Introduction
The NMM-3 System module (or Engine) consists of Baseband and RF sub-modules, a
summary of the function and operation of the Baseband sub-modules are described here.
System Module: Baseband
Main functionality of the baseband is implemented into two ASICs: TIKU and UEME.
Baseband block diagram:
UEME is the Universal Energy Management Enhanced IC for digital hand portable
phones. In addition to energy management, functionality UEME performs all the base-
band mixed–signal functions.
TIKU is the main digital baseband ASIC.
UEME is essentially the same as UEM, but with the following additions:
• An internal IHF amplifier saving the need for an external amplifier and the many
associated passives.
