NORMAL CONDITION DECISION METHOD AND AN APPARATUS THEREOF FOR DECIDING THE NORMAL CONDITION OF THE FRONT-END OF AN RF(RADIO FREQUENCY) IN A PORTABLE TERMINAL

摘要

PURPOSE: A normal condition decision method and an apparatus thereof for deciding the normal condition of the front-end of an RF in a portable terminal are provided to decide the deterioration of the hardware characteristic of the portable terminal through a simple key operation.;CONSTITUTION: An RF unit(210) generates a transmission signal. An FEM(Front End Module)(220) offers the transmission signal generated from the RF unit to an antenna. The FEM outputs the transmission signal after isolation of the transmission signal supplied from an antenna. A controller(200) measures the level of the signal outputted from the FEM. The controller compares the level of the measured signal with a previously stored threshold level.;COPYRIGHT KIPO 2011
