Antenna location is important; we recommend directing the antenna away from high-speed

switching signals. Furthermore, the trace from the module to the antenna should be as
short as possible and must be shielded by complete grounding.

The M14Q2SG is well shielded; the high-speed elements on a system should have shielding

reserved during the early stages of development.

3.5. Radiated sensitivity measurement

Over-the-air testing can demonstrate the TRX ability of the whole system. Keys elements that affect the
measurement are:

Module ability (refer Specification)
Antenna Gain
System noise source

The OTA performance should be performed in an OTA chamber.

3.6. GNSS external circuit design

One GNSS SAW filter, LNA, and another GNSS SAW filter need to be used between the module and
antenna.
