Abstract
An electronic device including: a modem configured to process a baseband signal; an intermediate frequency (IF) transceiver configured to convert the baseband signal provided from the modem into an IF band signal; and a radio frequency (RF) transceiver configured to convert the IF band signal provided from the IF transceiver into an RF band signal, wherein the RF transceiver includes a power amplifier configured to amplify the RF band signal, and a temperature sensor unit to detect a temperature of the power amplifier, and wherein the modem includes a controller configured to control an input power inputted to the RF transceiver based on the temperature of the power amplifier detected by the temperature sensor unit.
