Abstract: Disclosed is a 5G (5th generation) or pre-5G communication system for supporting a data transmission rate higher than that of a 4G (4th generation) communication system such as long-term evolution (LTE). A transmission device comprises: a first amplification unit having a common source structure, including cross coupled capacitors, and amplifying an input signal; a second amplification unit, having a common gate structure, for amplifying a signal output from the first amplification unit; and a first removal unit which is connected to output terminals of the first amplification unit and input terminals of the second amplification unit and which removes at least one portion of second harmonics. The first removal unit can offset, with respect to a fundamental frequency, at least some of parasitic capacitance generated from the output terminals of the first amplification unit and the input terminals of the second amplification unit, and can ground a signal having a secondary harmonic frequency with respect to the secondary harmonic frequency.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). An electronic device including a first radio frequency (RF) chip and a second RF chip is provided. The electronic device includes a modem configured to transmit a first clock signal to the second RF chip, the first RF chip connected to the modem and configured to receive a second clock signal from the modem, and the second RF chip electrically connected to the first RF chip through a transmission line and configured to receive the second clock signal from the first RF chip and to measure a phase of the transmission line based on the first clock signal and the second clock signal. The first clock signal and the second clock signal have different frequencies.
