VBATT 3.3 V (*) 3.6 V 4.5 V (**) 50 mVpp for freq<200kHz
2 mVpp for freq>200kHz
VDD 3.1 V 4.5 V 100 mVpp
(*): This value has to be guaranted during the burst (with 2.0A Peak in GSM or
GPRS mode)
(**): max operating Voltage Stationnary Wave Ratio (VSWR) 2:1
When supplying the module with a battery, the total impedance
(battery+protections+PCB) should be <150 mOhms
