RM-30 7 - System Module Nokia Customer Care ■ Block diagram Figure 1:Baseband block diagram UEMEK supplies both baseband and RF with power via built in voltage regulators, which are connected to the battery. The RF parts use mainly 2.78 V and the baseband parts 1.8V I/O voltage. The UPP core is supplied with programmable core voltage of 1.0V, 1.3V or 1.5V. UEMEK includes 7 linear LDO (Low Drop-Out) regulators for baseband and 7 regulators for RF.
PAGE 12
RM-30 Nokia Customer Care 7 - System Module The UEMEK ASIC handles the analog interface between the Baseband and the RF section. UEMEK provides A/D and D/A conversion of the in-phase and quadrature receive and transmit signal paths and also A/D and D/A conversions of received and transmitted audio signals to and from the user interface. The UEMEK supplies the analog TXC and AFC signals to the RF section according to UPP signal control. There are also separate signals for PDM coded audio.

RM-30 Nokia Customer Care 7 - System Module Figure 5:Internal microphone connection Internal speaker The internal earpiece is a dynamic earpiece with an impedance of 32 ohms. The earpiece is low impedance one since the sound pressure is to be generated using current and not voltage as the supply voltage is restricted to 2.7V. The earpiece is driven directly by the UEMEK and the earpiece driver (EARP & EARN outputs) is a fully differential bridge amplifier with 6 dB gain.

RM-30 Nokia Customer Care 7 - System Module RF Module Description The RF module performs the necessary high frequency operations of the triple-band engine. Both the transmitter and receiver have been implemented by using a direct conversion architecture, which means that the modulator and demodulator operate on the channel frequency. No intermediate frequencies are used for up- or down-conversion. The core of the RF is an application-specific integrated circuit (RF ASIC), Helgo85.

RM-30 Nokia Customer Care 7 - System Module ■ Frequency concept The RF frequency plan is shown below. The VCO operates at the channel frequency multiplied by two or four depending on the frequency band of operation. This means that the modulated signals from baseband are directly converted up to the transmission frequency and the received RF signals directly down to the baseband frequency.

RM-30 Nokia Customer Care 7 - System Module The VCTCXO (Voltage Controlled Temperature Compensated Crystal Oscillator) generates the clock frequency of 26 MHz. This frequency is buffered in the RF ASIC and fed to the UPP. Additionally, it is used as the reference frequency for the RF PLL. The frequency of the VCTCXO is locked into the frequency of the base station with the help of an AFC voltage which is generated in the UEM by an 11 bit D/A converter.
PAGE 51
RM-30 7 - System Module Nokia Customer Care The SAW filters provide the wanted out-of-band blocking immunity. The SAW filters have approximately 2.5 to 3 dB insertion loss. The GSM 900 and the GSM 1800 filters are matched to the corresponding LNA inputs of the RF ASIC with a differential matching network (LC-type). For GSM 1900, an external LNA improves the noise figure of the receiver. The external LNA provides a gain of approximately 17 dB.

RM-30 Appendix 7A Nokia Customer Care MCU-SW There is no difference in the MCU-SW. The SW supports basically all bands. The definition if the phone is a 850 or a 900 MHz phone is done in production and decides if the phone is a 850 or 900 MHz phone during boot up. MCU flashing will not influence this setting in the flash and therefore will not have any influence on this. PP Flags (variant specific settings) are set in production as well (label place).

RM-30 Nokia Customer Care Appendix 7A Flash exchange When the flash is to be exchanged, the following steps need to be done: 1. Flash the phone with proper MCU-SW. For flashing with JIG: The power supply must be connected to the Prommer Box (FPS-8) For the first flashing procedure of a flash device, it is necessary to separate the capacitor on the backside of the JIG (by removing one jumper named capacitor). Please see the picture below.
