SCALA1 Module Integration Guide Version 1.0.1
Antenna placement in Host product
The module has a PCB trace “F” antenna with 0 dBi gain in the max. direction.
The antenna is located outside the RF shield of the module and must be kept free of conductive
parts and wires.
The PCB antenna is located under the silkscreen text “BLE ANT” on the PCB component side and is
visible on the non-component side of the module PCB
GND considerations in Host product
The module antenna uses the GND plane of the module and is not dependant of the host GND
plane construction.
RF exposure considerations of Host product
Because the radiated power (EIRP) is 0 dBm and only the integrated antenna can be used, the
host product cannot radiate dangerous amounts of RF energy that can be absorbed by the user.
The host is “mobile” and must be more than 20 cm from the users head and body at all times
Other considerations
This module may not be co-located with other transmitters or transmit simultaneously with radios
within 20 cm.
