G30 - Module Hardware Description
December 15, 2009
The G30 consists of the following blocks:
Baseband
The baseband IC is combined with the RF transceiver and the power management unit (PMU).
This chipset provides all baseband and low power RF band functionality for GPRS/GSM, and
includes:

RF Block
The G30 RF section is designed with minimum discrete parts, making it more reliable.
The RF block consists of:
•
RF Transceiver/Receiver block in the same single chip IC as the MCU
•
2 Rx Filters
•
RF power amplifier and Front End Module in single chip IC
