Tx Pulse
: The average peak current during a GSM850 transmission burst period. The transmission burst duration
for GSM850 can vary, 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.
