– 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 M14Q2F 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.
