Abstract: In a 5th generation (5G) or pre-5G communication system for supporting a high data transfer rate, a method of measuring a power of a signal in an electronic device may include obtaining, by at least one sensor, a first voltage of the signal at a first point between a power amplifier and a transmission line, obtaining, by the at least one sensor, a second voltage of the signal at a second point between the transmission line and an antenna, and calculating a power of the signal, based on the first voltage and the second voltage. A length of the transmission line may be based on a wavelength of the signal. The method and corresponding electronic device reduce an error between power to be calculated and power consumed in practice.

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.
