Introduction
The NHE4 is a radio transceiver unit for the GSM network. 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.
