■ Baseband HW iIntroduction

This document specifies the baseband module for the Nokia 2600. The baseband module includes the baseband engine chipset, the UI components and the acoustical p arts for the transceiver.

Nokia 2600 is a hand-portable dualband 900/1800MHz or Low band/High ba nd phon e, featuring the DCT4 generation baseband (UEM/UPP) and RF (MJOELNER) circuitry.

■ Technical summary

The baseband module contains 2 main ASICs named the UEM and UPP. The baseband module furthermore contains a Flash IC of 32Mbit. The baseband is based on the DCT4 engine program.
