RH-53/54 8-System Module Nokia Customer Care Introduction This document specifies the baseband module for the RH-53/54 platform program. The baseband module includes the baseband engine chipset, the UI components and the acoustical parts for the transceiver. RH-53/54 is a hand-portable dualband GSM/GPRS 900/1800MHz fold-phone, having the DCT4 generation baseband (UEM/UPP) and RF (MJOELNER) circuitry. The RH-53 platform also supports a GSM 850/1900 US variant called RH-54.
RH-53/54 Nokia Customer Care 8-System Module The UEM supplies both the baseband module as well as the RF module with a series of voltage regulators. Both the RF and baseband modules are supplied with regulated voltages of 2.78 V and 1.8V. UEM includes 6 linear LDO (low drop-out) regulators for baseband and 7 regulators for RF. The UEM is furthermore supplying the baseband SIM interface with a programmable voltage of either 1.8 V or 3.0 V. The core of the UPP is supplied with a programmable voltage of 1.

RH-53/54 Nokia Customer Care 8-System Module Technical Specifications ■ Modes of Operation RH-53/54 baseband engine has six different ‘normal’ operating modes: • Νo supply • Power off • Αcting dead • Active • Sleep • Charging No supply In this mode the phone has no supply voltage. The phone enters this mode if the battery is disconnected, or the battery voltage drops below VMSTR- (1.8V~2.
RH-53/54 8-System Module Nokia Customer Care Acting dead This mode is just a sub mode of normal ‘Active’ mode, where everything, except for VSIM and the RF parts, is powered up. This mode is only used for when the phone is in ‘Power off’ or ‘No supply’ mode and a charger is connected. To the user, the phone acts as if it was switched off. A battery-charging alert is given and/or a battery charging indication on the display is shown, to acknowledge the user that the battery is being charged.
RH-53/54 Nokia Customer Care 8-System Module A BSI resistor inside the battery pack indicates the battery type/size. The resistor value corresponds to a specific battery capacity and technology. The battery voltage, temperature, size and current are measured by the UEM, and controlled by the charging software running in the UPP. The charging control circuitry (CHACON) inside the UEM controls the charging current delivered from the charger to the battery.

RH-53/54 Nokia Customer Care 8-System Module Baseband - RF interface The interface between the baseband and the RF can be divided into three categories: - The digital interface from the UPP to the RF ASIC (Mjoelner). The serial digital interface is used to control the operation of the different blocks in the RF ASICs. - The analogue interface between UEM and the RF. The analogue interface consists of RX and TX converter signals.

RH-53/54 Nokia Customer Care 8-System Module RF Functional Descriptions ■ RF block diagram Block diagrams of direct conversion receiver and transmitter RF section has described in the following figure. The architecture is based on Mjoelner, the RF ASIC, which contains most of the functionality of the RF Engine. The ASIC contains RX and TX functions, VCXO (crystal is placed external to the ASIC), se the block diagram.
RH-53/54 8-System Module Nokia Customer Care The VCO for the 900/1800 (RH-53) bands covers the range of 3420 to 3840 MHz, while the VCO for 850/1900 (RH-54) (and thereby the quad band) covers 3296 to 3980 MHz. PLL Synthesizer, Functional Description The frequency synthesis PLL in conjunction with the VCO and 2/4 dividers generates the LO signal for both RX and TX paths, locked to the VCXO which again is locked to the base station through the AFC.
RH-53/54 Nokia Customer Care 8-System Module AGC The AGC keeps the BB level form the receiver within a certain range in order to stay within the dynamic range for the BB, even during fading. ■ Transmitter The transmitter chain consists of two direct frequency I/Q-modulators, one for the GSM850/EGSM900 and one for GSM1800/1900, and a dual-band power amplifier. The I/Q-signals, generated in BB, are fed to the individual I/Q-modulators in the RF-ASIC.
