Abstract
An electronic device is disclosed and may comprise: an amplifier for amplifying a signal; a filter circuit for filtering the amplified signal; a coupler for delivering a feedback signal with respect to the filtered signal; an antenna for radiating the filtered signal to the outside; and a communication circuit for generating the signal, wherein communication circuit: generates a signal, using designated information; delivers the generated signal to the amplifier; acquires, from the coupler, a first feedback signal and a second feedback signal with respect to signals amplified by the amplifier; and determines whether there is an error in a signal transmitted to an external apparatus, on the basis of the designated information, magnitude information of the first feedback signal, and frequency information of the second feedback signal. In addition, various embodiments recognized through the specification are possible.
