1. An electronic device comprising:
a plurality of radio frequency integrated circuits (RFICs) configured to deliver a digital signal to be transmitted by a modem through an antenna configured to transmit and/or receive a radio frequency (RF) signal, in a form of the RF signal and to deliver the RF signal, received from the antenna, in a direction of the modem, wherein the plurality of RFICs are at least partially connected to one another;
an inter frequency integrated circuit (IFIC) connected to at least one RFIC among the plurality of RFICs and configured to receive the digital signal from the modem, to convert the digital signal to an inter frequency (IF) signal, to deliver the IF signal to the RFIC, to convert the RF signal delivered from the RFIC to the IF signal, and to deliver the IF signal to the modem; and
a plurality of compensation units respectively connected to the plurality of RFICs or respectively positioned inside of the plurality of RFICs, the compensations units comprising circuitry configured to compensate for a loss of the IF signal occurring between the IFIC and the at least one RFIC or to compensate for a loss of the IF signal occurring between the plurality of RFICs.
