System Module GP3
Introduction
GP3 is the baseband/RF module of the THF±9 cellular tranceiver. The
GP3 module carries out all the system and RF functions of the tranceiver.
The system module GP3 is designed for a handportable phone, that operates in the NMT 450i system.
Technical Section
All functional blocks of the system module are mounted on a single multi layer printed circuit board. The chassis of the radio unit contains separating walls for baseband and RF. All components of the baseband are surface mountable. The connections to accessories are fed through the bottom connector of the radio unit. The connections to user interface ±module (UIF) are fed through board to board connector. There is no physical connector between RF and baseband.
External and Internal Connectors
The system module has two connector, external bottom connector and internal UIF module connector.

Baseband Module
Introduction
Baseband module controls the internal operation of the phone. It controls the user interface, i.e. LCD driver, keyboard and audio interface functions. The module performs all signalling towards the system and carries out audio±frequency signal processing. In addition, it controls the operation of the transceiver and stores tuning data for the phone.
Technical Summary
All functional blocks of the baseband are mounted on a single multi layer printed circuit board. This board contains also RF±parts. The chassis of the radio unit contains separating walls for baseband and RF. All components of the baseband are surface mountable. They are soldered using reflow. The connections to accessories are fed through the bottom connector of the radio unit. The connections to User Interface ±module (UIF) are fed through a board to board connector. There is no physical connector between RF and baseband.

Technical Specifications
Modes of Operation
The module has three operating modes: stand±by ,listening and the conversation mode.
Standby mode:
CPU`s clock is switched off, only NIPA timer is running to take care battery save timings.
If charger is connected CPU`s clock doesn`t go to standby mode.
