Abstract: The disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). An operation method of a device for upconversion in a wireless communication system is provided. The method includes receiving a first local oscillator (LO) signal, generating a second LO signal, based on the first LO signal and cross-coupled latches, receiving an input signal, generating an upconverted frequency, based on the second LO signal and the input signal, generating an output signal obtained by processing a harmonic component included in the upconverted frequency, and transmitting the generated output signal.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-Generation (4G) communication system such as long-term evolution (LTE). According to various embodiments of the present disclosure, an apparatus of a transmitter in a wireless communication system may include an oscillating circuit for providing an oscillating signal, and a radio frequency (RF) circuit for converting a frequency of a transmit signal using the oscillating signal, and transmitting the transmit signal. The oscillating circuit may generate a base oscillating signal of a differential signal form, by multiplying a first signal and a second signal which constitute the different signal, generate a first signal set from the first signal and a second signal set from the second signal, and generate a signal in which at least one harmonic component adjacent to an intended frequency component is suppressed using the first signal set and the second signal set.
