LOW-NOISE AMPLIFIER FOR CARRIER AGGREGATION AND APPARATUS INCLUDING SAME

摘要

According to an embodiment of the present disclosure, an apparatus comprises: an input terminal receiving an input signal including at least one carrier wave; a first amplifier stage connected to the input terminal, enabled in a first mode to output a first output signal by amplifying the input signal, and disabled in a second mode; and a second amplifier stage connected to the input terminal, enabled in the second mode to output second and third output signals by amplifying the input signal. Therefore, a low-noise amplifier for carrier aggregation can efficiently support variously arranged frequency channels.;COPYRIGHT KIPO 2018
