Functional Description of DTX-3
Circuit Description
The DTX-3 application module connects the TME-3/TME-4 with the fixed telephone network and/or with any unmanned connection, e.g. telemetry, remote control, security systems, remote data retrieval.
The Data module baseband blocks provide the MCU, DSP, external memory interface and
digital control functions in the UPP ASIC . Power supply circuitry, charging, audio processing and RF control hardware are in the UEM ASIC.
The purpose of the RF block is to receive and demodulate the radio frequency signal from
the base station and to transmit a modulated RF signal to the base station.
