CORE MODULE FOR CELLULAR COMMUNICATION COMPRISING A RF MODULE, A BASEBAND MODULE, A POWER MANAGEMENT MODULE, AND A MEMORY MODULE INTO A SINGLE PACKAGE MODULE

摘要

PURPOSE: A core module for communication is provided to enable the common platform of phone by selecting a module by model according to specifications in a cellular phone development.;CONSTITUTION: A core module(100) for cellular communication includes a RF module(110), a power management module(120), a memory module(130), and a base band module(140). A RF module comprises a RF receiver(111) and a RF transmitter(112). A RF receiver selectively selects a wireless signal received from an antenna through a synchronization means and performs the down-conversion of selected frequency. A RF transmitter performs the up-conversion of a base band signal transmitted to an antenna for transmission and amplifies electricity. A power management module supplies power necessary for a RF module and a base band module and provides a reference clock and a sleep clock. A memory module includes a memory like a SDRAM. A SFRAM comprises a SIPD(150) by storing the signal processing data of a base band module and being mounted with a base band module. A base band module performs a modem role in order to process a signal transmitted and received through a RF module and performs an interface function for the connection of various external devices.;COPYRIGHT KIPO 2013;[Reference numerals] (111) RF receiver; (112) RF transmitter; (120) Power amplification module; (130) Memory module; (140) Base band module; (AA) Duplexer
