Technical Documentation
Introduction
The THX–41 transceiver, together with battery packs BTH–8S and
BTH–8H, ensures all the desirable features e.g. alphanumeric display and
keypad, menu–control, shortcode memory facility with 98 locations,
retractable antenna etc. are available in a very small and light cellular
handportable.
The transceiver consists of two modules: a system module and a display
module.
System Module
The system module performs the following functions:
received audio processing
transmitted audio processing
data reception and transmission
Transceiver THX–41
channel selection
RF signal reception and detection of the modulated information
to baseband
modulation of the baseband microphone and data signal to the
selected channel and amplification of the signal to the selected
power level
The system module comprises a microprocessor, which controls the main
functions of the phone, and parts of the HW dependent user interface
(earphone, microphone, and alarm–beeper).
Display Module
The display module comprises a supertwist–LCD, a display driver and
keyboard contacts.
