It is GSM power class 4 transceiver providing 11 power levels at a maximum power of 2 W. The transceiver consists of three modules: system module, user interface module and mechanics. The plugin SIM (Subscriber Identity Module) card reader is located inside the phone. Functional Description The transceiver electronics consist of radio module (system + RF blocks) and UIF module. UIF module is connected to radio module with a connector. System blocks and RF blocks are interconnected with PCB wirings. Transceiver can be connected to accessories with a bottom system connector, which includes charging and accessory control. The system blocks provides MCU and DSP environments, logic control IC (ASIC), memories, audio processing and RF control hardware (RFI). On board power supply circuitry delivers operating voltage for both system and RF blocks. The micro controller unit, Hitachi H8/536, communicates with DSP, memories and logic control IC (ASIC/D2CA) with 8 bit data bus. RF block is designed for a handportable phone; which operates in GSM system. Purpose of the RF block is to receive and demodulate radio frequency signal from the base station and to transmit a modulated RF signal to the base station.

The GR8 module carries out all the system and RF functions of the tranceiver. System module GR8 is designed for a handportable phone, that operate in GSM system. Technical Section All functional blocks of the system module are mounted on a single multi layer printed circuit board. The chassis of the radio unit has separating walls for baseband and RF. All components of the baseband section are surface mountable. They are soldered using reflow. The connections to accessories are taken through the bottom connector of the radio unit. The connections to the User Interface module (UIF) are fed through a flex connector. There is no physical connector between the RF and baseband sections. WARNINGS The maximum battery voltage during the transmission should not exceed 8.0 V. Higher battery voltages may destroy the power amplifier. This will be quaranteed by hardware based limiting which has maximum value 7.6 ±0.3 V. External and Internal Connectors The system module has two connector, external bottom connector and internal UIF module connector. 4 Antenna connector 2 1 3 Battery connector 2 1 4 Charging connector 3 2 1 X100 16 9 30 1 X196 UIF module connector D0000323 1 8 System connector | ||
