5.3 RF Trace Layout Design
The Tile is certified with a PCB edge SMA connectors
[
for the RF and GPS outputs, with a micro-strip trace layout (along with
copper keep-out areas) as shown in
Figure 10
. The thicknesses of the PCB layers is shown in
Figure 11
. Although the figure shows an example 4 layer PCB only the top and inner layer 1 are
strictly required.

Note 1:
The location for the module input and bypass capacitance
Note 2:
SAT_RF track has a width of 0.343mm and is designed to support a 50 Ohm
microstrip with a ground plane on layer 2. Ensure 0.635mm of clearance between the top
copper pour and the RF SMD pad. Ensure 0.381mm of clearance between the top copper pour
and the RF tack.
Note 3:
GPS_RF track has a width of 0.343mm and is designed to support a 50 Ohm microstrip
with a ground plane on layer 2. Ensure 0.635mm of clearance between the top copper pour and
the RF SMD pad. Ensure 0.381mm of clearance between the top copper pour and the RF tack.
Note 4:
Mounting hole - 1.067mm diameter
