Fig. 5 GS2101MIx Module Dimensions (in millimeters)
Notes:
1. All Dimensions are in millimeters (mm).
2. For Boards using PCB Antenna, we recommend:
–
Have Only Air on BOTH sides of the antenna.
–
Hang Antenna over edge of the base board (best)
–
Or Cut notch in base board under antenna area
–
5mm beyond module edge on both sides is good
–
Full module width is minimum
–
No metal or FR4 encircling antenna area
–
Antenna at edge of base board, not interior of base
board
–
Nothing conductive near antenna (for example battery,
display, wire)
3. The 3 RF shield mounting holes and 2 test fixture alignment
holes (circled in red in Fig. 4, page 44) have exposed metal.
These areas must not have metal on the customer board.
4. For best RF performance, we recommend:
–
Using the power (PWR) or the GND planes from module
back to the power supply.
–
Isolating PWR/GND from high frequency or high current
components. For example, a notch in GND plane to isolate
from host µC.
