Peak Tx Current
: The average peak current during a GSM 850 transmission burst period or HSDPA connection. The
transmission burst duration for GSM 850 can very, depending on what transmission scheme is being deployed
(GPRS Class 8, Class 10, GSM, etc.).
2
Total Inrush Charge
: The total inrush charge at power on expressed in Millicoulombs (mC).
Note:
Multi-Tech Systems, Inc. recommends that you incorporate a 10% buffer into the power source when
determining product load.
