Introduction
The NHE–3 is a radio transceiver unit for the Pan–European GSM network. It
is GSM power class 4 transceiver providing 11 power levels at a maximum
power of 2 W. GSM is originally Pan–European digital cellular network stan-
dard, but later phrased as the Global System for Mobile Communications. The
standard is defined together by all related parties in the European Telecommu-
nications Standard Institute, ETSI.

The transceiver consists of three modules: system module, user interface mod-
ule and mechanics.
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. Sys-
tem blocks and RF blocks are interconnected with PCB wirings. Transceiver
can be connected to accessories with a bottom system connector, which in-
cludes charging and accessory control.
The system blocks provides MCU and DSP environments, logic control IC
(EDSA), memories, audio processing and RF control hardware (RFI). On board
power supply circuitry delivers operating voltage for both system and RF
blocks.
The general purpose microcontroller, Hitachi H8, communicates with DSP, me-
mories and logic control IC (EDSA) with 8 bit data bus.
RF block is designed for a handportable phone; which operates in GSM sys-
tem. Purpose of the RF block is to receive and demodulate radio frequency sig-
nal from the base station and to transmit a modulated RF signal to the base
station.
