摘要： According to various embodiments, an electronic device may comprise a communication processor; an intermediate frequency integrated circuit (IFIC) to convert a baseband signal received from the communication processor into an intermediate frequency (IF) signal; a radio frequency integrated circuit (RFIC) convert the received IF signal into a first radio frequency (RF) signal; an ultra-wideband (UWB) integrated circuit (IC) generating a UWB signal corresponding to a first frequency; at least one UWB antenna to transmit/receive the UWB signal corresponding to the first frequency; and at least one first switch connected between the UWB IC and the UWB antenna. The at least one first switch may be controlled so that the UWB signal corresponding to the first frequency, generated by the UWB IC, is transmitted to the RFIC in a state in which a communication operation, for a signal transmitted/received from the communication processor, by the RFIC is inactivated.
