Company Confidential RH-21 System Module Nokia Customer Care Transceiver RH-21 Introduction The RH-21 (Model 3520) transceiver is a single-band TDMA800 transceiver unit. The transceiver consists of engine module (1cb) and assembly parts. The transceiver has a full graphic display and the user interface is based on the Jack 3.2 UI with two soft keys. An internal antenna is used, there is no connection to an external antenna.

RH-21 System Module Company Confidential Nokia Customer Care Operational Modes There are several different operational modes. Modes have different states controlled by the cellular SW. Some examples are: Idle State (on ACCH), Camping (on DCCH), Scanning, Conversation, No Service Power Save (NSPS) previously OOR = Out of Range. In the power off mode, only the circuits needed for power up are supplied. In the idle mode, circuits are powered down and only the sleep clock is running.

Company Confidential Nokia Customer Care RH-21 System Module VR3 regulator supplies VCTCXO and Safari in RF. It's always enabled when UEM is active. When UEM is in sleep mode, VR3 is disabled. VR4 regulator supplies RF parts having low noise requirements. In light load situations, VR4 regulator can be set to low Iq-mode. VR5 regulator supplies lower band PA. In light load situations, VR5 regulator can be set to low Iq-mode. VR6 regulator supplies higher band PA and TX amplifier.

RH-21 System Module Company Confidential Nokia Customer Care Asic according to control messages from the UPP. The buzzer and an external vibra alert control signals are generated by the UEM with separate PWM outputs. UI Drivers There are discrete drivers for the MIDI speaker and keyboard LEDs. The drivers for vibra and display are inside UEM. AD Converters There is an 11-channel analog-to-digital converter in UEM. The AD converters are calibrated in the production line. UPP8M RH-21 uses UPP8M ASIC.

Company Confidential Nokia Customer Care RH-21 System Module User Interface Hardware LCD Introduction RH-21 uses a color GD51 96 x 65 full dot-matrix graphical display. The LCD module includes LCD glass, LCD COG-driver, spring connector, and metal frame. The LCD module is included with the lightguide assembly module. Interface SW and the control signals are from the UPP asic. The VIO and Vflash1 regulators supply the LCD with power.
PAGE 12
RH-21 System Module Company Confidential Nokia Customer Care The current for the LCD lights is limited by the resistor between the ISET pin of the LED driver and ground. For the keyboard lights, there are resistors in parallel. Vibra Introduction The vibra is located on D-cover and is connected by spring connectors on PWB. It is located in the left bottom side of the engine. Interfaces The vibra is controlled by the PWM signal VIBRA from the UEM.

Company Confidential Nokia Customer Care RH-21 System Module Battery Phone Battery Introduction The battery for the 3560/3520 is the BLC-2 (Li-Ion 1000 mAh). Interface The battery block contains BTEMP and BSI resistors for temperature measurement and battery identification. The BSI fixed resistor value indicates the chemistry and default capacity of a battery. BTEMP-resistor measures the battery temperature. Temperature and capacity information is needed for charge control.

RH-21 System Module Company Confidential Nokia Customer Care tracks have been drawn with respect to shielding by having ground plane over tracks, and ground close to the tracks at the same layer. All edges are grounded from both sides of PWB and solder mask is opened from these areas. Target is that any ESD pulse faces ground area when entering the phone; for example, between mechanics covers. All holes in PWB are grounded and plated through holes.

Company Confidential Nokia Customer Care RH-21 System Module common 2GHz UHFVCO module is used for operation on both low and highband. A frequency divider is integrated in the Safari. Two VHF synthesizers consist of: RX VHF Synthesizer includes integrated PLL and VCO and external loop filter and resonator. The output of RX-VHF PLL is used as LO signal for the second mixer in receiver. TX VHF Synthesizer includes integrated PLL and external amplifier, loop filter, and resonator.
PAGE 46
RH-21 System Module Company Confidential Nokia Customer Care After the Safari, the balanced RF-signal is single-ended in 1:1 balun and then filtered in SAW filter. The typical insertion loss is about –4.0 dB, and maximum less than –5.7 dB. This filter has a relatively high pass band ripple of about 1.0-1.5 dB, the largest insertion being at the high end of the band. The input and return losses are about –10 dB. Power amplifier is 50Ω/50Ω module.
