.
Figure 19 shows the suggested PCB
footprint for the module. The actual
pad dimensions are shown in the
Pad Layout section of this manual.
A ground plane (as large as
possible) should be placed on a low-
er layer of your PC board opposite
the module. This ground plane can
also be critical to the performance of
your antenna, which will
be discussed later. There should
not be any ground or traces under the
GROUND PLANE
ON LOWER LAYER

module on the same layer as the module, just bare PCB.
During prototyping, the module should be soldered to a properly laid-out
circuit board. The use of prototyping or “perf” boards will result in horrible
performance and is strongly discouraged.
No conductive items should be placed within 0.15" of the module’s top or
sides.
Do not route PCB traces directly under the module. The underside of the
module has numerous signal-bearing traces and vias that could short or
couple to traces on the product’s circuit board.
The module’s ground lines should each have their own via to the ground
plane and be as short as possible.
