RELAY AND A CONTROLLING METHOD THEREOF HAVING AN ANTENNA ISOLATION MEASURING DEVICE TO INCREASE THE LIFETIME OF A HIGH OUTPUT AMPLIFYING UNIT

摘要

PURPOSE: A relay and a controlling method thereof having an antenna isolation measuring device are provided to detect a feedback signal and to measure antenna isolation degree within a relay.;CONSTITUTION: A connection unit(340) performs connection between a first duplexer(220) and a local oscillator signal receiver and between a second duplexer(270) and a signal detection unit. A controlling unit(330) is connected to the local oscillator signal receiver and signal detection unit. The controlling unit measures antenna isolation. The controlling unit controls relay gain. A remote connection unit(350) is connected through network to control the controlling unit in a remote site.;COPYRIGHT KIPO 2012
