Technological improvements in the THF-13 are the nominal battery voltage which is 3.6 V and operating voltage on logic chips , 2.8 V. The
ROMless CPU necessitates the use of an external program memory
(flash).
The transceiver consist of four modules: UIF module, rf/system module,
battery pack and mechanics.
The user interface has fully graphical LCD–display and keybord with side
volume keys.

General Information
The electrical specifications below list the bottom connector signals and
levels in the baseband. The system connector is used to connect the
transceiver to accessories. The System connector pins can also be used
to connect intelligent battery packs to the transceiver. The table gives the
idle voltage produced by the acceptable chargers at the DC connector input. The absolute maximum input voltage is 30 V due to the transient
suppressor that is protecting the charger input.

General Information
Functional Description
Circuit Description
The transceiver electronics consist of a UI module PCB and a RF/system
PCB. The UI module is connected to the system module with a connector. The System and rf submodules are interconnected with PCB wiring.
The unit can be connected to accessories with a bottom system connector, which includes charging and accessory control.
The RF block is designed for a hand portable phone operating in NMT450
systems. The purpose of the RF module is to receive and demodulate
radio frequency signal from a base station and to transmit a modulated
RF signal to a base station.

Block Diagram
The THF–13 consist of 2 pcbs, NH1 and NU1. The NH1 consist of 2 submodules, BASEBAND and RF. The BASEBAND consist of 3 functional
blocks: PWRU, CTRLU and AUDIO and RF consist of 3 ones: RX, SYNT,
TX. NU1 is the User Interface module (UIF–module).
