Includes USB bus current.
b.
Peak consumption averaged over 100µs.
c.
Current consumption increases by 50mA with a 6dB return loss-based load-pull.
d.
GSM mode peak current increases to 2.2A (from nominal 1.6–1.7A) with 6dB return loss-based load-pull.
The host device must provide power to the AirPrime soldered-down module over pins 42 and 44
(VCC_3V6) as detailed in the following table.

Note:
The host must provide safe and continuous power to the module; the module does NOT have
protection circuits to guard against electrical overstress.
2.2.
Electrostatic Discharge (ESD)
The host device must provide adequate ESD protection on digital circuits and antenna ports as
detailed in the following table.
Note:
The level of protection required depends on the application.
