Tx IQ tuning must be performed for all GSM bands. Steps 1. Start Phoenix service software. 2.

RM-70 System module Nokia Customer Care Phone description Introduction This chapter describes the baseband module including engine, power management, interfaces, audio etc. The baseband is based on BB5.0 with a RAPGSM main processor and Retu/Tahvo energy management. All blocks that require high voltage process are in Tahvo and all other in Retu. The RF part is based on the ASIC Ahne. RM-70/Nokia 7370 operates on the GSM900/1800/1900 bands.

RM-70 System module Nokia Customer Care • Ahne RF ASIC (application specific integrated circuit) • Front end module (FEM) module (Power amplifier and Antenna switch) The RF engine also includes: • Voltage controlled oscillators (VCO and VCTCXO) • SAW filters The baseband section controls the RF module through the serial bus, RFBus. This passes information about eg. frequency band and mode of operation. Ahne RF ASIC controls the mode of operation, and further sends control signals to the front end module.

RM-70 System module Nokia Customer Care Modes of operation The functional behavior can be divided into seven different states. Since the UEMEK controls the regulated power distribution of the phone, each of these states will affect the general functionality of the phone: • No supply • Backup • Power off • Reset • Power on • Deep sleep Battery and charging Battery Note: For technical data, see Battery endurance (page ). This device uses the BL-4B battery, a 700 mAh minimum Li-ion battery.

RM-70 System module Nokia Customer Care Charging This phone is charged through the smaller Nokia standard interface (2.0 mm plug). The old standard charger (3.5 mm) can be used together with the CA-44 charger adapter. Figure 52 Old (left) and new (right) charger plugs Charging is controlled by energy management, and external components are needed to protect the baseband module against EMC, reverse polarity and transient frequency deviation.

RM-70 System module Nokia Customer Care Figure 57 RAPGSM/Retu SIM interface connections SIM Logic level shifting The SIM interface can be programmed to support 3V and 1.8V SIM cards. Retu contains a SIM interface called Logic level shifting. A register in Retu selects the supply voltage when the SIM interface is powered down. SIM Power up/down The SIM power up/down sequence is generated in Retu. This means that Retu generates the reset switch (RST) signal to the SIM.
