SIGNAL CONVERTING APPARATUS AND RECEIVING APPARATUS FOR SUPPORTING CONCURRENT DUAL BANDS IN WIRELESS COMMUNICATION SYSTEM

Abstract

A receiving apparatus in a wireless communication system includes: an antenna configured to receive a wireless frequency signal including a first frequency band signal and a second frequency band signal; a low noise amplifier (LNA) configured to amplify the wireless frequency signal, output the first frequency band signal as a differential phase signal, and output the second frequency band signal as a common phase signal; a differentiator configured to pass only the differential phase signal between the signals outputted from the LNA; and a combiner configured to pass only the common phase signal between the signals outputted from the LNA.
