Introduction
The PG4 System and PU4 UI module form the heart of the H700 series of
analogue AMPS/NAMPS phones.
The transceiver consists of two modules: a System and a UI module
System Module
The system module consists of the following:–39
– received audio processing
– transmitted audio processing
– data reception and transmission
– channel selection
– modulated RF signal reception and demodulation to baseband; this
signal is used by the UI module to drive the earpeice.
– modulation of the transmitter by the audio received from the micro-
phone located in the UI module.
General Information
– application of the modulated Tx signal to the selected power level
The system module contains a microprocessor, which controls the main
functions of the System and UI modules. For convienence the non–RF
sub–systems are referred to as the ’Baseband functions’, and the RF
sub–systems as the ’RF functions’.
The RF functions provide the RF interface with the cellular system and
demodulated audio signals to the analog sub–system, they also modulate
audio signals from the analog sub–system. The baseband functions cover
both analogue sub–systems (responsible for all audio processing
functions) and digital sub–systems (responsible for all digital signal
processing functions) and the micro–controller/software (responsible for
control and data processing functions).
UI Module
The UI module performs the following functions;–
Display with driving IC;
Backlighting circuits;
Earpiece driver circuit;
Buzzer driver circuit;
Keypad contacts and circuitry;
Accessory interface circuits;
Protection components on charger input.
