4. Electrical Specifications
4.1. Power Supply Specification
Modem power(V_BATT) should be provided DC3.8V ± 0.1V, 1.5A. Modem power is
provided according to inner function and per block using DC regulated circuit.
It is controlled with each power depending on the mechanism to reduce power
consumption to a minimum. PA is used directly V_BATT because of a lot of power input
power source. Thus, It can be resulted in breakage of PA in excess of the rated input
power.
In addition, surge and ESD should be designed to block the influx in order to prevent
damage to the modem.
