ELECTRONIC DEVICE FOR ADJUSTING RECEPTION GAIN FOR RF SIGNAL ON BASIS OF 2 TRANSMIT OPERATION, AND CONTROL METHOD THEREFOR

WIPO Patent Application WO/2023/282501

A1

According to various embodiments, an electronic device comprises: a radio frequency integrated circuit (RFIC) including a plurality of first low noise amplifiers (LNAs); at least one radio frequency front end (RFFE) operatively connected to the RFIC; and at least one communication processor operatively connected to the RFIC, wherein the at least one communication processor is configured to control the RFIC, on the basis of a first RF signal of a first uplink band of a first operating band being output through the RFIC, so as to set, as a first gain, a gain of at least one first LNA from among the plurality of first LNAs for processing a second RF signal of a first downlink band of the first operating band provided from the at least one RFFE to the RFIC, and control the RFIC, on the basis of at least the first RF signal and a third RF signal of a second uplink band of a second operating band different from the first operating band being simultaneously output through the RFIC, so as to set, as a second gain, the gain of the at least one first LNA for processing the second RF signal provided from the at least one RFFE to the RFIC, wherein the second gain may be smaller than the first gain.
